Effect of the Magnus force on skyrmion relaxation dynamics
(Amer Physical Soc, 2018-01-10)
Systematic scaling in the low-energy excitations of the t-J model in one and two dimensions
(American Physical Society, 1997-05-01)
We present an exact diagonalization study of the low-energy singlet and triplet states for both the one-dimensional (1D) and 2D t-J models. A scan of the parameter ratio J/t shows that for most low-energy states in both ...
Measurement by antilocalization of interactions between InAs surface electrons and magnetic surface species
(American Physical Society, 2013-02-25)
We show that antilocalization measurements can be used to experimentally study the interactions between InAs surface electrons and local moments of the rare earth ions Sm3+, Gd3+, and Ho3+ on the surface. Magnetic spin-flip ...
Pole versus Breit-Wigner resonance description of the orbitally excited baryons
(American Physical Society, 1999-06)
We consider the masses used in recent studies involving the nonstrange sector of the l = 1 baryons. The use of T-matrix and K-matrix poles versus the conventional Breit-Wigner masses is discussed within the context of a ...
Measurement of the neutron beta-asymmetry parameter A(0) with ultracold neutrons
(American Physical Society, 2012-11-12)
We present a detailed report of a measurement of the neutron beta-asymmetry parameter A(0), the parity-violating angular correlation between the neutron spin and the decay electron momentum, performed with polarized ultracold ...
First measurement of the muon antineutrino double-differential charged-current quasielastic cross section
(American Physical Society, 2013-08-02)
The largest sample ever recorded of (nu) over bar (mu) charged-current quasielastic (CCQE, (nu) over bar (mu) + p -> mu(+) + n) candidate events is used to produce the minimally model-dependent, flux-integrated double-differential ...
Lagrangian and energy forms for retrieving the impulse response of the Earth due to random electromagnetic forcing
(American Physical Society, 2011-08-10)
We distinguish between trivial and nontrivial differences in retrieving the real or imaginary parts of the Green's function. Trivial differences come from different Green's function definitions. The energy and Lagrangian ...
Entrainment and Unit Velocity: Surprises in an Accelerated Exclusion Process
(American Physical Society, 2012-09-27)
We introduce a class of distance-dependent interactions in an accelerated exclusion process inspired by the observation of transcribing RNA polymerase speeding up when "pushed" by a trailing one. On a ring, the accelerated ...
Nonequilibrium Relaxation and Critical Aging for Driven Ising Lattice Gases
(American Physical Society, 2012-03-13)
We employ Monte Carlo simulations to study the nonequilibrium relaxation of driven Ising lattice gases in two dimensions. Whereas the temporal scaling of the density autocorrelation function in the nonequilibrium steady ...
Three-Point Functions of Aging Dynamics and the AdS-CFT Correspondence
(American Physical Society, 2012-09-28)
Aging can be realized as a subalgebra of Schrodinger algebra by discarding the time-translation generator. While the two-point functions of the age algebra have been known for some time, little else was known about the ...
