The question of thermalisation in closed quantum many-body systems has received a lot of attention in the past few years. An intimately related question is whether a closed quantum system shows irreversible dynamics. However, irreversibility and what we actually mean by this in a quantum many-body system with unitary dynamics has been explored very little. In this work we investigate the dynamics of the Ising model in a transverse magnetic field involving an imperfect effective time reversal…

Predicting Imperfect Echo Dynamics in Many-Body Quantum Systems
Abstract Echo protocols provide a means to investigate the arrow of time in macroscopic processes. Starting from a nonequilibrium state, the many-body quantum system under study is evolved for a
Irreversible dynamics in quantum many-body systems
Irreversibility, despite being a necessary condition for thermalization, still lacks a sound understanding in the context of quantum many-body systems. In this work we approach this question by
Semiclassical echo dynamics in the Sachdev-Ye-Kitaev model
The existence of a quantum butterfly effect in the form of exponential sensitivity to small perturbations has been under debate for a long time. Lately, this question has gained increased interest
Tripartite information, scrambling, and the role of Hilbert space partitioning in quantum lattice models
For the characterization of the dynamics in quantum many-body systems the question how information spreads and becomes distributed over the constituent degrees of freedom is of fundamental interest.
Peculiarities of Rabi oscillations and free induction decay in two-component nuclear spin systems with Ising nuclei interactions
Nuclear spin systems in manganites, having separation of ferromagnetic and antiferromagnetic phases, which are manifested as two lines in the NMR spectrum, are studied. Taking into account the Ising
Time‐reversal invariance of quantum kinetic equations II: Density operator formalism
Time‐reversal symmetry is a fundamental property of many quantum mechanical systems. The relation between statistical physics and time reversal is subtle, and not all statistical theories conserve
Persistent many-body quantum echoes
We consider quantum many-body systems evolving under a time-independent Hamiltonian $H$ from a nonequilibrium initial state at time $t=0$ towards a close-to-equilibrium state at time $t=\tau$.
Quantum echo dynamics in the Sherrington-Kirkpatrick model
Understanding the footprints of chaos in quantum-many-body systems has been under debate for a long time. In this work, we study the echo dynamics of the Sherrington-Kirkpatrick (SK) model with

Observing the nonequilibrium dynamics of the quantum transverse-field Ising chain in circuit QED.
TLDR
It is demonstrated that quench dynamics and the propagation of localized excitations can be observed with the proposed setup and further possible applications and modifications of this circuit QED quantum simulator are discussed.
Pushing the limits of the eigenstate thermalization hypothesis towards mesoscopic quantum systems.
TLDR
This Letter presents an approach that pushes this limit up to system sizes of roughly 35 spins, thereby going significantly beyond what is possible with exact diagonalization.
Strongly correlated fermions after a quantum quench.
TLDR
This work studies the time evolution of strongly correlated spinless fermions on a one-dimensional lattice after a sudden change of the interaction strength and finds that the resulting quasistationary state is nonthermal.
Interferometric probes of many-body localization.
TLDR
It is found that for a properly chosen pulse sequence the MBL phase exhibits a characteristic power-law decay reflecting its slow growth of entanglement, and is robust with respect to thermal and disorder averaging.
Entanglement in quantum critical phenomena.
TLDR
The results establish a precise connection between concepts of quantum information, condensed matter physics, and quantum field theory, by showing that the behavior of critical entanglement in spin systems is analogous to that of entropy in conformal field theories.
Hamiltonian learning and certification using quantum resources.
TLDR
An algorithm is provided that can be used to efficiently infer the Hamiltonian of a large but untrusted quantum simulator using a trusted quantum simulator, demonstrating that quantum resources can make certifying analog quantum simulators tractable.
