Ferroelectric quantum criticality and enhanced superconductivity in plastically deformed strontium titanate
S. Hameed, D. Pelc, Z. W. Anderson +13
The properties of quantum materials are commonly tuned using experimental variables such as pressure, magnetic field and doping. Here we explore a different approach: irreversible,…
Simulating and detecting artificial magnetic fields in trapped atoms
Matthias Rosenkranz, Alexander Klein, Dieter Jaksch
A Bose-Einstein condensate exhibiting a nontrivial phase induces an artificial magnetic field in immersed impurity atoms trapped in a stationary, ring-shaped optical lattice. We pr…
Phonon-induced artificial magnetic fields
Alexander Klein, Dieter Jaksch
We investigate the effect of a rotating Bose-Einstein condensate on a system of immersed impurity atoms trapped by an optical lattice. We analytically show that for a one-dimension…
Optical lattice quantum Hall effect
Rebecca N. Palmer, Alexander Klein, Dieter Jaksch
We explore the behavior of interacting bosonic atoms in an optical lattice subject to a large artificial magnetic field. We extend earlier investigations of this system where the n…
Dynamics, dephasing and clustering of impurity atoms in Bose-Einstein condensates
Alexander Klein, Martin Bruderer, Stephen R. Clark +1
We investigate the influence of a Bose-Einstein condensate (BEC) on the properties of immersed impurity atoms, which are trapped in an optical lattice. Assuming a weak coupling of…
A quantum repeater based on decoherence free subspaces
Uwe Dorner, Alexander Klein, Dieter Jaksch
We study a quantum repeater which is based on decoherence free quantum gates recently proposed by Klein et al. [Phys. Rev. A 73, 012332 (2006)]. A number of operations on the decoh…
