Dynamical disentangling and cooling of atoms in bilayer optical lattices
A. Kantian, S. Langer, A. J. Daley
We show how experimentally available bilayer lattice systems can be used to prepare quantum many-body states with exceptionally low entropy in one layer, by dynamically disentangli…
Dynamical Quasicondensation of Hard-Core Bosons at Finite Momenta
L. Vidmar, J. P. Ronzheimer, M. Schreiber +6
Long-range order in quantum many-body systems is usually associated with equilibrium situations. Here, we experimentally investigate the quasicondensation of strongly-interacting b…
Light scattering and dissipative dynamics of many fermionic atoms in an optical lattice
Saubhik Sarkar, Stephan Langer, Johannes Schachenmayer +1
We investigate the many-body dissipative dynamics of fermionic atoms in an optical lattice in the presence of incoherent light scattering. Deriving and solving a master equation to…
Sudden expansion of Mott insulators in one dimension
L. Vidmar, S. Langer, I. P. McCulloch +3
We investigate the expansion of bosons and fermions in a homogeneous lattice after a sudden removal of the trapping potential using exact numerical methods. As a main result, we sh…
The Drude weight of the spin-1/2 XXZ chain: density matrix renormalization group versus exact diagonalization
C. Karrasch, J. Hauschild, S. Langer +1
We revisit the problem of the spin Drude weight D of the integrable spin-1/2 XXZ chain using two complementrary approaches, exact diagonalization (ED) and the time-dependent densit…
Expansion dynamics of interacting bosons in homogeneous lattices in one and two dimensions
Jens Philipp Ronzheimer, Michael Schreiber, Simon Braun +6
We experimentally and numerically investigate the expansion of initially localized ultracold bosons in homogeneous one- and two-dimensional optical lattices. We find that both dime…
