Functional Renormalization Group

Statistical Approach to Quantum Field Theory, 2021
The functional renormalization group is a particular implementation of the renormalization group concept which combines functional methods of quantum field theory with the renormalization group idea of Kenneth Wilson. It interpolates smoothly between the known microscopic laws and the complex macroscopic phenomena in physical systems.

Pseudo-fermion functional renormalization group with magnetic fields

Physical review B, 2023
The pseudo-fermion functional renormalization group is generalized to treat spin Hamiltonians with finite magnetic fields, enabling its application to arbitrary spin lattice models with linear and bilinear terms in the spin operators.

Optimization and stabilization of functional renormalization group flows

Physical Review D
We revisit optimization of functional renormalization group flows by analyzing regularized loop integrals. This leads us to a principle, the , and a corresponding order relation which allows us to order existing regularization schemes with respect to the
