Dissipative Bethe Ansatz: Exact Solutions of Quantum Many-Body Dynamics Under Loss
Berislav Buca, Cameron Booker, Marko Medenjak +1
We use the Bethe Ansatz technique to study dissipative systems experiencing loss. The method allows us to exactly calculate the Liouvillian spectrum. This opens the possibility of…
Symmetries and Conservation Laws in Quantum Trajectories: Dissipative Freezing
Carlos Sánchez Muñoz, Berislav Buca, Joseph Tindall +3
In driven-dissipative systems, the presence of a strong symmetry guarantees the existence of several steady states belonging to different symmetry sectors. Here we show that, when…
Dissipation Induced Nonstationarity in a Quantum Gas
Berislav Buca, Dieter Jaksch
Non-stationary long-time dynamics was recently observed in a driven two-component Bose-Einstein condensate coupled to an optical cavity [N. Dogra, et al. arXiv:1901.05974] and anal…
The isolated Heisenberg magnet as a quantum time crystal
Marko Medenjak, Berislav Buca, Dieter Jaksch
We demonstrate analytically and numerically that the paradigmatic model of quantum magnetism, the Heisenberg XXZ spin chain, does not relax to stationarity and hence constitutes a…
Heating-Induced Long-Range -Pairing in the Hubbard Model
Joseph Tindall, Berislav Buca, Jonathan R. Coulthard +1
We show how, upon heating the spin degrees of freedom of the Hubbard model to infinite temperature, the symmetries of the system allow the creation of steady-states with long-range…
Exact large deviation statistics and trajectory phase transition of a deterministic boundary driven cellular automaton
Berislav Buča, Juan P. Garrahan, Tomaž Prosen +1
We study the statistical properties of the long-time dynamics of the rule 54 reversible cellular automaton (CA), driven stochastically at its boundaries. This CA can be considered…
