Self-organized criticality in a relativistic Yukawa theory with Luttinger fermions
Holger Gies, Marta Picciau
We propose and investigate a Yukawa model featuring a dynamical scalar field coupled to relativistic Luttinger fermions. Using the functional renormalization group (RG) as well as…
Phase transition analogs in laser collisions with a dark-field setup
Holger Gies, Felix Karbstein, Lars Maiwald
Laser pulse collisions are a promising tool for the investigation of light-by-light scattering phenomena induced by quantum vacuum fluctuations. Using the numerical code based on t…
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…
Fermionic Fixed-Point Structure of Asymptotically Safe QED with a Pauli Term
Holger Gies, Kevin K. K. Tam
We test the physical viability of a recent proposal for an asymptotically safe modification of quantum electrodynamics (QED), whose ultraviolet physics is dominated by a non-pertur…
Quantum field theories of relativistic Luttinger fermions
Holger Gies, Philip Heinzel, Johannes Laufkötter +1
We propose relativistic Luttinger fermions as a new ingredient for the construction of fundamental quantum field theories. We construct the corresponding Clifford algebra and the s…
Particle self-bunching in the Schwinger effect in spacetime-dependent electric fields
Florian Hebenstreit, Reinhard Alkofer, Holger Gies
Non-perturbative electron-positron pair creation (Schwinger effect) is studied based on the equal-time Wigner formalism in 1+1 dimensions. An ab initio calculation of the Schwinger…
