Engineering momentum profiles of cold-atom beams
D Hudson Smith, Artem G Volosniev
We describe a procedure for engineering beams of cold atoms by selectively draining particles from a trapped gas based on momenta. Atoms escape through a filter potential that only…
Impenetrability in Floquet scattering in one dimension
A. G. Volosniev, D. H. Smith
We study the scattering off a time-periodic zero-range potential in one spatial dimension. We focus on the parameter regions that lead to zero-transmission probability (ZTP). For s…
Dynamics of small trapped one-dimensional Fermi gas under oscillating magnetic fields
X. Y. Yin, Yangqian Yan, D. Hudson Smith
Deterministic preparation of an ultracold harmonically trapped one-dimensional Fermi gas consisting of a few fermions has been realized by the Heidelberg group. Using Floquet forma…
Induced two-body scattering resonances from a square-well potential with oscillating depth
D. H. Smith
In systems of ultracold atoms, pairwise interactions can be resonantly enhanced by a new mechanism which does not rely upon a magnetic Feshbach resonance. In this mechanism, intera…
Inducing Resonant Interactions in Ultracold Atoms with a Modulated Magnetic Field
D. Hudson Smith
In systems of ultracold atoms, pairwise interactions can be resonantly enhanced by a new mechanism which does not rely upon a magnetic Feshbach resonance. In this mechanism, intera…
Association of Atoms into Universal Dimers using an Oscillating Magnetic Field
Christian Langmack, D. Hudson Smith, Eric Braaten
In a system of ultracold atoms near a Feshbach resonance, pairs of atoms can be associated into universal dimers by an oscillating magnetic field with frequency near that determine…
Selection Rules for Hadronic Transitions of XYZ Mesons
Eric Braaten, Christian Langmack, D. Hudson Smith
Many of the XYZ mesons discovered in the last decade can be identified as bound states of a heavy quark and antiquark in Born-Oppenheimer (B-O) potentials defined by the energy of…
Two-body and Three-body Contacts for Identical Bosons near Unitarity
D. Hudson Smith, Eric Braaten, Daekyoung Kang +1
In a recent experiment with ultracold trapped Rb-85 atoms, Makotyn et al. have studied a quantum-degenerate Bose gas in the unitary limit where its scattering length is infinitely…
Observation of Entanglement-Dependent Two-Particle Holonomic Phase
J. C. Loredo, M. A. Broome, D. H. Smith +1
Holonomic phases---geometric and topological---have long been an intriguing aspect of physics. They are ubiquitous, ranging from observations in particle physics to applications in…
Avalanche Mechanism for the Enhanced Loss of Ultracold Atoms
Christian Langmack, D. Hudson Smith, Eric Braaten
In several experiments with ultracold trapped atoms, a narrow loss feature has been observed near an {\it atom-dimer resonance}, at which there is an Efimov trimer at the atom-dime…
The Avalanche Mechanism for Atom Loss near an Atom-Dimer Efimov Resonance
Christian Langmack, D. Hudson Smith, Eric Braaten
An Efimov trimer near the atom-dimer threshold can increase the atom loss rate in ultracold trapped atoms through the {\it avalanche mechanism} proposed by Zaccanti et al. A 3-body…
