Storage and Adiabatic Cooling of Polar Molecules in a Microstructured Trap
adiabatic cooling cold molecules electrostatic trapping
2011/8/17
Abstract: We demonstrate loading, trapping and adiabatic cooling of polar molecules in a new type of electric trap. The trap consists of two microstructured capacitor plates with an additional perimet...

Tunable Superfluidity Quantum Magnetism Ultracold Polar Molecules
2011/9/13
By selecting two dressed rotational states of ultracold polar molecules in an optical lattice, we obtain a highly tunable generalization of the t-J model, which we refer to as the t-J-V -W model. In a...
We show that dipolar interactions between ultracold polar alkali dimers in optical lattices can be used to realize a highly tunable generalization of the t-J model, which we refer to as the t-J-V -W m...
The Prediction of a Gapless Topological "Haldane Liquid" Phase in a One-Dimensional Cold Polar Molecular Lattice
Prediction of a Gapless One-Dimensional Cold Polar Molecular Lattice
2010/11/19
We show that ultracold two-component fermionic dipolar gases in an optical lattice with strong
two-body on-site loss can be used to realize a tunable effective spin-one model.
Contribution of interband effects caused by long-wavelength transverse optical phonons to electron-phonon coupling in doped polar insulators
Contribution of interband effects electron-phonon coupling doped polar insulators
2010/11/22
We estimate the contribution of the long-wavelength el–TO–ph interaction and discuss the effect it has on electron pairing in doped polar systems like SrTiO3 and PbTe. The analytical and numerical res...
Tunable exciton-phonon interactions in an optical lattice of polar molecules
Tunable exciton-phonon interactions optical lattice polar molecules
2010/11/11
We show that an ensemble of polar molecules trapped in an optical lattice can be considered as a controllable open quantum system. The coupling between collective rotational excitations and the center...
