Spinor Bose gases form a family of quantum fluids manifesting both magnetic order and<?
format?> superfluidity. This article reviews experimental and theoretical progress in …

Originally, the Hubbard model was derived for describing the behavior of strongly correlated
electrons in solids. However, for over a decade now, variations of it have also routinely been …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

Compass models are theories of matter in which the couplings between the internal spin (or
other relevant field) components are inherently spatially (typically, direction) dependent. A …

We study the ground states of cold atoms in the tight-binding bands built from p orbitals on a
two dimensional honeycomb optical lattice. The band structure includes two completely flat …

The successful emulation of the Hubbard model in optical lattices has stimulated extensive
efforts to extend their scope to also capture more complex, incompletely understood …

Ultracold atoms trapped by light offer robust quantum coherence and controllability,
providing an attractive system for quantum information processing and for the simulation of …

Optical lattices have an important role in advancing our understandingof correlated quantum
matter. The recent implementation of orbital degrees of freedom in chequerboard, and …

We report on the realization of a multiorbital system with ultracold atoms in the excited bands
of a 3D optical lattice by selectively controlling the band population along a given lattice …

We study the ground-state properties of the interacting spinless fermions in the px, y-orbital
bands in the two-dimensional honeycomb optical lattice, which exhibit different features from …
