Theory and it ab initio calculation of radiative lifetime of excitons in semiconducting carbon nanotubes

, 2005
We present theoretical analysis and first-principles calculation of the radiative lifetime of excitons in semiconducting carbon nanotubes. An intrinsic lifetime of the order of 10 ps is computed for the lowest optically active bright excitons.

Family of solvable generalized random-matrix ensembles with unitary symmetry

, 2005
We construct a very general family of characteristic functions describing Random Matrix Ensembles (RME) having a global unitary invariance, and containing an arbitrary, one-variable probability measure which we characterize by a `spread function ...

Painleve IV and degenerate Gaussian Unitary Ensembles

, 2006
We consider those Gaussian Unitary Ensembles where the eigenvalues have prescribed multiplicities, and obtain joint probability density for the eigenvalues.

Decay of Correlations in Fermi Systems at Non-zero Temperature

, 2004
The locality of correlation functions is considered for Fermi systems at non-zero temperature. We show that for all short-range, lattice Hamiltonians, the correlation function of any two fermionic operators decays exponentially with a correlation length ...

The Pitfalls of Dark Crossings

, 2013
We explore the connection between pair production of dark matter particles at collider experiments and annihilation of dark matter in the early and late universe, with a focus on the correlation between the two time-reversed processes. We consider both a
