Strong coupling theory for the Jaynes-Cummings-Hubbard model
S. Schmidt, G. Blatter
We present an analytic strong-coupling approach to the phase diagram and elementary excitations of the Jaynes-Cummings-Hubbard model describing a superfluid-insulator transition of…
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…
Engineering exotic phases for topologically-protected quantum computation by emulating quantum dimer models
A. Fabricio Albuquerque, Helmut G. Katzgraber, Matthias Troyer +1
We use a nonperturbative extended contractor renormalization (ENCORE) method for engineering quantum devices for the implementation of topologically protected quantum bits describe…
