Workshop on Probing and Understanding Exotic Superconductors and Superfluids

Administration

Description


	This Workshop is meant to showcase several new approaches to the experimental and theoretical understanding of superconductors and superfluids, comparing solid-state and ultracold-atoms advances with the aim of a cross-fertilization between the two fields. It will feature topics that are rapidly developing, ranging from novel (time-resolved and k-resolved) optical spectroscopies to new trapping and imaging methods for ultracold gases, with the unifying contribution of different theoretical approaches, such as Dynamical Mean-Field theory, Diagrammatic and Quantum Monte Carlo methods. Special attention will be devoted to the exotic superfluid and superconducting states which arise from the interplay between pairing, correlations, disorder and reduced dimensionality.
