MPA Fisher, V Khemani, A Nahum… - Annual Review of …, 2023‏ - annualreviews.org
Quantum circuits—built from local unitary gates and local measurements—are a new
playground for quantum many-body physics and a tractable setting to explore universal …

Nonequilibrium boundary-driven quantum systems: Models, methods, and properties

GT Landi, D Poletti, G Schaller - Reviews of Modern Physics, 2022‏ - APS
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 …

Measurement-induced phase transitions in the dynamics of entanglement

B Skinner, J Ruhman, A Nahum - Physical Review X, 2019‏ - APS
We define dynamical universality classes for many-body systems whose unitary evolution is
punctuated by projective measurements. In cases where such measurements occur …

Dynamical quantum phase transitions: a review

M Heyl - Reports on Progress in Physics, 2018‏ - iopscience.iop.org
Quantum theory provides an extensive framework for the description of the equilibrium
properties of quantum matter. Yet experiments in quantum simulators have now opened up …

Irreversibility and biased ensembles in active matter: Insights from stochastic thermodynamics

É Fodor, RL Jack, ME Cates - Annual Review of Condensed …, 2022‏ - annualreviews.org
Active systems evade the rules of equilibrium thermodynamics by constantly dissipating
energy at the level of their microscopic components. This energy flux stems from the …

Dynamical quantum phase transitions in the transverse-field Ising model

M Heyl, A Polkovnikov, S Kehrein - Physical review letters, 2013‏ - APS
A phase transition indicates a sudden change in the properties of a large system. For
temperature-driven phase transitions this is related to nonanalytic behavior of the free …

Entanglement and purification transitions in non-Hermitian quantum mechanics

S Gopalakrishnan, MJ Gullans - Physical review letters, 2021‏ - APS
A quantum system subject to continuous measurement and postselection evolves according
to a non-Hermitian Hamiltonian. We show that, as one increases the strength of …

Dynamical quantum phase transitions in spin chains with long-range interactions: Merging different concepts of nonequilibrium criticality

B Žunkovič, M Heyl, M Knap, A Silva - Physical review letters, 2018‏ - APS
We theoretically study the dynamics of a transverse-field Ising chain with power-law
decaying interactions characterized by an exponent α, which can be experimentally realized …

Nonequilibrium Markov processes conditioned on large deviations

R Chetrite, H Touchette - Annales Henri Poincaré, 2015‏ - Springer
We consider the problem of conditioning a Markov process on a rare event and of
representing this conditioned process by a conditioning-free process, called the effective or …

Unraveling the large deviation statistics of Markovian open quantum systems

F Carollo, RL Jack, JP Garrahan - Physical review letters, 2019‏ - APS
We analyze dynamical large deviations of quantum trajectories in Markovian open quantum
systems in their full generality. We derive a quantum level-2.5 large deviation principle for …
