Functional Renormalization Group Flows and Gauge Consistency in QED
Yoshio Echigo, Yuji Igarashi, Katsumi Itoh +2
We consider quantum electrodynamics with chiral four-Fermi interactions in the functional renormalization group approach. In gauge theories, the functional flow equation for the ef…
Addendum: Long-range multi-scalar models at three loops
Dario Benedetti, Razvan Gurau, Sabine Harribey
We correct the computation of one Feynman diagram in the three-loop beta functions for the long-range quartic multi-scalar model, originally presented in (2020 J. Phys. A: Math. Th…
Stabilizing massless fields with fluxes in Landau-Ginzburg models
Katrin Becker, Muthusamy Rajaguru, Anindya Sengupta +2
Recent work on flux compactifications suggests that the tadpole constraint generically allows only a limited number of complex structure moduli to become massive, i.e., be stabiliz…
Finite-size versus finite-temperature effects in the critical long-range model
Dario Benedetti, Razvan Gurau, Sabine Harribey +1
In this paper we consider classical and quantum versions of the critical long-range model, for which we study finite-size and finite-temperature effects, respectively, at la…
Duality of Orthogonal and Symplectic Random Tensor Models: General Invariants
Hannes Keppler, Thomas Muller
In Gurau and Keppler 2022 (arXiv:2207.01993), a relation between orthogonal and symplectic tensor models with quartic interactions was proven. In this paper, we provide an alternat…
To Half--Be or Not To Be?
Claudia de Rham, Sebastian Garcia-Saenz, Lavinia Heisenberg +2
It has recently been argued that half degrees of freedom could emerge in Lorentz and parity invariant field theories, using a non-linear Proca field theory dubbed Proca-Nuevo as a…
