The Raman dressed spin-1 spin-orbit coupled quantum gas
Zhihao Lan, Patrik Ohberg
The recently realized spin-orbit coupled quantum gases (Y.-J Lin {\it et al}., Nature 471, 83-86 (2011); P. Wang {\it et al}., PRL 109, 095301 (2012); L. W. Cheuk {\it et al}., PRL…
Markovian evolution of strongly coupled harmonic oscillators
Chaitanya Joshi, Patrik Ohberg, James D. Cresser +1
We investigate how to model Markovian evolution of coupled harmonic oscillators, each of them interacting with a local environment. When the coupling between the oscillators is wea…
Light-induced gauge fields for ultracold atoms
N. Goldman, G. Juzeliunas, P. Ohberg +1
Gauge fields are central in our modern understanding of physics at all scales. At the highest energy scales known, the microscopic universe is governed by particles interacting wit…
Non-Galilean response of Rashba coupled Fermi gases
Daniel Maldonado-Mundo, Lianyi He, Patrik Ohberg +1
We consider the effect of a momentum kick on the ground state of a non-interacting two-dimensional Fermi gas subject to Rashba spin-orbit coupling. Although the total momentum is a…
On the Josephson effect in a Bose-Einstein condensate subject to a density dependent gauge potential
Matthew Edmonds, Manuel Valiente, Patrik Ohberg
We investigate the coherent dynamics of a Bose-Einstein condensate in a double well, subject to a density dependent gauge potential. Further, we derive the nonlinear Josephson equa…
