Competition between multiple totally asymmetric simple exclusion processes for a finite pool of resources
(American Physical Society, 2009-09)
Using Monte Carlo simulations and a domain-wall theory, we discuss the effect of coupling several totally asymmetric simple exclusion processes (TASEPs) to a finite reservoir of particles. This simple model mimics directed ...
Microscopic study of the 2/5 fractional quantum Hall edge
(American Physical Society, 2011-12-09)
This paper reports on our study of the edge of the 2/5 fractional quantum Hall state, which is more complicated than the edge of the 1/3 state because of the presence of edge sectors corresponding to different partitions ...

Case eigenfunction expansion for a conservative medium
(AIP Publishing, 1976-02)
By using the resolvent integration technique introduced by Larsen and Habetler, the one‐speed, isotropic scattering,neutron transport equation is treated in the infinite and semi‐infinite media. It is seen that the results ...
t-J model studied by the power Lanczos method
(American Physical Society, 1995-03)
The initial trial wave function used in a simple ground-state projection method, the power method, is systematically improved by using Lanczos algorithm. Much faster convergence to the ground state achieved by using these ...
Wave scattering in one dimension with absorption
(AIP Publishing, 1998-04)
Wave scattering is analyzed in a one-dimensional nonconservative medium governed by the generalized Schrodinger equation d(2) psi/dx(2)+k(2) psi=[ikP(x)+Q(x)]psi, where P(x) and Q(x) are real, integrable potentials with ...
Diagnostics of AGN-driven molecular outflows in ULIRGs from Herschel-PACS observations of OH at 119 μm
(IOP Publishing Ltd., 2013-10)
We report on our observations of the 79 and 119 mu m doublet transitions of OH for 24 local (z < 0.262) ULIRGs observed with Herschel-PACS as part of the Herschel ULIRG Survey (HERUS). Some OH 119 mu m profiles display a ...
A unifying model for Neoproterozoic–Palaeozoic exceptional fossil preservation through pyritization and carbonaceous compression
Soft-tissue fossils capture exquisite biological detail and provide our clearest views onto the rise of animals across the Ediacaran–Cambrian transition. The processes contributing to fossilization of soft tissues, however, ...
Resonant Raman-active acoustic phonons in ion-implanted GaAs
(American Physical Society, 1988-09)
We have observed a new, strong feature at 47 cm-1 in the first-order Raman spectrum of ion-implanted GaAs, prior to any anneal. It is not present in the Raman spectrum of either amorphous or single-crystal GaAs. The peak ...
Pyramidal and toroidal water drops after impact on a solid surface
(Cambridge University Press, 2003-06)
Superhydrophobic surfaces generate very high contact angles as a result of their microstructure. The impact of a water drop on such a surface shows unusual features, such as total rebound at low impact speed. We report ...
