-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…
Non-hermitian off-diagonal magnetic response of Dirac fermions
Roberta Zsófia Kiss, Doru Sticlet, Catalin Pascu Moca +1
We perform a comparative study for the magnetization dynamics within linear response theory of one and two dimensional massive Dirac electrons, after switching on either a real (he…
