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…
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…
Coexistence of energy diffusion and local thermalization in nonequilibrium XXZ spin chains with integrability breaking
J. J. Mendoza-Arenas, S. R. Clark, D. Jaksch
In this work we analyze the simultaneous emergence of diffusive energy transport and local thermalization in a nonequilibrium one-dimensional quantum system, as a result of integra…
Capturing exponential variance using polynomial resources: applying tensor networks to non-equilibrium stochastic processes
T. H. Johnson, T. J. Elliott, S. R. Clark +1
Estimating the expected value of an observable appearing in a non-equilibrium stochastic process usually involves sampling. If the observable's variance is high, many samples are r…
Dynamical simulations of classical stochastic systems using matrix product states
T. H. Johnson, S. R. Clark, D. Jaksch
We adapt the time-evolving block decimation (TEBD) algorithm, originally devised to simulate the dynamics of 1D quantum systems, to simulate the time-evolution of non-equilibrium s…
Cold bosonic atoms in optical lattices
D. Jaksch, C. Bruder, J. I. Cirac +2
The dynamics of an ultracold dilute gas of bosonic atoms in an optical lattice can be described by a Bose-Hubbard model where the system parameters are controlled by laser light. W…
