Gilbert Lonzarich

from Wikipedia, the free encyclopedia

Gilbert George "Gil" Lonzarich (* 1945 ) is a physicist at the University of Cambridge's Cavendish Laboratory .

Lonzarich acquired in 1967 at the University of California, Berkeley a Bachelor , 1970 at the University of Minnesota a master and 1973 at the University of British Columbia a Ph.D. in physics. Before joining the University of Cambridge in 1978, he worked as a postdoctoral fellow for the National Research Council of Canada and for the British Science and Engineering Research Council , first as an assistant, then as a lecturer, and since 1997 as a professor.

“The work of Lonzarich - his scientific discoveries, his innovations in material quality and experimental technique - has transformed our thinking about strongly correlated electron systems. Among his many profound contributions, the most important is perhaps his discovery that superconductivity occurs ubiquitously on the border of what was considered one of the harshest environments for superconductivity: magnetism. Indeed the theme of a superconducting dome induced by the suppression of density wave order is now widespread and familiar in contemporary condensed matter physics, and it is fair to say that it is the work of Lonzarich and collaborators that established this fundamental idea. The tour de force experimental program of Lonzarich simultaneously shattered experimental limitations on sample quality, signal detection sensitivity, high magnetic fields, high applied pressures, and low temperatures, and led to the discovery of unconventional superconductivity under applied pressure in a series of magnetic materials. ”

“Lonzarich's work - his scientific discoveries, his innovations in material quality and experimental technology - have revolutionized ideas about strongly correlated electron systems. He is particularly known for his discovery that superconductivity occurs more frequently than expected at the borderline to magnetism, which is normally considered to be contrary to superconductivity (note: superconductors usually displace magnetic fields from their interior). The model of a “superconducting dome”, which is caused by the suppression of the degree of order of the density waves, has found widespread use in contemporary solid-state physics . Lonzarich's experimental masterpiece lies in the simultaneous overcoming of the experimental limitations resulting from the quality of the sample material, from the measurement sensitivity, the strong magnetic fields, the high pressure and the low temperatures applied. It led to the discovery of "unconventional superconductivity" under high pressure in a number of magnetic materials. "
