Ultrafast dynamics of strongly correlated fermions—nonequilibrium Green functions and selfenergy approximations

N Schlünzen, S Hermanns, M Scharnke… - Journal of Physics …, 2019 - iopscience.iop.org
This article presents an overview on recent progress in the theory of nonequilibrium Green
functions (NEGF). We discuss applications of NEGF simulations to describe the femtosecond …

Solvable hydrodynamics of quantum integrable systems

VB Bulchandani, R Vasseur, C Karrasch, JE Moore - Physical review letters, 2017 - APS
The conventional theory of hydrodynamics describes the evolution in time of chaotic many-
particle systems from local to global equilibrium. In a quantum integrable system, local …

Expansion dynamics of interacting bosons in homogeneous lattices in one and two dimensions

JP Ronzheimer, M Schreiber, S Braun, SS Hodgman… - Physical review …, 2013 - APS
We experimentally and numerically investigate the expansion of initially localized ultracold
bosons in homogeneous one-and two-dimensional optical lattices. We find that both …

Local shear transformations in deformed and quiescent hard-sphere colloidal glasses

KE Jensen, DA Weitz, F Spaepen - Physical Review E, 2014 - APS
We perform a series of deformation experiments on a monodisperse, hard-sphere colloidal
glass while simultaneously following the three-dimensional trajectories of roughly 50 000 …

Entanglement spreading after a geometric quench in quantum spin chains

V Alba, F Heidrich-Meisner - Physical Review B, 2014 - APS
We investigate the entanglement spreading in the anisotropic spin-1/2 Heisenberg (XXZ)
chain after a geometric quench. This corresponds to a sudden change of the geometry of the …

Dynamics of strongly correlated fermions: Ab initio results for two and three dimensions

N Schlünzen, S Hermanns, M Bonitz, C Verdozzi - Physical Review B, 2016 - APS
Quantum transport of strongly correlated fermions is of central interest in condensed matter
physics. While the stationary expansion dynamics have recently been measured with cold …

Emergent eigenstate solution to quantum dynamics far from equilibrium

L Vidmar, D Iyer, M Rigol - Physical Review X, 2017 - APS
The quantum dynamics of interacting many-body systems has become a unique venue for
the realization of novel states of matter. Here, we unveil a new class of nonequilibrium states …

Sudden expansion of Mott insulators in one dimension

L Vidmar, S Langer, IP McCulloch, U Schneider… - Physical Review B …, 2013 - APS
We investigate the expansion of bosons and fermions in a homogeneous lattice after a
sudden removal of the trap** potential using exact numerical methods. As a main result …

Expansion of one-dimensional lattice hard-core bosons at finite temperature

W Xu, M Rigol - Physical Review A, 2017 - APS
We develop an exact approach to study the quench dynamics of hard-core bosons initially in
thermal equilibrium in one-dimensional lattices. This approach is used to study the sudden …
