Light-induced collisions of ultracold rubidium atoms
In this dissertation I present a variety of experiments on collisions between ultra-cold rubidium atoms. These collisions take place in light-force atom traps, where temperatures below 1 mK are reached. At these low temperatures weak, long-range interactions between the atoms are important, and collision times are long. Consequently, the absorption and spontaneous emission of photons plays an i...
متن کاملLight-induced gauge fields for ultracold atoms.
Gauge fields are central in our modern understanding of physics at all scales. At the highest energy scales known, the microscopic universe is governed by particles interacting with each other through the exchange of gauge bosons. At the largest length scales, our Universe is ruled by gravity, whose gauge structure suggests the existence of a particle-the graviton-that mediates the gravitationa...

متن کاملManipulating scattering of ultracold atoms with light-induced dissipation
*Correspondence: Mikhail Lemeshko, ITAMP, Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, MS-14, Cambridge, MA 02138, USA e-mail: mikhail.lemeshko@ gmail.com Recently it has been shown that pairs of atoms can form metastable bonds due to non-conservative forces induced by dissipation [Lemeshko and Weimer, Nature Comm. 4, 2230 (2013)]. Here we study the dynamics of interaction-ind...
متن کاملStrong saturation absorption imaging of dense clouds of ultracold atoms.
We report on a far above saturation absorption imaging technique to investigate the characteristics of dense packets of ultracold atoms. The transparency of the cloud is controlled by the incident light intensity as a result of the nonlinear response of the atoms to the probe beam. We detail our experimental procedure to calibrate the imaging system for reliable quantitative measurements and de...
