Biography

Müller was born in Basel, Switzerland, on 20 April 1927, to Irma (née Feigenbaum) and Paul Müller. His family immediately moved to Salzburg, Austria, where his father was studying music. Alex and his mother then moved to Dornach, near Basel, to the home of his grandparents. Then they moved to Lugano, in the Italian-speaking part of Switzerland, where he learned to speak Italian fluently. His mother died when he was 11.

In the spring of 1956 Müller married Ingeborg Marie Louise Winkler. They had a son, Eric, in the summer of 1957, and a daughter, Sylvia, in 1960. [1]

Education

After his mother’s death, Müller was sent to school at the Evangelical College in Schiers, in the eastern part of Switzerland. Here he studied from 1938 to 1945, obtaining his baccalaureate (Matura).

Müller then enrolled in the Physics and Mathematics Department of the Swiss Federal Institute of Technology (ETH) in Zürich. He took courses by Wolfgang Pauli, who made a deep impression on him. After receiving his Diplom, he worked for one year, then returned to ETH for a PhD, submitting his thesis at the end of 1957.

Career

Müller joined the Battelle Memorial Institute in Geneva, soon becoming the manager of a magnetic resonance group. During this time he became a lecturer at the University of Zürich. In 1963 he accepted an offer as a research staff member at the IBM Zürich Research Laboratory in Rüschlikon, where he remained until his retirement. In parallel, he maintained his affiliation with University of Zurich where he was appointed professor in 1970. From 1972 to 1985 Müller was manager of the ZRL physics department. In 1982 he became an IBM Fellow. He received an honorary doctorate from Technical University of Munich and University of Geneva. In 1987 (before winning the Nobel Prize) he got an honorary degree (laurea honoris causa) in Physics from the University of Pavia.

Research

For his undergraduate diploma work, Müller studied under G. Busch. He worked on the Hall Effect in gray tin, a semimetal.

Between his undergraduate degree and beginning his graduate studies, he worked for one year in the Department of Industrial Research at ETH on the Eidophor large-scale display system.

At IBM his research for almost 15 years centered on SrTiO3 (strontium titanate) and related perovskite compounds. He studied their photochromic properties when doped with various transition-metal ions; their chemical binding, ferroelectric and soft-mode properties; and the critical and multicritical phenomena of their structural phase transitions. Important highlights of this research have been published in a book written together with Tom Kool from the University of Amsterdam (publisher: World Scientific).

Nobel Prize–winning work

In the early 1980s, Müller began searching for substances that would become superconductive at higher temperatures. The highest critical temperature (Tc) attainable at that time was about 23 K. In 1983 Müller recruited Georg Bednorz to IBM, to help systematically test various oxides. A few recent studies had indicated these materials might superconduct. In 1986 the two succeeded in achieving superconductivity in lanthanum barium copper oxide (LBCO) at a temperature of 35 K. Over the previous 75 years the critical temperature had risen from 11 K in 1911 to 23 K in 1973 where it had remained for 13 years. Thus 35 K was incredibly high by the prevailing standards of superconductivity research. This discovery stimulated a great deal of additional research in high-temperature superconductivity, leading to the discovery of compounds such as BSCCO (Tc = 107 K) and YBCO (T'c = 92 K).

They reported their discovery in the June 1986 issue of Zeitschrift für Physik B.[2] Before the end of the year, Shoji Tanaka at the University of Tokyo and then Paul Chu at the University of Houston had each independently confirmed their result. A couple of months later Chu achieved superconductivity at 93 K in YBCO, triggering a stampede of scientific interest exemplified by the 1987 "Woodstock of physics", at which Müller was a featured presenter.[3]

In 1987 Müller and Bednorz were jointly awarded the Nobel Prize in physics—the shortest time between the discovery and the prize award for any scientific Nobel.

EPS Europhysics Prize

The EPS Europhysics Prize is awarded (currently every 2nd year) since 1975 by the Condensed Matter Division of the European Physical Society, in recognition of recent work (completed in the 5 years preceding the attribution of the award) by one or more individuals, for scientific excellence in the area of condensed matter physics. It is one of Europe’s most prestigious prizes in the field of condensed matter physics. Several laureates of the EPS Europhysics Prize also received a Nobel Prize in Physics or Chemistry (Geim, Novoselov, Fert, Grünberg, Kroto, Smalley, Ertl, Bednorz, Müller, Binnig, Rohrer, von Klitzing, Alferov).

Georg Bednorz

Johannes Georg Bednorz (born May 16, 1950) is a German physicist who, together with K. Alex Müller, discovered high-temperature superconductivity in ceramics, for which they shared the 1987 Nobel Prize in Physics.

High-temperature superconductivity

High-temperature superconductors (abbreviated high-Tc or HTS) are materials that behave as superconductors at unusually high temperatures. The first high-Tc superconductor was discovered in 1986 by IBM researchers Georg Bednorz and K. Alex Müller, who were awarded the 1987 Nobel Prize in Physics "for their important break-through in the discovery of superconductivity in ceramic materials".Whereas "ordinary" or metallic superconductors usually have transition temperatures (temperatures below which they are superconductive) below 30 K (−243.2 °C) and must be cooled using liquid helium in order to achieve superconductivity, HTS have been observed with transition temperatures as high as 138 K (−135 °C), and can be cooled to superconductivity using liquid nitrogen. Until 2008, only certain compounds of copper and oxygen (so-called "cuprates") were known to have HTS properties, and the term high-temperature superconductor was used interchangeably with cuprate superconductor for compounds such as bismuth strontium calcium copper oxide (BSCCO) and yttrium barium copper oxide (YBCO). Several iron-based compounds (the iron pnictides) are now known to be superconducting at high temperatures.In 2015, hydrogen sulfide (H2S) under extremely high pressure (around 150 gigapascals) was found to undergo superconducting transition near 203 K (−70 °C), due the formation of H3S, a new record high temperature superconductor.For an explanation about Tc (the critical temperature for superconductivity), see Superconductivity § Superconducting phase transition and the second bullet item of BCS theory § Successes of the BCS theory.

List of Nobel laureates by university affiliation

This list of Nobel laureates by university affiliation shows comprehensively the university affiliations of individual winners of the Nobel Prize and the Nobel Memorial Prize in Economic Sciences since 1901 (as of 2018, 904 individual laureates in total). This list considers Nobel laureates as equal individuals and does not consider their various prize shares or if they received the prize more than once. It does not include Nobel-winning organizations (as of 2018, 24 such organizations) or any individuals affiliated with those organizations. In this list, universities are presented in descending order starting from those affiliated with most Nobel Prize winners.

The university affiliations in this list are all official academic affiliations such as degree programs and official academic employment, including academic positions at research organizations formally affiliated with or operated by a university. Non-academic affiliations such as advisory committee and administrative staff are generally excluded. The official academic affiliations fall into three categories: 1) Alumni (graduate & attendee), 2) Long-term academic staff, and 3) Short-term academic staff. Graduates are defined as those who hold Bachelor's, Master's, Doctorate or equivalent degrees from a university, while attendees are those who formally enrolled in degree programs at a university but did not complete the programs; thus, honorary degrees, posthumous degrees, summer attendees, exchange students and auditing students are excluded. The category of "Long-term academic staff" consists of tenure/tenure-track and equivalent academic positions, while that of "Short-term academic staff" consists of lecturers (without tenure), postdoctoral researchers, visiting professors/scholars (visitors), and equivalent academic positions. At any university, the specific academic title solely determines the type of affiliation, regardless of the actual time the position was held by a laureate.

Further explanations on "visitors" under "Short-term academic staff" are now presented. 1) All informal/personal visits are excluded from the list; 2) all employment-based visiting positions, which carry teaching/research duties, are included as affiliations in the list; 3) as for award/honor-based visiting positions, this list takes a conservative view and includes the positions as affiliations only if the laureates were required to assume employment-level duty (teaching/research) or the laureates specifically classified the visiting positions as "appointment" or similar in reliable sources such as their curriculum vitae. To be specific, some award/honor-based visiting positions such as the "Morris Loeb Short-term Lectureship" at Harvard University and Guggenheim Fellowship are awards/honors/recognition without employment-level duty; attending meetings and giving public lectures, talks or non-curricular seminars are not employment-level duties. On the other hand, positive award/honor-based examples include "Morris Loeb Long-term Lectureship" at Harvard University (teaching duty), "Visiting Miller Professorship" at UC Berkeley (research duty) and Fulbright Scholarship. Finally, summer visitors are generally excluded from the list unless summer work yielded significant end products such as research publications and components of Nobel-winning work, since summer terms are not part of formal academic years; the same rule applies to extension schools of universities.

In this list, the number following a person's name is the year he/she received the prize; in particular, a number with asterisk (*) means the person received the award while he/she was working at the institution (including emeritus staff) containing that asterisk. A name underlined implies that this person has been listed for a same institution previously (i.e., multiple affiliations). If a person had multiple positions under one category, only the position with highest rank is listed.

Different universities adopt different criteria—from generous to conservative—for claiming Nobel affiliates, which may not encompass all types of affiliations in this list. The University Counts (Univ Counts), which are published by the universities themselves, are thus shown as comparison below. Finally, this list, together with the List of Fields Medal winners by university affiliation and the List of Turing Award laureates by university affiliation, presents the university affiliation of people who have won highest honors in fundamental academic disciplines.

Abbreviation: UG (Undergraduate), Grad (Graduate), Med (Medical), Atten (Attendee), Prof (Professor), Assoc (Associate), Asst (Assistant), Adj (Adjunct), PSD (Postdoc), Lect (Lecturer), Inst (Instructor), Res (Research/Researcher), Sci (Scientist), Fel (Fellow), Sch (Scholar), Vis (Visiting/Visitor).

Middle European Cooperation in Statistical Physics

The Middle European Cooperation in Statistical Physics (MECO) is an international conference on statistical physics which takes place every year in a different country of Europe. MECO evolved in the early 1970s with the aim of bridging the gap between the communities of scientists from the Eastern and Western parts of Europe, separated as they were by the iron curtain. Since then, MECO conferences have become the yearly nomadic reference meetings for the community of scientists who are active in the field of Statistical Physics in the broader sense, including modern interdisciplinary applications to biology, Finance , information theory, and quantum computation.

Superconductivity

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials, called superconductors, when cooled below a characteristic critical temperature. It was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, in Leiden. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor during its transitions into the superconducting state. The occurrence of the Meissner effect indicates that superconductivity cannot be understood simply as the idealization of perfect conductivity in classical physics.

The electrical resistance of a metallic conductor decreases gradually as temperature is lowered. In ordinary conductors, such as copper or silver, this decrease is limited by impurities and other defects. Even near absolute zero, a real sample of a normal conductor shows some resistance. In a superconductor, the resistance drops abruptly to zero when the material is cooled below its critical temperature. An electric current through a loop of superconducting wire can persist indefinitely with no power source.In 1986, it was discovered that some cuprate-perovskite ceramic materials have a critical temperature above 90 K (−183 °C). Such a high transition temperature is theoretically impossible for a conventional superconductor, leading the materials to be termed high-temperature superconductors. The cheaply-available coolant liquid nitrogen boils at 77 K, and thus superconduction at higher temperatures than this facilitates many experiments and applications that are less practical at lower temperatures.
