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 ...
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 ...
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 ...
Charged particle rapidity distributions at relativistic energies
(American Physical Society, 2001)
Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
Low-temperature magnetization of (Ga,Mn) As semiconductors
(American Physical Society, 2006)
We report on a comprehensive study of the ferromagnetic moment per Mn atom in (Ga,Mn)As ferromagnetic semiconductors. Theoretical discussion is based on microscopic calculations and on an effective model of Mn local moments ...
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 ...
Probing the softest region of the nuclear equation of state
(American Physical Society, 1998)
An attractive, energy-dependent mean-field potential for baryons is introduced in order to generate a soft region in the nuclear equation of state, as suggested by recent lattice QCD calculations of baryon-free matter at ...
Tests of transfer reaction determinations of astrophysical S factors
(American Physical Society, 1999)
The O-16(He-3,d)F-17 reaction has been used to determine asymptotic normalization coefficients for transitions to the ground and first excited states of F-17. Th, coefficients provide the normalization for the tails of the ...
Hadronic scattering of charmed mesons
(American Physical Society, 2000)
The scattering cross sections of charm mesons with hadrons such as the pion, rho meson, and nucleon are studied in an effective Lagrangian. In heavy ion collisions, rescattering of produced charm mesons by hadrons affects ...
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 ...
