Dynamically Generated Double Occupancy as a Probe of Cold Atom Systems
S. D. Huber, A. Rüegg
The experimental investigation of quantum phases in optical lattice systems provides major challenges. Recently, dynamical generation of double occupancy via modulation of the hopp…
Mesoscopic Aspects of Strongly Interacting Cold Atoms
Sebastian D. Huber, Gianni Blatter
Harmonically trapped lattice bosons with strong repulsive interactions exhibit a superfluid-Mott-insulator heterostructure in the form of a "wedding cake". We discuss the mesoscopi…
The Amplitude Mode in the Quantum Phase Model
S. D. Huber, B. Theiler, E. Altman +1
We derive the collective low energy excitations of the quantum phase model of interacting lattice bosons within the superfluid state using a dynamical variational approach. We reco…
Dynamical properties of ultracold bosons in an optical lattice
S. D. Huber, E. Altman, H. P. Büchler +1
We study the excitation spectrum of strongly correlated lattice bosons for the Mott-insulating phase and for the superfluid phase close to localization. Within a Schwinger-boson me…
