Cesium atoms shaken, not stirred, to create elusive excitation in superfluid
Cesium atoms shaken not stirred elusive excitation superfluid
2015/3/4
Scientists discovered in 1937 that liquid helium-4, when chilled to extremely low temperatures, became a superfluid that could leak through glass, overflow its containers, or eternally gush like ...
Phase transitions in a three dimensional U(1)×U(1) lattice London superconductor: Metallic superfluid and charge-4e superconducting states
Three dimensional lattice superconductor condensation coupling pulse measurement the current current coupling
2014/12/18
We consider a three dimensional lattice U(1)×U(1) and [U(1)]N superconductors in the London limit with individually conserved condensates. The U(1)×U(1) problem, generically, has two types of intercom...

Grey solitons strongly interacting superfluid Fermi Gas
2010/11/24
The Bardeen-Cooper-Schrieffer to Bose-Einstein condensate (BCS to BEC) crossover problem is
solved for stationary grey solitons via the Boguliubov-de Gennes equations at zero temperature.
These cros...
A Spectroscopic Method to Measure the Superfluid Fraction of an Ultracold Atomic Gas

The weak magnetic field induced reduction of the low-temperature superfluid density in cuprate
superconductors is studied based on the kinetic energy driven superconducting mechanism. The
electromag...

We study the instability of a superfluid flow through a constriction in three spatial dimensions.We consider a Bose-Einstein condensate at zero temperature in two different geometries: a straight wave...
Low-temperature thermodynamics of the unitary Fermi gas: superfluid fraction, first sound and second sound
Low-temperature thermodynamics of the unitary Fermi gas superfluid fraction first sound second sound
2011/1/10
We investigate the low-temperature thermodynamics of the unitary Fermi gas by introducing a
model based on the zero-temperature spectra of both bosonic collective modes and fermonic singleparticle ex...
We study two different types of simplified models for Kelvin wave turbulence on quantized vortex lines in superfluids near zero temperature. Our first model is obtained from a truncated expansion of t...
