Optical cooling of atoms in microtraps by time-delayed reflection
Peter Horak, André Xuereb, Tim Freegarde
We present a theoretical analysis of a novel scheme for optical cooling of particles that does not in principle require a closed optical transition. A tightly confined laser beam i…
Scattering theory of multilevel atoms interacting with arbitrary radiation fields
André Xuereb, Peter Domokos, Peter Horak +1
We present a generic transfer matrix approach for the description of the interaction of atoms possessing multiple ground state and excited state sublevels with light fields. This m…
Stimulated Raman transitions via multiple atomic levels
James Bateman, André Xuereb, Tim Freegarde
We consider the stimulated Raman transition between two long-lived states via multiple intermediate states, such as between hyperfine ground states in the alkali-metal atoms. We pr…
Scattering theory of cooling and heating in opto-mechanical systems
André Xuereb, Peter Domokos, János Asbóth +2
We present a one-dimensional scattering theory which enables us to describe a wealth of effects arising from the coupling of the motional degree of freedom of scatterers to the ele…
Mirror-mediated cooling: a paradigm for particle cooling via the retarded dipole force
Tim Freegarde, James Bateman, André Xuereb +1
Cooling forces result from the retarded dipole interaction between an illuminated particle and its reflection. For a one-dimensional example, we find cooling times of milliseconds…
Atom cooling using the dipole force of a single retroreflected laser beam
André Xuereb, Peter Horak, Tim Freegarde
We present a mechanism for cooling atoms by a laser beam reflected from a single mirror. The cooling relies on the dipole force and thus in principle applies to arbitrary refractiv…
