报告人简介:

Professor Thierry Giamarchi is a former student of the Ecole Normale Superieure in Paris and received his Phd from Paris XI University in 1987. He has been a permanent member of the French CNRS (National Center for Scientific Research) since 1986 and spent two years as a postdoc at AT&T Bell laboratories. In 2002 he moved as a full professor to the University of Geneva, where he is now the director of the Quantum Matter Physics Department. His research work deals with the effects of interactions in low dimensional quantum systems, such as Tomonaga-Luttinger liquids, and on the effects of disorder in classical and quantum systems for which he likes to show that they lead to novel disordered phases such as the Bose glass and the Bragg glass. He received the Abragam prize from the French Academy of Sciences and since 2013 is a Fellow of the American Physical Society and a member of the French Academy of Sciences. In addition to numerous research publications he is the author of a monograph on “Quantum Physics in one Dimension”.

报告摘要:

Transport is one of the oldest and most efficient probes in condensed mater, and one of the central ones in what concerns the potential applications of materials. Measuring the charge, heat or hall transport of a system placed in between two reservoirs is a very challenging theoretical issue since this is a steady state out of equilibrium problem. Another important challenge is provided by Hall transport for systems which are put under a (synthetic) magnetic field and for which the interacting system remains essentially an open question.

Cold atomic gases have provided novel opportunities to study and understand such transport questions, in particular in low dimensional interacting structures. I will discuss in this talk several transport realizations, such as the transport between normal or superconducting fermionic reservoirs or the Hall effect in ladder systems.

I will also discuss the experimental realizations of these systems, and discuss the challenges posed by such experiments.
