Computing Quantum Mean Values in the Deep Chaotic Regime
Gabriel M. Lando, Olivier Giraud, Denis Ullmo
We study the time evolution of mean values of quantum operators in a regime plagued by two difficulties: The smallness of and the presence of strong and ubiquitous classica…
Discounted Mean-Field Game model of a dense static crowd with variable information crossed by an intruder
Matteo Butano, Cécile Appert-Rolland, Denis Ullmo
It was demonstrated in [Bonnemain et al., Phys. Rev. E 107, 024612 (2023)] that the anticipation pattern displayed by a dense crowd crossed by an intruder can be successfully descr…
A social structure description of epidemics propagation with the mean field game paradigm
Louis Bremaud, Denis Ullmo
We consider the spread of infectious diseases through a Mean Field Game version of a SIR compartmental model with social structure, in which individuals are grouped by their age cl…
Resurgent revivals in bosonic quantum gases: a striking signature of many-body quantum interferences
Peter Schlagheck, Denis Ullmo, Gabriel M. Lando +1
Matter wave revivals depend on a delicate interplay of constructive many-body quantum interferences in the developing dynamics of an ultracold bosonic system in an optical lattice.…
Pedestrians in static crowds are not grains, but game players
Thibault Bonnemain, Matteo Butano, Théophile Bonnet +5
The local navigation of pedestrians amid a crowd is generally believed to involve no anticipation beyond (at best) the avoidance of the most imminent collisions. We show that curre…
Chaos-Assisted Long-Range Tunneling for Quantum Simulation
Maxime Martinez, Olivier Giraud, Denis Ullmo +4
We present an extension of the chaos-assisted tunneling mechanism to spatially periodic lattice systems. We demonstrate that driving such lattice systems in an intermediate regime…
