Metastable superfluidity of repulsive fermionic atoms in optical lattices
Achim Rosch, David Rasch, Benedikt Binz +1
In the fermionic Hubbard model, doubly occupied states have an exponentially large lifetime for strong repulsive interactions U. We show that this property can be used to prepare a…
Bose-Einstein condensates of atoms with arbitrary spin
P. Van Isacker, S. Heinze
We show that the ground state of a Bose-Einstein condensate of atoms with hyperfine spin f = 2 can be either spin aligned, condensed into pairs of atoms coupled to F = 0, or conden…
The Physics of Liquid Para-Hydrogen
Thomas Lindenau, Manfred L. Ristig, Klaus A. Gernoth +2
Macroscopic systems of hydrogen molecules exhibit a rich thermodynamic phase behavior. Due to the simplicity of the molecular constituents a detailed exploration of the thermal pro…
Reaction Kinetics in a Tight Spot
Ofer Biham, Joachim Krug, Azi Lipshtat +1
The standard analysis of reaction networks based on deterministic rate equations fails in confined geometries, commonly encountered in fields such as astrochemistry, thin film grow…
