Mobile Impurity in a Two-Leg Bosonic Ladder
Naushad Ahmad Kamar, Adrian Kantian, Thierry Giamarchi
We study the dynamics of a mobile impurity in a two-leg bosonic ladder. The impurity moves both along and across the legs and interacts with a bath of interacting bosonic particles…
Dynamics of a Mobile Impurity in a Two Leg Bosonic Ladder
Naushad Ahmad Kamar, Adrian Kantian, Thierry Giamarchi
We have analyzed the behavior of a mobile quantum impurity in a bath formed by a two-leg bosonic ladder by a combination of field theory (Tomonaga-Luttinger liquid) and numerical (…
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…
Lattice assisted spectroscopy: a generalized scanning tunnelling microscope for ultra-cold atoms
Adrian Kantian, Ulrich Schollwöck, Thierry Giamarchi
We show that the possibility to address and image single sites of an optical lattice, now an experimental reality, allows to measure the frequency-resolved local particle and hole…
Minimizing nonadiabaticities in optical-lattice loading
Michele Dolfi, Adrian Kantian, Bela Bauer +1
In the quest to reach lower temperatures of ultra-cold gases in optical lattice experiments, non-adiabaticites during lattice loading are one of the limiting factors that prevent t…
Competing regimes of motion in 1D mobile impurities
Adrian Kantian, Ulrich Schollwöck, Thierry Giamarchi
We show that a distinguishable mobile impurity inside a one-dimensional many-body state at zero temperature generally does not behave like a quasiparticle (QP). Instead, both the i…
