چکیده

We propose and analyze a technique that allows one to suppress inelastic collisions and simultaneously enhance elastic interactions between cold polar molecules. The main idea is to cancel the leading dipole-dipole interaction with a suitable combination of static electric and microwave fields in such a way that the remaining van der Waals-type potential forms a three-dimensional repulsive shield. We analyze the elastic and inelastic scattering cross sections relevant for evaporative cooling of polar molecules and discuss the prospect for the creation of stable crystalline structures.

Atomic Rydberg reservoirs for polar molecules.

We discuss laser-dressed dipolar and van der Waals interactions between atoms and polar molecules, so that a cold atomic gas with laser admixed Rydberg levels acts as a designed reservoir for both elastic and inelastic collisional processes. The elastic scattering channel is characterized by large elastic scattering cross sections and repulsive shields to protect from close encounter collisions...

Influence of magnetic fields on cold collisions of polar molecules

We consider cold collisions of OH molecules in the P3/2 ground state, under the influence of a magnetic field. We find that modest fields of several thousand gauss can act to suppress inelastic collisions of weakfield-seeking states by two orders of magnitude. We attribute this suppression to two factors: sid an indirect coupling of the entrance and the exit channel, in contrast to the effect o...

Controlling the quantum stereodynamics of ultracold bimolecular reactions

Molecular collisions in the quantum regime represent a new opportunity to explore chemical reactions. Recently, atom-exchange reactions were observed in a trapped ultracold gas of KRb molecules. In an external electric field, these polar molecules can easily be oriented and the exothermic and barrierless bimolecular reactions, KRb + KRb → K2 + Rb2, occur at a rate that rises steeply with increa...

Novel Systems and Methods for Quantum Communication, Quantum Computation, and Quantum Simulation

Precise control over quantum systems can enable the realization of fascinating applications such as powerful computers, secure communication devices, and simulators that can elucidate the physics of complex condensed matter systems. However, the fragility of quantum effects makes it very difficult to harness the power of quantum mechanics. In this thesis, we present novel systems and tools for ...

Recent Advances in Calculating Molecular Collision Rates

Interstellar clouds are mainly composed of hydrogen molecules whose molecular spectra are difficult to record. Major other components are polar molecules, whose rotational and ro-vibrational spectra are readily observed. Inelastic collisions of molecules with H2 and electrons are important processes to understand the formation and intensities of molecular spectral lines. We have calculated the ...
