Wavepacket dynamics in energy space of a chaotic trimeric Bose-Hubbard system
Moritz Hiller, Tsampikos Kottos, Theo Geisel
We study the energy redistribution of interacting bosons in a ring-shaped quantum trimer as the coupling strength between neighboring sites of the corresponding Bose-Hubbard Hamilt…
Occupation Statistics of a BEC for a Driven Landau-Zener Crossing
Katrina Smith-Mannschott, Maya Chuchem, Moritz Hiller +2
We consider an atomic Bose-Einstein condensate (BEC) loaded in a biased double-well trap with tunneling rate and inter-atomic interaction . The BEC is prepared such that all…
Controlled quantum stirring of Bose-Einstein condensates
Moritz Hiller, Tsampikos Kottos, Doron Cohen
By cyclic adiabatic change of two control parameters of an optical trap one can induce a circulating current of condensed bosons. The amount of particles that are transported per p…
Engineering fidelity echoes in Bose-Hubbard Hamiltonians
J. D. Bodyfelt, M. Hiller, T. Kottos
We analyze the fidelity decay for a system of interacting bosons described by a Bose-Hubbard Hamiltonian. We find echoes associated with "non-universal" structures that dominate th…
Complexity in parametric Bose-Hubbard Hamiltonians and structural analysis of eigenstates
Moritz Hiller, Tsampikos Kottos, T. Geisel
We consider a family of chaotic Bose-Hubbard Hamiltonians (BHH) parameterized by the coupling strength between neighboring sites. As increases the eigenstates undergo chang…
Bifurcations in Resonance Widths of an Open Bose-Hubbard Dimer
M. Hiller, T. Kottos, A. Ossipov
We investigate the structure of resonance widths of a Bose-Hubbard Dimer with intersite hopping amplitude , which is coupled to continuum at one of the sites with strength .…
