-symmetry phase transition in a Bose-Hubbard model with localized gain and loss
Cătălin Paşcu Moca, Doru Sticlet, Balázs Dóra +1
We study the dissipative dynamics of a one-dimensional bosonic system described in terms of the bipartite Bose-Hubbard model with alternating gain and loss. This model exhibits the…
Multiparticle quantum walk: a dynamical probe of topological many-body excitations
Bogdan Ostahie, Doru Sticlet, Cătălin Paşcu Moca +4
Recent experiments demonstrated that single-particle quantum walks can reveal the topological properties of single-particle states. Here, we generalize this picture to the many-bod…
Finite temperature dynamics in gapped 1D models in the sine-Gordon family
Márton Kormos, Dániel Vörös, Gergely Zaránd
The sine-Gordon model appears as the low-energy effective field theory of various one-dimensional gapped quantum systems. Here we investigate the dynamics of generic, non-integrabl…
