Interplay of Chiral Transitions in the Standard Model
Holger Gies, Richard Schmieden, Luca Zambelli
We investigate nonperturbative aspects of the interplay of chiral transitions in the standard model in the course of the renormalization flow. We focus on the chiral symmetry break…
Pauli-Term-Induced Fixed Points in -dimensional QED
Holger Gies, Kevin K. K. Tam, Jobst Ziebell
We explore the fixed-point structure of QED-like theories upon the inclusion of a Pauli spin-field coupling. We concentrate on the fate of UV-stable fixed points recently discovere…
Asymptotically Safe Hilbert-Palatini Gravity in an On-Shell Reduction Scheme
Holger Gies, Abdol Sabor Salek
We study the renormalization flow of Hilbert-Palatini gravity to lowest non-trivial order. We find evidence for an asymptotically safe high-energy completion based on the existence…
All-optical Quantum Vacuum Signals in Two-Beam Collision
Holger Gies, Felix Karbstein, Leonhard Klar
The fundamental theory of quantum electrodynamics predicts the vacuum to resemble a polarizable medium. This gives rise to effective nonlinear interactions between electromagnetic…
Background Effective Action with Nonlinear Massive Gauge Fixing
Holger Gies, Dimitrios Gkiatas, Luca Zambelli
We combine a recent construction of a BRST-invariant, nonlinear massive gauge fixing with the background field formalism. The resulting generating functional preserves background-f…
Exploring new states of matter with a photonic emulator
Felix Karbstein, Simon Stützer, Holger Gies +1
We implement the equation of motion of the large-N Gross-Neveu model from strong interaction physics in photonic waveguide arrays and study one of its paradigmatic multi-fermion bo…
