Inhomogeneous Broadening and the Kosterlitz-Thouless Transition
(American Physical Society, 1993)
Torsional-oscillator studies of very thin He-4 films have found nonuniversal behavior of the superfluid response as a function of coverage. The temperature width of the superfluid transition region is nonmonotonic in the ...
Thermopower of Yba2cu3o7-X, Erba2cu3o7-X
(American Physical Society, 1990)
Phase-Boundary of a Cubic Superconducting Circuit in a Magnetic-Field of Arbitrary Magnitude and Direction
(American Physical Society, 1991)
An exact analytic expression for the mean-field phase boundary T(c)(H) of a cubic superconducting circuit in an arbitrary external-magnetic-field vector H is derived. The phase boundary of this circuit is shown to depend ...
Response of GaAs to fast intense laser pulses
(American Physical Society, 1998)
Motivated by recent experiments, we have performed simulations which show in detail how the electrons and ions in GaAs respond to fast intense laser pulses (with durations of order 100 fs and intensities of order 1-10 ...
Theory of first-order layering transitions in thin helium films
(American Physical Society, 1996)
Thin liquid He-4 films on graphite show evidence of layered growth with increasing number density via a succession of first-order phase transitions. These so-called ''layering transitions'' separate uniformly covering ...
Astrophysical S factor for Be-9(p,gamma)B-10
(American Physical Society, 1999)
The Be-9(p, gamma) B-10 reaction plays an important role in primordial and stellar nucleosynthesis of light elements in the p shell, but the energy dependence of S(E) has not been well understood. We reanalyze the existing ...

Asymptotic normalization coefficients for C-13+p -> N-14
(American Physical Society, 1998)
The C-13(N-14,C-13)N-14 proton exchange reaction has been measured at an incident energy of 162 MeV. Angular distributions were obtained for proton transfer to the ground and low-lying excited states in N-14. Elastic ...
Transport and superconducting properties of RNi2B2C (R=Y, Lu) single crystals
(American Physical Society, 1997)
The in-plane resistivity, in-plane absolute thermopower, and upper critical held measurements are reported for single-crystal samples of YNi2B2C and LuNi2B2C superconductors. The in-plane resistivity shows metallic behavior ...
Theory of the hysteresis loop in ferromagnets
(American Physical Society, 1999)
We consider three mechanisms of hysteresis phenomena in alternating magnetic field: the domain-wall motion in a random medium, the nucleation, and the retardation of magnetization due to slow (critical) fluctuations. We ...
