Towards the Parametric Renormalization of the S-matrix -- I
Pinaki Banerjee, Harsh, Alok Laddha
Zimmermann's forest formula is the corner stone of perturbative renormalization in QFT. By renormalizing individual Feynman graphs, it generates the UV finite S-matrix. This approa…

Phase Thermalization: from Fermi Liquid to Incoherent Metal
Pinaki Banerjee, Bidisha Chakrabarty, Swapnamay Mondal
When a system consists of a large subsystem (bath) and a small one (probe), thermalization implies induction of temperature of the bath onto the probe. If both the bath and the pro…
