Nonequilibrium boundary-driven quantum systems: Models, methods, and properties
Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Bounds in nonequilibrium quantum dynamics
We review various bounds concerning out-of-equilibrium dynamics in few-level and many-
body quantum systems. We primarily focus on closed quantum systems but will also mention …

Floquet–Magnus theory and generic transient dynamics in periodically driven many-body quantum systems
This work explores a fundamental dynamical structure for a wide range of many-body
quantum systems under periodic driving. Generically, in the thermodynamic limit, such …

Efficient learning of ground and thermal states within phases of matter
We consider two related tasks:(a) estimating a parameterisation of a given Gibbs state and
expectation values of Lipschitz observables on this state;(b) learning the expectation values …

Defining stable phases of open quantum systems
The steady states of dynamical processes can exhibit stable nontrivial phases, which can
also serve as fault-tolerant classical or quantum memories. For Markovian quantum …

Locality of temperature
This work is concerned with thermal quantum states of Hamiltonians on spin-and fermionic-
lattice systems with short-range interactions. We provide results leading to a local definition …

Relaxation times of dissipative many-body quantum systems
M Žnidarič - Physical Review E, 2015 - APS
We study relaxation times, also called mixing times, of quantum many-body systems
described by a Lindblad master equation. We in particular study the scaling of the spectral …
