Quantum-limited mass flow of liquid $^{3}$He (2008)
Lambert, G., Gervais, G., Mullin, W. J.
We consider theoretically the possibility of observing unusual quantum fluid behavior in liquid $^{3}$He and solutions of $^{3}$He in $^{4}$He systems confined to nano-channels. In the case of pure...
Giant viscosity enhancement in a spin-polarized Fermi liquid (2007)
Akimoto, H., Xia, J. S., Candela, D., Mullin, W. J., Adams, E. D., Sullivan, N. S.
The viscosity is measured for a Fermi liquid, a dilute $^3$He-$^4$He mixture, under extremely high magnetic field/temperature conditions ($B \leq 14.8$ T, $T \geq 1.5$ mK). The spin splitting energy...
Mullin, W. J., Krotkov, R., Laloë, F.
Additional variables (also often called ``hidden variables'') are sometimes added to standard quantum mechanics in order to remove its indeterminism or ``incompletness,'' and to make the measurement...

Spin Diffusion in Trapped Gases: Anisotropy in Dipole and Quadrupole Modes (2006)
Recent experiments in a mixture of two hyperfine states of trapped Bose gases show behavior analogous to a spin-1/2 system, including transverse spin waves and other familiar Leggett-Rice-type...

The origin of phase in the interference of Bose-Einstein condensates (2006)
Mullin, W. J., Krotkov, R., Laloë, F.
We consider the interference of two overlapping ideal Bose-Einstein condensates. The usual description of this phenomenon involves the introduction of a so-called condensate wave functions having a...

Landau Damping of Spin Waves in Trapped Boltzmann Gases (2005)
Ragan, R. J., Mullin, W. J., Wiita, E. B.
A semiclassical method is used to study Landau damping of transverse pseudo-spin waves in harmonically trapped ultracold gases in the collisionless Boltzmann limit. In this approach, the time...
Anisotropic Spin Diffusion in Trapped Boltzmann Gases (2004)
Recent experiments in a mixture of two hyperfine states of trapped Bose gases show behavior analogous to a spin-1/2 system, including transverse spin waves and other familiar Leggett-Rice-type...
Quantum Statistics: Is there an effective fermion repulsion or boson attraction? (2003)
Physicists often claim that there is an effective repulsion between fermions, implied by the Pauli principle, and a corresponding effective attraction between bosons. We examine the origins of such...
Bose-Einstein Condensation, Fluctuations, and Recurrence Relations in Statistical Mechanics (2002)
Mullin, W. J., Fernández, J. P.
We calculate certain features of Bose-Einstein condensation in the ideal gas by using recurrence relations for the partition function. The grand canonical ensemble gives inaccurate results for...
New Evidence for Zero-Temperature Relaxation in a Spin-Polarized Fermi Liquid (2002)
Akimoto, H., Candela, D., Xia, J. S., Mullin, W. J., Adams, E. D., Sullivan, N. S.
Spin-echo experiments are reported for 3He-4He solutions under extremely high B/T conditions, B=14.75 T and T >= 1.73 mK. The 3He concentration x_3 was adjusted close to the value x_c = 3.8% at which...
Mullin, W. J., Holzmann, M., Laloe, F.
Several authors have considered the possibility of a generalized Bose-Einstein condensation (BEC) in which a band of low states is occupied so that the total occupation number is macroscopic, even if...
Instability in a Two-Dimensional Dilute Interacting Bose System (2000)
Mullin, W. J., Holzmann, M., Laloe, F.
The formalism of Ursell operators provides a self-consistent integral equation for the one-particle reduced operator. In three dimensions this technique yields values of the shift in the...
Bose-Einstein Condensation in a Harmonic Potential (1996)
We examine several features of Bose-Einstein condensation (BEC) in an external harmonic potential well. In the thermodynamic limit, there is a phase transition to a spatial Bose-Einstein condensed...
