Functional Renormalization Group Analysis of Nonlinear Sigma Model and Non-Abelian Bosonization Duality
Junichi Haruna, Keito Shimizu, Masatoshi Yamada
It is known that the Wess-Zumino-Witten model is dual to the free fermion theory in two dimensions via non-Abelian bosonization. While it is decomposed into the Wess…

Gradient Flow Exact Renormalization Group for Scalar Quantum Electrodynamics
Junichi Haruna, Masatoshi Yamada
Gradient Flow Exact Renormalization Group (GF-ERG) is a framework to define the renormalization group flow of Wilsonian effective action utilizing coarse-graining along the diffusi…

Nonperturbative aspects of two-dimensional -deformed scalar theory from functional renormalization group
Jie Liu, Junichi Haruna, Masatoshi Yamada
We study -deformed scalar field theory in two-dimensional spacetime using the functional renormalization group. We derive the functions for the couplings in th…
