Correlated atomic wires on substrates. II. Application to Hubbard wires
Anas Abdelwahab, Eric Jeckelmann, Martin Hohenadler
In the first part of our theoretical study of correlated atomic wires on substrates, we introduced lattice models for a one-dimensional quantum wire on a three-dimensional substrat…
Correlated atomic wires on substrates. I. Mapping to quasi-one-dimensional models
Anas Abdelwahab, Eric Jeckelmann, Martin Hohenadler
We present a theoretical study of correlated atomic wires deposited on substrates in two parts. In this first part, we propose lattice models for a one-dimensional quantum wire on…
Luttinger Liquid Physics and Spin-Flip Scattering on Helical Edges
M. Hohenadler, F. F. Assaad
We investigate electronic correlation effects on edge states of quantum spin-Hall insulators within the Kane-Mele-Hubbard model by means of quantum Monte Carlo simulations. Given t…
Polariton Mott insulator with trapped ions or circuit QED
M. Hohenadler, M. Aichhorn, L. Pollet +1
We consider variants of the Jaynes-Cummings-Hubbard model of lattice polaritons, taking into account next-nearest-neighbor, diagonal and long-range photon hopping in one and two di…
Quantum Phase Transitions in Bosonic Heteronuclear Pairing Hamiltonians
M. Hohenadler, A. O. Silver, M. J. Bhaseen +1
We explore the phase diagram of two-component bosons with Feshbach resonant pairing interactions in an optical lattice. It has been shown in previous work to exhibit a rich variety…
Feshbach Resonance in Optical Lattices and the Quantum Ising Model
M. J. Bhaseen, A. O. Silver, M. Hohenadler +1
Motivated by experiments on heteronuclear Feshbach resonances in Bose mixtures, we investigate s-wave pairing of two species of bosons in an optical lattice. The zero temperature p…
