Resonant false vacuum decay in two dimensions on a 4000-qubit quantum annealer
Gregor Humar, Jean-Yves Desaules, Luka PaveÅ¡iÄ +4
From cosmology to quantum matter, metastable states often decay through the nucleation and growth of competing domains, with false vacuum decay providing the paradigmatic example o…
Finite-temperature crossover from coherent magnons to energy superdiffusion in the PXP model
Shengtao Jiang, Jean-Yves Desaules, Marko Ljubotina +1
The PXP chain was recently shown to exhibit superdiffusive energy transport with Kardar-Parisi-Zhang-like scaling, , joining a growing number of spin chains with this…
Coherent dynamics in chaotic spin chains via interference-protected subspaces
Aron Kerschbaumer, Jean-Yves Desaules, Maksym Serbyn
Generic quantum many-body systems are expected to thermalize, scrambling initial coherence while local observables relax to equilibrium values. Weak ergodicity breaking, often asso…
Systematic construction of quantum many-body scars in frustrated Rydberg arrays
Jean-Yves Desaules, Aron Kerschbaumer, Marko Ljubotina +1
Quantum many-body scars in Rydberg atom arrays have thus far only been observed on bipartite lattices, leaving open the question of whether and how they survive frustration, and wh…
Anomalously fast transport in non-integrable lattice gauge theories
Devendra Singh Bhakuni, Roberto Verdel, Jean-Yves Desaules +3
Kinetic constraints are generally expected to slow down dynamics in many-body systems, obstructing or even completely suppressing transport of conserved charges. Here, we show how…
Discrete solitons in Rydberg atom chains
Aron Kerschbaumer, Jean-Yves Desaules, Marko Ljubotina +1
Solitons - localized wave packets that travel without spreading - play a central role in understanding transport and properties of nonlinear systems, from optical fibers to fluid d…
