Spectral Function of Fermion Coupled with Massive Vector Boson at Finite Temperature in Gauge Invariant Formalism
Spectral Function of Fermion Coupled Massive Vector Boson Finite Temperature Gauge Invariant Formalism
2011/1/10
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.
Two-point generating function of the free energy for a directed polymer in a random medium
Directed polymer Lieb-Liniger Bose gas Kardar-Parisi-Zhang equation
2010/11/24
We consider a 1+1 dimensional directed continuum polymer in a Gaussian delta-correlated space-time random potential. For this model the moments (= replica)of the partition function, Z(x, t), can be ex...
