We provide a pedagogical review article on fundamentals and applications of the quantum
dynamics in strong electromagnetic fields in QED and QCD. The fundamentals include the …

These introductory notes are about functional renormalization group equations and some of
their applications. It is emphasised that the applicability of this method extends well beyond …

I present a pedagogical review of Heisenberg–Euler effective Lagrangians, beginning with
the original work of Heisenberg and Euler, and Weisskopf, for the one loop effective action of …

We show that domains are formed in a homogeneous SU (2) color magnetic field. Due to
quantum fluctuations the domains have fluid properties. It is then argued that, quantum …

A bstract Based on the recent success of the Angantyr model in describing multiplicity
distributions of the hadronic final state in high energy heavy ion collisions, we investigate …

It is shown that a quantum state consisting of a condensate of color magnetic flux tubes is
formed in QCD for a rather weak coupling g 2/4π= 0.37. This result is obtained in a …

It is shown that there exists a very close analogy between a lattice of vortices in a
superconductor near the critical field and a condensate of color magnetic flux tubes due to …

We study field theory models in the context of a gravitational theory without the cosmological
constant problem (CCP). The theory is based on the requirement that the measure of …

This book introduces a rapidly growing new research area? the study of dynamical
properties of elementary fields. The methods used in this field range from algebraic topology …

We employ nonperturbative flow equations for an investigation of the effective action in Yang-
Mills theories. We compute the effective action Γ [B] for constant color magnetic fields B and …
