Effective Long-Range Interactions in Confined Curved Dimensions
Effective Long-Range Interactions Confined Curved Dimensions Quantum Gases
2011/8/4
Abstract: We explore the effective long-range interaction of charged particles confined to a curved low-dimensional manifold using the example of a helical geometry. Opposite to the Coulomb interactio...
Three-body exclusion principle, duality mapping, and exact ground state of a harmonically trapped, ultracold Bose gas with three-body hard-core interactions in one dimension
duality mapping exact ground state of a harmonically trapped ultracold Bose gas with three-body hard-core interactions
2010/11/19
Motivated by previous suggestions that three-body hard-core interactions in lower-dimensional
ultracold Bose gases might provide a way for creation of non-Abelian anyons, the exact ground
state of a...
Strong Interactions of Single Atoms and Photons near a Dielectric Boundary
Interactions Single Atoms Dielectric Boundary
2010/11/8
Modern research in optical physics has achieved quantum control of strong interactions between a single atom and one photon within the setting of cavity quantum electrodynamics (cQED). However, to mov...
Confinement-induced p-wave resonances from s-wave interactions
Confinement-induced p-wave resonances s-wave interactions
2011/1/7
We show that a purely s-wave interaction in three dimensions (3D) can induce higher partialwave
resonances in mixed dimensions. We develop two-body scattering theories in all three cases of
0D-3D.
Constraints on anomalous spin-spin interactions from spin-exchange collisions
Constraints anomalous spin-spin interactions spin-exchange collisions
2010/11/11
Measured and calculated cross sections for spin-exchange between alkali atoms and noble gases (specifically sodium and helium) are used to constrain anomalous spin-dependent forces between nuclei at t...

A Remark on One-Dimensional Many-Body Problems with Point Interactions
Remark One-Dimensional Many-Body Problems Point Interactions
2010/10/15
The integrability of one dimensional quantum mechanical many-body problems with general contact interactions is extensively studied. It is shown that besides the pure (repulsive or attractive) δ-funct...
