SUMMARY:Aucun boson n’est une île. - (Louis Garbe / LPT / Seminar). - 17/12/2024\, 14H
DESCRIPTION:Séminaire LPT \nLouis Garbe (Université technique de Munich) \nSeminar LPT\, 17/12/2024\, 14H\, 3R4\, salle de conférence \nSummary\nQuantum effects in transport are often associated with spatial coherence properties\, ie\, the ability of a particle to delocalize across several lattice sites. In this talk\, I will argue that non-trivial effects can also be observed in the absence of spatial coherence\, in particular signatures of the particle statistics. When bosons (fermions) hop incoherently on a lattice\, jumps to an occupied sites are amplified (supressed)\, even when the particles do not directly interact. \nI will present a few consequences of this effect for the transport of bosons\, through a model called Asymmetric Simple Inclusion Process (ASIP). In particular\, I will show how this Bose-enhancement of jumps to occupied sites leads to a complex non-linear dynamics\, that can be connected to topics as varied as lasing theory\, Kardar-Parisi-Zhang physics\, non-hermitian hamiltonians\, and self-pulsing in excitable systems. I will also discuss how these effects may be observed in superconducting circuit architecture.
