Quantum Correlations in Two-Fermion Systems
John Schliemann, J. Ignacio Cirac, Marek Kus +2
We characterize and classify quantum correlations in two-fermion systems having 2K single-particle states. For pure states we introduce the Slater decomposition and rank (in analog…
Atom Optics with Microfabricated Optical Elements
G. Birkl, F. B. J. Buchkremer, R. Dumke +1
We introduce a new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing. It is based on the use of microfabricated optical el…
Partial spontaneous breaking of two-dimensional supersymmetry
E. Ivanov, S. Krivonos, O. Lechtenfeld +1
We construct low-energy Goldstone superfield actions describing various patterns of the partial spontaneous breakdown of two-dimensional N=(1,1), N=(2,0) and N=(2,2) supersymmetrie…
Loading of a Bose-Einstein condensate in the boson-accumulation regime
F. Floegel, L. Santos, M. Lewenstein
We study the optical loading of a trapped Bose-Einstein condensate by spontaneous emission of atoms in excited electronic state in the Boson-Accumulation Regime. We generalize the…
Dark soliton creation in Bose-Einstein condensates
L. D. Carr, J. Brand, S. Burger +1
It is demonstrated that stable, standing dark solitons can be created in current dilute-gas Bose-Einstein condensate experiments by the proper combination of phase and density engi…
Separable approximations of density matrices of composite quantum systems
S. Karnas, M. Lewenstein
We investigate optimal separable approximations (decompositions) of states rho of bipartite quantum systems A and B of arbitrary dimensions MxN following the lines of Ref. [M. Lewe…
