Spin-1/2 fermions: crossover from weak to strong attractive interaction
K. Ziegler
The formation and dissociation of bosonic molecules in an optical lattice, formed by spin-1/2 fermionic atoms, is considered in the presence of an attractive nearest-neighbor inter…

N-component Bose-Einstein Condensate in an Optical Lattice: Destruction of the Condensate and Quasiparticle Properties
C. Moseley, K. Ziegler
We present a model of N-component hard-core bosons on a lattice. The limit N to infinity can be solved exactly. A saddle point approximation leads to a 1/N expansion and allows the…

Electron-phonon interaction in correlated electronic systems: polarons and the formation of orbital ordering
D. Schneider, K. -H. Höck, K. Ziegler
The properties of a dilute electron gas, coupled to the lattice degrees of freedom, are studied and compared with the properties of an electron gas at half-filling, where spinless…
