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
TLDR
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. Expand
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 atomsExpand
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.Expand
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 createsExpand

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 theExpand
A quantum gas of polar molecules in an optical lattice
The production of molecules from dual species atomic quantum gases has enabled experiments that employ molecules at nanoKelvin temperatures. As a result, every degree of freedom of these molecules isExpand
Coherent control of dressed matter waves.
TLDR
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. Expand
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-impurityExpand
