Landau model for films and interfaces of superfluid 4HE at T=OK
… a Landau theory appropriate to an inhomogeneous superfluid at temperature T = 0 to describe structural and dynamical effects at a gas/superfluid interface and for a superfluid film on an inert attractive substrate. The parameters of the theory are determined phenomenologically by fitting measured …

Neutron electric dipole moment and dressed spin
… a novel technique of ultra-cold neutrons(UCN) in superfluid 4He at the Spallation Neutron Source (SNS) at the Oak Ridge National Laboratory (ORNL). In the experiment, 3He in the measurement cell will be used as a neutron spin analyzer and a comagnetometer. The absorption between UCN and 3He atoms …

Transport of 3He for the nEDM experiment at the SNS
… cm}. This experiment utilizes polarized 3He in superfluid 4He to detect neutron precession in a 30 mG magnetic field and 75 kV/cm electric field via the spin dependent reaction \mathrm{n}\mathrm{+^{3}He}\rightarrow\mathrm{p}\mathrm{+^{3}H}+764\mathrm{\,KeV}. Polarized 3He is produced by an …

Quantum turbulence generated by moving grids
… grid turbulence produced by moving grids within superfluid 4He, both at millikelvin temperatures, with an oscillating grid, and at temperatures above 1.4 K with a linearly moving grid. Floppy devices were used at millikelvin temperatures to produce quantum turbulence. We investigated the …
