Spin Gradient Demagnetization Cooling of Ultracold Atoms
, 2011 We demonstrate a new cooling method in which a time-varying magnetic field gradient is applied to an ultracold spin mixture. This enables preparation of isolated spin distributions at positive and negative effective spin temperatures of ±50 pK.

QUANTUM REFLECTION AND THE INTERACTIONS OF ULTRACOLD ATOMS WITH SURFACES AND NANOSTRUCTURES
Momento, 2011 Quantum reflection refers to the reflection of particles by attractive long-range potentials in nonclassical regions of coordinate space without reaching a classical turning point.

Direct Frequency Comb Laser Cooling and Trapping
Physical Review X, 2016 Ultracold atoms, produced by laser cooling and trapping, have led to recent advances in quantum information, quantum chemistry, and quantum sensors. A lack of ultraviolet narrow-band lasers precludes laser cooling of prevalent atoms such as hydrogen ...

A C0(_2) laser lattice experiment for cold atoms [PDF]
, 2007 This thesis presents work on a laser cooling experiment designed for trapping Rb atoms in a CO(_2) laser optical trap. Some emphasis is placed on experimental features designed to allow the future implementation of a neutral atom quantum computation ...

Quantum simulation of conductivity plateaux and fractional quantum Hall effect using ultracold atoms
New Journal of Physics, 2015 We analyze the role of impurities in the fractional quantum Hall effect using a highly controllable system of ultracold atoms. We investigate the mechanism responsible for the formation of plateaux in the resistivity/conductivity as a function of the ...

A cold strontium Rydberg gas [PDF]
, 2011 Cold gases of Rydberg atoms are an ideal system in which to study the novel effects of strong interatomic interactions. This thesis describes the design and construction of the world's first experiment to study Rydberg states in a cold gas of an alkaline

Cavity-controlled formation of ultracold molecules
New Journal of Physics, 2018 Ultracold ground-state molecules can be formed from ultracold atoms via photoassociation followed by a spontaneous emission process. Typically, the molecular products are distributed over a range of final states. Here, we propose to use an optical cavity
