Spectral Representation at Finite Temperature
Sourav Sarkar, B. K. Patra, V. J. Menon +1
This is a short review on the thermal, spectral representation in the real-time version of the finite temperature quantum field theory. After presenting a clear derivation of the s…

On the Non-Orthonormality of Lippmann-Schwinger-Low States
V. J. Menon, B. K. Patra
It is pointed out that for a general short-ranged potential the Lippmann-Schwinger-Low scattering state does not strictly satisfy the Schrodinger eigen equation, and the…

Baryon Number Penetrability as a Measure of Isothermal Baryon Number Fluctuations in the Early Universe
B. K. Patra, V. J. Menon, C. P. Singh
We have examined the efficiency of baryon-number transport mechanism across the phase boundary in a cosmological quark-hadron phase transition through the proper estimate of baryon…
