The separability versus entanglement problem
Aditi Sen De, Ujjwal Sen, Maciej Lewenstein +1
We review the problem of discriminating entangled states from separable states for bipartite systems. We formally define what entangled states are, present some important criteria…
Dynamics of F=1 87Rb condensates at finite temperatures
Jordi Mur-Petit, Montserrat Guilleumas, Artur Polls +4
We investigate the dynamics of a F=1 spinor Bose-Einstein condensate of 87Rb atoms confined in a quasi-one-dimensional trap both at zero and at finite temperature. At zero temperat…
Laser cooling all the way down to Fermi superfluid
Jacek Dziarmaga, Maciej Lewenstein
Numerical simulations for realistic experimental parameters demonstrate that laser cooling on the attractive side of the Feshbach resonance can drive fermions much below the superf…
Simplifying Schmidt number witnesses via higher-dimensional embeddings
Florian Hulpke, Dagmar Bruss, Maciej Lewenstein +1
We apply the generalised concept of witness operators to arbitrary convex sets, and review the criteria for the optimisation of these general witnesses. We then define an embedding…
Finite size effects in entangled rings of qubits
T. Meyer, U. V. Poulsen, K. Eckert +2
We study translationally invariant rings of qubits with a finite number of sites N, and find the maximal nearest-neighbor entanglement for a fixed z component of the total spin. Fo…
Atom optics with rotating Bose-Einstein condensates
I. Josopait, L. Dobrek, L. Santos +2
The atom optics of Bose-Einstein condensates containing a vortex of circulation one is discussed. We first analyze in detail the reflection of such a condensate falling on an atomi…
