RG Dynamics of Irrelevant Fermion Operators and the Drag Coupling Mechanism
Jeremias Aguilera-Damia, Diego Rodriguez-Gomez, Jorge Russo
We study the renormalization-group flow of higher-dimensional fermionic interactions in the presence of a Fermi surface. We show that the growth of the BCS f…
Black holes and causal nonlinear electrodynamics
Jorge G. Russo, Paul K. Townsend
For generic theories of nonlinear electrodynamics (NLED) we investigate the implications of (a)causality on spherically-symmetric solutions of the Einstein-NLED equations that are…
Simplified self-dual electrodynamics
Jorge G. Russo, Paul K. Townsend
We present a new formulation of self-dual nonlinear electrodynamics in which interactions are determined by an auxiliary-field potential, with causality ensuring a unique solution…
More on phase transitions in = 2 massive gauge theories
Jeremias Aguilera Damia, Jorge G. Russo
We study large phase transitions in theories with gauge group and massive hypermultiplets in diverse representations. Using supersymmetric localization…
Causal chiral 2-form electrodynamics
Jorge G. Russo, Paul K. Townsend
Generic nonlinear theories of chiral 2-form electrodynamics allow superluminal propagation in some stationary homogeneous backgrounds and are therefore acausal. We find a simple pa…
