Condensed-matter physics: Optical lattices

  title={Condensed-matter physics: Optical lattices},
  author={Markus Greiner and Simon F{\"o}lling},
Optical lattices have rapidly become a favoured tool of atomic and condensed-matter physicists. These crystals made of light can be used to trap atoms at very low temperatures, creating a workshop in which to pore over and tinker with fundamental properties of matter. 

Condensed-matter physics: Paralysed by disorder

In a disordered medium, a quantum particle can literally stop itself in its tracks and be observed directly using the coldest known form of matter, caught in a laser trap.

Obtaining the phase diagram and thermodynamic quantities of bulk systems from the densities of trapped gases

A long-standing goal of experiments using cold atoms in optical lattices is to simulate the behaviour of strongly correlated electrons in solid-state systems. However, in these experiments, the atoms

Perturbative approach to three-component fermionic atoms in optical lattices

We develop a perturbative approach combined with the dynamical mean-field theory for investigating the Mott transition in repulsively interacting three-component fermionic atoms in optical lattices.

Ultracold atoms in optical lattice

In the seminar, physical principles underlying behavior of atoms in optical lattices are presented. Optical lattice is formed by the interference of counter-propagating laser beams, which creates

The Bose-Hubbard model with disorder in low-dimensional lattices

Tunneling of Atoms, Nuclei and Molecules

This is a brief review of few relevant topics on tunneling of composite particles and how the coupling to intrinsic and external degrees of freedom affects tunneling probabilities. I discuss the

Coherent control of dressed matter waves.

It is demonstrated experimentally that matter waves can be coherently and adiabatically loaded and controlled in one-, two-, and three-dimensional strongly driven optical lattices, paving the way for studies of driven quantum systems and new methods for controlling matter waves.

Tunable disorder in a crystal of cold polar molecules

We show that a two-species mixture of polar molecules trapped on an optical lattice gives rise to a system of rotational excitons in the presence of tunable impurities. The exciton-impurity

Optical lattice emulator: How to construct it and what can it do

Recently, many laboratories around the world are using cold atoms in optical lattices to emulate theoretical models for strongly correlated systems in condensed matter physics. There are great

Cooling ultracold bosons in optical lattices by spectral transform

It is shown theoretically how to directly obtain the energy distribution of a weakly interacting gas of bosons confined in an optical lattice in the tight-binding limit. This is accomplished by
