We investigate spectral properties of a fermion coupled with a massive gauge boson with a mass
m at finite temperature (T ) in the perturbation theory.

Running Spectral Index Inflation Modulations

2010/12/27
We argue that a large negative running spectral index, if confirmed, might suggest that there are abundant structures in the inflaton potential, which result in a fairly large (both positive and negat...

We give a sufficient condition for discreteness of the spectrum for supersymmmetric and non supersymmetric theories with a fermionic contribution. Our approach allows the analysis of the complete redu...
Failure of t-J models in describing doping evolution of spectral weight in x-ray scattering, optical and photoemission spectra of the cuprates

2010/11/19
We have analyzed experimental evidence for an anomalous transfer of spectral weight from high
to low energy scales in both electron and hole doped cuprates as a function of doping. X-ray
