Giant Proximity Effect and Coupling in Superfluid
نویسندگان
چکیده
Previous measurements of the specific heat of helium-4 (4He) confined in all three spatial dimensions suggested a coupling between neighbor ing confinements through the tiny channels used to fill them [1]. Measurements of the superfluid fraction in the filling channels also suggested an enhancement attributed to their proximity to the larger regions of superfluid [1]. Recent measurements of confinement structures designed at the Cornell NanoScale Science and Technology Facility have confirmed these effects [2], and begun to address their nature.

Weak Coupling of Superfluid Helium Confined to Zero Dimensions
Measurements of the specific heat of liquid helium confined in all three spatial dimensions shows an anomalous behavior that suggests a coupling of individual regions of superfluid. This coupling is thought to occur through the shallow channels used to fill the boxes used as confinement structures. This may be evidence of a proximity effect where helium in the larger boxes modifies the behavior...

متن کاملStrong-coupling expansion for ultracold bosons in an optical lattice at finite temperatures in the presence of superfluidity
We develop a strong-coupling (t U ) expansion technique for calculating the density profile for bosonic atoms trapped in an optical lattice with an overall harmonic trap at finite temperature and finite on-site interaction in the presence of superfluid regions. Our results match well with quantum Monte Carlo simulations at finite temperature. We also show that the superfluid order parameter nev...
متن کاملRelativistic Coulomb excitation within the time dependent superfluid local density approximation.
Within the framework of the unrestricted time-dependent density functional theory, we present for the first time an analysis of the relativistic Coulomb excitation of the heavy deformed open shell nucleus (238)U. The approach is based on the superfluid local density approximation formulated on a spatial lattice that can take into account coupling to the continuum, enabling self-consistent studi...
متن کاملRenormalized HVBK dynamics for Superfluid Helium Turbulence
We review the Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations for superfluid Helium turbulence and discuss their implications for recent measurements of superfluid turbulence decay. A new Hamiltonian formulation of these equations renormalizes the vortex line velocity to incorporate finite temperature effects. These effects also renormalize the coupling constant in the mutual friction force ...
