Thermal Phase Fluctuations in Narrow Superfluid Rings
Parth Sabharwal, Daniel G. Allman, Pradipta Debnath +1
Using matter-wave interference, we have investigated thermal phase fluctuations in narrow coplanar, concentric rings of ultracold fermionic superfluids. We found that the correlati…
Quench-induced spontaneous currents in rings of ultracold fermionic atoms
Daniel G. Allman, Parth Sabharwal, Kevin C. Wright
We have observed the spontaneous appearance of currents in a ring of ultracold fermionic atoms (6Li) with attractive interactions, following a quench to a BCS-like pair superfluid.…
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…
