Mitigating Heating of Degenerate Fermions in a Ring-Dimple Atomic Trap
Daniel G. Allman, Parth Sabharwal, Kevin C. Wright
We report on the impact of the extended geometry of a ring-dimple trap on particle loss heating of a degenerate Fermi gas. When the Fermi level is slightly greater than the depth o…
Persistent currents in rings of ultracold fermionic atoms
Yanping Cai, Daniel G. Allman, Parth Sabharwal +1
We have produced persistent currents of ultracold fermionic atoms trapped in a ring, with lifetimes greater than 10 seconds in the strongly-interacting regime. These currents remai…
Monolithic bowtie cavity traps for ultra-cold gases
Yanping Cai, Daniel Allman, Jesse Evans +2
We report on trapping and cooling Li-6 atoms in a monolithic ring bowtie cavity. To make the cavity insensitive to magnetic fields used to tune atomic interactions, we constructed…
Topology, edge states, and zero-energy states of ultracold atoms in 1D optical superlattices with alternating onsite potentials or hopping coefficients
Yan He, Kevin Wright, Said Kouachi +1
One-dimensional superlattices with periodic spatial modulations of onsite potentials or tunneling coefficients can exhibit a variety of properties associated with topology or symme…
Protocols for dynamically probing topological edge states and dimerization with fermionic atoms in optical potentials
Mekena Metcalf, Chen-Yen Lai, Kevin Wright +1
Topological behavior has been observed in quantum systems including ultracold atoms. However, background harmonic traps for cold-atoms hinder direct detection of topological edge s…
Threshold for creating excitations in a stirred superfluid ring
K. C. Wright, R. B. Blakestad, C. J. Lobb +2
We have measured the threshold for creating long-lived excitations when a toroidal Bose-Einstein condensate is stirred by a rotating (optical) barrier of variable height. When the…
