Predicting spinor condensate dynamics from simple principles
M. Moreno-Cardoner, J. Mur-Petit, M. Guilleumas +3
We study the spin dynamics of quasi-one-dimensional F=1 condensates both at zero and finite temperatures for arbitrary initial spin configurations. The rich dynamical evolution exh…
Ultracold Bose Gases in 1D Disorder: From Lifshits Glass to Bose-Einstein Condensate
Pierre Lugan, David Clément, Philippe Bouyer +3
We study an ultracold Bose gas in the presence of 1D disorder for repulsive inter-atomic interactions varying from zero to the Thomas-Fermi regime. We show that for weak interactio…
Analysis of Localization Phenomena in Weakly Interacting Disordered Lattice Gases
T. Schulte, S. Drenkelforth, J. Kruse +6
Disorder plays a crucial role in many systems particularly in solid state physics. However, the disorder in a particular system can usually not be chosen or controlled. We show tha…
Quantum polarization spectroscopy of ultracold spinor gases
K. Eckert, L. Zawitkowski, A. Sanpera +2
We propose a method for the detection of ground state quantum phases of spinor gases through a series of two quantum nondemolition measurements performed by sending off-resonant, p…
Error-Resistant Distributed Quantum Computation in Trapped Ion Chain
Sibylle Braungardt, Aditi Sen De, Ujjwal Sen +1
We consider experimentally feasible chains of trapped ions with pseudo-spin 1/2, and find models that can potentially be used to implement error-resistant quantum computation. Simi…
Trapped Ion Chain as a Neural Network: Error Resistant Quantum Computation
Marisa Pons, Veronica Ahufinger, Christof Wunderlich +5
We demonstrate the possibility of realizing a neural network in a chain of trapped ions with induced long range interactions. Such models permit one to store information distribute…
