Dephasing enhanced transport in nonequilibrium strongly correlated quantum systems

JJ Mendoza-Arenas, T Grujic, D Jaksch… - Physical Review B …, 2013 - APS
A key insight from recent studies is that noise, such as dephasing, can improve the efficiency
of quantum transport by suppressing coherent single-particle interference effects. However …

Coexistence of diffusive and ballistic transport in a simple spin ladder

M Žnidarič - Physical Review Letters, 2013 - APS
We show that in a nonintegrable spin ladder system with the XX type of coupling along the
legs and the XXZ type along the rungs there are invariant subspaces that support ballistic …

Light-cone and diffusive propagation of correlations in a many-body dissipative system

JS Bernier, R Tan, L Bonnes, C Guo, D Poletti… - Physical Review Letters, 2018 - APS
We analyze the propagation of correlations after a sudden interaction change in a strongly
interacting quantum system in contact with an environment. In particular, we consider an …

Diffraction-unlimited position measurement of ultracold atoms in an optical lattice

Y Ashida, M Ueda - Physical review letters, 2015 - APS
We consider a method of high-fidelity, spatially resolved position measurement of ultracold
atoms in an optical lattice. We show that the atom-number distribution can be …

Single-site-resolved measurement of the current statistics in optical lattices

S Keßler, F Marquardt - Physical Review A, 2014 - APS
At present, great effort is spent on the experimental realization of gauge fields for quantum
many-body systems in optical lattices. At the same time, the single-site-resolved detection of …

Multiparticle quantum dynamics under real-time observation

Y Ashida, M Ueda - Physical Review A, 2017 - APS
Recent developments in quantum gas microscopy open up the possibility of real-time
observation of quantum many-body systems. To understand the dynamics of atoms under …

Dynamical quantum phase transitions in the one-dimensional extended Fermi–Hubbard model

JJ Mendoza-Arenas - Journal of Statistical Mechanics: Theory …, 2022 - iopscience.iop.org
We study the emergence of dynamical quantum phase transitions (DQPTs) in a half-filled
one-dimensional lattice described by the extended Fermi–Hubbard model, based on tensor …

Creation and dynamics of remote spin-entangled pairs in the expansion of strongly correlated fermions in an optical lattice

S Keßler, IP McCulloch, F Marquardt - New Journal of Physics, 2013 - iopscience.iop.org
We consider the nonequilibrium dynamics of an interacting spin-$\frac {1}{2} $ fermion gas
in a one-dimensional optical lattice after switching off the confining potential. In particular …

Dissipative quantum dynamics of fermions in optical lattices: A slave-spin approach

JS Bernier, D Poletti, C Kollath - Physical Review B, 2014 - APS
We investigate the influence of a Markovian environment on the dynamics of interacting
spinful fermionic atoms in a lattice. To explore the physical phenomena occurring at short …

[PDF][PDF] Quantum many-body dynamics of ultracold atoms in optical lattices

S Keßler - 2014 - opus4.kobv.de
Ultracold atoms can be trapped in periodic intensity patterns of light created by
counterpropagating laser beams, so-called optical lattices. In contrast to its natural …
