# Many-Particle Dephasing after a Quench.

@article{Kiendl2016ManyParticleDA, title={Many-Particle Dephasing after a Quench.}, author={Thomas Kiendl and Florian Marquardt}, journal={Physical review letters}, year={2016}, volume={118 13}, pages={ 130601 } }

After a quench in a quantum many-body system, expectation values tend to relax towards long-time averages. However, temporal fluctuations remain in the long-time limit, and it is crucial to study the suppression of these fluctuations with increasing system size. The particularly important case of nonintegrable models has been addressed so far only by numerics and conjectures based on analytical bounds. In this work, we are able to derive analytical predictions for the temporal fluctuations in a…

### Many-Body Dephasing in a Trapped-Ion Quantum Simulator.

- PhysicsPhysical review letters
- 2020

This Letter analyzes and observes the persistent temporal fluctuations after a quantum quench of a tunable long-range interacting transverse-field Ising Hamiltonian realized with a trapped-ion quantum simulator, and measures the temporal fluctuations in the average magnetization of a finite-size system of spin-1/2 particles.

### Detailed Balance of Thermalization Dynamics in Rydberg-Atom Quantum Simulators.

- PhysicsPhysical review letters
- 2018

This work finds that thermalization of an isolated many-body quantum state can be described by a master equation and demonstrates the detailed balance in a thermalization dynamics that does not require coupling to baths or postulated randomness.

### Relaxation, chaos, and thermalization in a three-mode model of a Bose–Einstein condensate

- PhysicsNew Journal of Physics

This review highlights recent work using trapped ions to explore a variety of non-ergodic phenomena in long-range interacting spin models, effects that are heralded by the memory of out-of-equilibrium initial conditions.

### Dynamics and level statistics of interacting fermions in the lowest Landau level

- PhysicsNew Journal of Physics

We consider the unitary dynamics of interacting fermions in the lowest Landau level, on spherical and toroidal geometries. The dynamics are driven by the interaction Hamiltonian which, viewed in the…

### Scale invariant distribution functions in quantum systems with few degrees of freedom

Scale invariance usually occurs in extended systems where correlation functions decay algebraically in space and/or time. Here we introduce a new type of scale invariance, occurring in the…

### Dynamical manifestations of quantum chaos: correlation hole and bulge

- PhysicsPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2017

It is discussed how the presence of level repulsion in lattice many-body quantum systems can be detected from the analysis of their time evolution instead of their energy spectra, advantageous to experiments that deal with dynamics, but have limited or no direct access to spectroscopy.

### Realistic Many-Body Quantum Systems vs. Full Random Matrices: Static and Dynamical Properties

The von Neumann entanglement entropy with the Shannon information entropy is related and their relevance for the analysis of the degree of complexity of the eigenstates, the behavior of the system at different time scales and the conditions for thermalization is discussed.
