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 ...
Semiclassical framework for the calculation of transport anisotropies
(American Physical Society, 2009)
We present a procedure for finding the exact solution to the linear-response Boltzmann equation for two-dimensional anisotropic systems and demonstrate it on examples of noncrystalline anisotropic magnetoresistance in a ...
Short-time-evolved wave functions for solving quantum many-body problems
(American Physical Society, 2003)
The exact ground state of a strongly interacting quantum many-body system can be obtained by evolving a trial state with finite overlap with the ground state to infinite imaginary time. In many cases, since the convergence ...
Impurity-induced local density of states in a d-wave superconductor carrying a supercurrent
(American Physical Society, 2005)
The local density of states (LDOS) and its Fourier component induced by a unitary impurity in a supercurrent-carrying d-wave superconductor are investigated. Both of these quantities possess a reflection symmetry about the ...
Hybrid skew scattering regime of the anomalous Hall effect in Rashba systems: Unifying Keldysh, Boltzmann, and Kubo formalisms RID B-3617-2008
(American Physical Society, 2008)
We present the analytical description of the anomalous Hall effect (AHE) in a two-dimensional electron gas (2DEG) ferromagnet within the Keldysh formalism. These results unify the three linear-response approaches to AHE ...
Impurity-induced configuration-transition in the Fulde-Ferrell-Larkin-Ovchinnikov state of a d-wave superconductor
(American Physical Society, 2007)
The effect of impurities on Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states in a layered superconductor with d-wave pairing symmetry is investigated using the tight-binding model and the Bogoliubov-de Gennes equations. At ...
Pentaquark Theta(+) production from the reaction gamma p ->pi K-+(-)Theta(+)
(American Physical Society, 2004)
The cross section for theta(+) production from the reaction gammap-->pi(+)K(-)theta(+), which was observed in the CLAS experiment at the Jefferson National Laboratory, is evaluated in a hadronic model that includes couplings ...
Quantum search protocol for an atomic array
(American Physical Society, 2001)
Quantum computers can, in principle, exceed the speed of ordinary computers by taking advantage of quantum coherence and entanglement. It is possible to find a "needle in a haystack" of N-1 straws in only rootN searches ...
Anisotropic transport properties of ferromagnetic-superconducting bilayers
(American Physical Society, 2004)
We study the transport properties of vortex matter in a superconducting thin film separated by a thin insulator layer from a ferromagnetic layer. We assume an alternating stripe structure for both FM and superconducting ...
Multiphase transport model for relativistic nuclear collisions
(American Physical Society, 2000)
To study heavy ion collisions at energies available from the Relativistic Heavy Ion Collider (RHIC), we have developed a multiphase transport model that includes both initial partonic and final hadronic interactions. ...
