Total current blockade in an ultracold dipolar quantum wire.

چکیده
Cold-atom systems offer a great potential for the future design of new mesoscopic quantum systems with properties that are fundamentally different from semiconductor nanostructures. Here, we investigate the quantum-gas analogue of a quantum wire and find a new scenario for the quantum transport: Attractive interactions may lead to a complete suppression of current in the low-bias range, a total current blockade. We demonstrate this effect for the example of ultracold quantum gases with dipolar interactions.

A dipolar gas of ultracold molecules.
Ultracold polar molecular gases promise new directions and exciting applications in collisions and chemical reactions at ultralow energies, precision measurements, novel quantum phase transitions, and quantum information science. Here we briefly discuss key experimental requirements for observing strong dipole-dipole interactions in an ultracold dipolar gas of molecules. We then survey current ...
متن کاملThe physics of dipolar bosonic quantum gases
This article reviews the recent theoretical and experimental advances in the study of ultracold gases made of bosonic particles interacting via the longrange, anisotropic dipole-dipole interaction, in addition to the short-range and isotropic contact interaction usually at work in ultracold gases. The specific properties emerging from the dipolar interaction are emphasized, from the meanfield r...
متن کاملFractional quantum Hall states in ultracold rapidly rotating dipolar fermi gases.
We demonstrate the experimental feasibility of incompressible fractional quantum Hall-like states in ultracold two-dimensional rapidly rotating dipolar Fermi gases. In particular, we argue that the state of the system at filling fraction nu = 1/3 is well described by the Laughlin wave function and find a substantial energy gap in the quasiparticle excitation spectrum. Dipolar gases, therefore, ...
متن کاملElectrostatic Trapping of Ultracold Polar Molecules
This thesis describes the progress made in the production, spectroscopic characterization, and confinement of ultracold, polar NaCs molecules. A two-species magneto-optical trap (MOT) for the simultaneous cooling and trapping of sodium and cesium atoms is utilized for the creation of ultracold NaCs molecules via photoassociation. The molecules are detected via resonance-enhanced multi-photon io...
متن کاملNonequilibrium dynamics of an ultracold dipolar gas
We study the relaxation and damping dynamics of an ultracold, but not quantum degenerate, gas consisting of dipolar particles. These simulations are performed using a direct simulation Monte Carlo method and employing the highly anisotropic differential cross section of dipoles in the Wigner threshold regime. We find that both cross-dimensional relaxation and damping of breathing modes occur at...
