Specific-heat discontinuity in impure two-band superconductors
(American Physical Society, 2003)
The Ginzburg-Landau coefficients and the jump of the specific heat are calculated for a disordered two-band superconductor. We start with the analysis of a more general case with arbitrary anisotropy. While the specific-heat ...
Controllable optical switch using a Bose-Einstein condensate in an optical cavity
(American Physical Society, 2011)
The optical bistability of an ultracold atomic ensemble located in a small-volume ultrahigh-finesse optical cavity is investigated. We find that a transverse pumping field can be used to control the bistable behavior of ...
Spectra and magnetic properties of large spins in external fields
(American Physical Society, 1999)
Spectra and magnetic properties of large spins J (e.g., spins possessed by ions or molecules), placed into a crystal electric field (CEF) of an arbitrary symmetry point group, are shown to change drastically when J changes ...
P(t) Dependence of Transverse Flow in Relativistic Heavy-Ion Collisions
(American Physical Society, 1996)
The strength of transverse flow is examined as a function of transverse momentum p(t) using a simple, transversely moving thermal model and a more realistic, relativistic transport model. It is shown that the p(t) dependence ...
Landau-Zener transitions in a linear chain
(American Physical Society, 2002)
We present an exact asymptotic solution for electron transition amplitudes in an infinite linear chain driven by an external time-dependent electric field. This solution extends the Landau-Zener theory for the case of an ...
Critical behavior and universality in Levy spin glasses
(American Physical Society, 2011)
Using large-scale Monte Carlo simulations that combine parallel tempering with specialized cluster updates, we show that Ising spin glasses with Levy-distributed interactions share the same universality class as Ising spin ...
High-energy behavior of the nuclear symmetry potential in asymmetric nuclear matter RID A-2398-2009
(American Physical Society, 2005)
Using the relativistic impulse approximation with empirical NN scattering amplitude and the nuclear scalar and vector densities from the relativistic mean-field theory, we evaluate the Dirac optical potential for neutrons ...
Simple Heuristic Derivation of the Universal Jump in the Superfluid Density of 2-Dimensional Superfluids
(American Physical Society, 1992)
A simple heuristic derivation is given for the universal jump in the superfluid density rho(s) at the transition temperature T(c) of a two-dimensional superfluid. It is based on the mathematical equivalence of the Hamiltonians ...
Transverse-momentum dependent modification of dynamic texture in central Au+Au collisions at root s(NN)=200 GeV RID B-7517-2009
(American Physical Society, 2005)
Correlations in the hadron distributions produced in relativistic Au+Au collisions are studied in the discrete wavelet expansion method. The analysis is performed in the space of pseudorapidity (vertical bar eta vertical ...
K+ production in baryon-baryon and heavy-ion collisions
(American Physical Society, 1998)
Kaon production cross sections in nucleon-nucleon, nucleon-Delta, and Delta-Delta interactions are studied in a boson exchange model. For the latter two interactions, the exchanged pion can be on-mass shell
