Leading low-temperature correction to the Heisenberg-Euler Lagrangian

Felix Karbstein

In this note, we show that the well-known leading low-temperature correction to the Heisenberg-Euler Lagrangian in a constant electromagnetic field arising at two loops can be effi…

The -vacuum from functional renormalisation

Yuepeng Guan, Jan M. Pawlowski, Masatoshi Yamada

We study topological properties of a quantum mechanical system with -symmetry within the functional renormalisation group (fRG) approach. These properties include the vacuum…

Hamiltonian Neural Networks approach to fuzzball geodesics

Andrea Cipriani, Alessandro De Santis, Giorgio Di Russo +2

The recent increase in computational resources and data availability has led to a significant rise in the use of Machine Learning (ML) techniques for data analysis in physics. Howe…

Mean-field theory for self-interacting relativistic Luttinger fermions

Holger Gies, Marta Picciau

We investigate a class of quantum field theories with relativistic Luttinger fermions and local self-interaction in scalar channels. For an understanding of possible low-energy pha…

Renormalization Flow of Nonlinear Electrodynamics

Holger Gies, Julian Schirrmeister

We study the renormalization flow of generic actions that depend on the invariants of the field strength tensor of an abelian gauge field. While the Maxwell action defines a Gaussi…

Towards the full Heisenberg-Euler effective action at large

Felix Karbstein

We study the Heisenberg-Euler effective action in constant electromagnetic fields for QED with charged particle flavors of the same mass and charge in the large $…
