Thermoelectricity in a junction between interacting cold atomic Fermi gases
Tibor Sekera, Christoph Bruder, Wolfgang Belzig
A gas of interacting ultracold fermions can be tuned into a strongly interacting regime using a Feshbach resonance. Here we theoretically study quasiparticle transport in a system…
Optomechanical Self-Oscillations in an Anharmonic Potential: Engineering a Nonclassical Steady State
Manuel Grimm, Christoph Bruder, Niels Lörch
We study self-oscillations of an optomechanical system, where coherent mechanical oscillations are induced by a driven optical or microwave cavity, for the case of an anharmonic me…
Fragmented Superradiance of a Bose-Einstein Condensate in an Optical Cavity
Axel U. J. Lode, Christoph Bruder
The Dicke model and the superradiance of two-level systems in a radiation field have many applications. Recently, a Dicke quantum phase transition has been realized with a Bose-Ein…
Dynamics of Hubbard Hamiltonians with the multiconfigurational time-dependent Hartree method for indistinguishable particles
Axel U. J. Lode, Christoph Bruder
We apply the multiconfigurational time-dependent Hartree method for indistinguishable particles (MCTDH-X) to systems of bosons or fermions in lattices described by Hubbard type Ham…
Genuine quantum signatures in synchronization of anharmonic self-oscillators
Niels Lörch, Ehud Amitai, Andreas Nunnenkamp +1
We study the synchronization of a van der Pol self-oscillator with Kerr anharmonicity to an external drive. We demonstrate that the anharmonic, discrete energy spectrum of the quan…
