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.
Spectral properties of quarks above the critical temperature for deconfinement are analyzed in quenched lattice QCD on lattices of size 128^3x16. We study quark spectral function in energy and momentu...

We present a new method to calculate meson spectral functions (SPFs) on the lattice based on a variational method. Because, on a finite volume lattice, the meson SPFs have discrete spectra only, a sui...

In this paper we examine the relevance of the signature of the metric of space-time on constructing the product of the pseudo-Riemannian spectral triple with a finite triple describing the internal ge...
Duality violations in tau hadronic spectral moments     Duality violations  tau hadronic spectral moments       font style='font-size:12px;'> 2011/1/7
Evidence is presented for the necessity of including duality violations in a consistent description of spectral function moments employed in the precision determination of $\alpha_s$ from $\tau$ decay...
Running Spectral Index from Inflation with Modulations     Running Spectral Index  Inflation  Modulations       font style='font-size:12px;'> 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 study the properties of charmonium states at finite temperature in quenched QCD on isotropic lattices. We measured charmonium correlators using non-perturbatively $\cO(a)$ improved clover fermions ...
Spectral properties in supersymmetric matrix models     Spectral properties  supersymmetric matrix models       font style='font-size:12px;'> 2010/12/24
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...
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 scattering,...
Supersymmetry and PT-Symmetric Spectral Bifurcation     Supersymmetry  Spectral Bifurcation  Quantum Physics       font style='font-size:12px;'> 2010/11/8
Dynamical systems exhibiting both PT and Supersymmetry are analyzed in a general scenario. It is found that, in an appropriate parameter domain, the ground state may or may not respect PT-symmetry. In...
We present a new method to calculate meson spectral functions (SPFs) on the lattice based on a variational method. Because, on a finite volume lattice, the meson SPFs have discrete spectra only, a s...

Evidence is presented for the necessity of including duality violations in a consistent description of spectral function moments employed in the precision determination of s from  decay. A physicall...
We study the properties of charmonium states at finite temperature in quenched QCD on isotropic lattices.
