Generalized Exclusion Statistics in the Kondo Problem
We consider the generalized exclusion statistics in the Kondo problem. The
thermodynamic Bethe ansatz equations have been used for a multicomponent system
of particles obeying the generalized exclusion principle. We have found a
relation between the derivative of the phase shift of the scattering matrix for
Fermi particles and for particles characterized by generalized exclusion
statistics. We show that the statistical matrix in the Kondo problem has a
universal form in high and low temperature limits.Comment: 15 pages Sabj-class: Strongly Correlated Electron
Nonlocal Edge State Transport in Topological Insulators
We use the N-terminal scheme for studying the edge state transportin in
two-dimensional topological insulators. We find the universal nonlocal response
in the ballistic transport approach. This macroscopic exhibition of the
topological order offers different areas for applications.Comment: Updated to published versio
Energy Bounds of Linked Vortex States
Energy bounds of knotted and linked vortex states in a charged two-component
system are considered. It is shown that a set of local minima of free energy
contains new classes of universality. When the mutual linking number of vector
order parameter vortex lines is less than the Hopf invariant, these states have
lower-lying energies.Comment: 4 pages, Latex2
Chern-Simons Correlations on (2+1)D Lattice
We have computed the contribution of zero modes to the value of the number of
particles in the model of discrete (2+1)-dimensional nonlinear Schr\"odinger
equation. It is shown for the first time that in the region of small values of
the Chern-Simons coefficient k there exists a universal attraction between
field configurations. For k=2 this phenomenon may be a dynamic origin of the
semion pairing in high temperature superconducting state of planar systems.Comment: 9 pages, 2 figures Sabj-class: Strongly Correlated Electron
Radiogenic and Muon-Induced Backgrounds in the LUX Dark Matter Detector
The Large Underground Xenon (LUX) dark matter experiment aims to detect rare
low-energy interactions from Weakly Interacting Massive Particles (WIMPs). The
radiogenic backgrounds in the LUX detector have been measured and compared with
Monte Carlo simulation. Measurements of LUX high-energy data have provided
direct constraints on all background sources contributing to the background
model. The expected background rate from the background model for the 85.3 day
WIMP search run is
~events~keV~kg~day
in a 118~kg fiducial volume. The observed background rate is
~events~keV~kg~day,
consistent with model projections. The expectation for the radiogenic
background in a subsequent one-year run is presented.Comment: 18 pages, 12 figures / 17 images, submitted to Astropart. Phy
