Higher-Order Fermion Interactions in Effective Field Theories for Phase Transitions
Diego Rodriguez-Gomez, Jorge G. Russo
We investigate the impact of higher-order fermionic deformations in phase transitions analogous to those described by the Bardeen-Cooper-Schrieffer (BCS) theory. Focusing specifica…
Defects, Rigid Holography and -theorems
I. Carreño Bolla, Diego Rodriguez-Gomez, J. G. Russo
We consider a general scalar QFT with a linear defect in and a surface defect in . Using holography and the Hamilton-Jacobi formalism, we show that the functions…
New exact solutions in multi-scalar field cosmology
Jorge G. Russo
We use the method of the superpotential to derive exact solutions describing inflationary cosmologies in multi-field models. An example that describes a solution that interpolates…
RG Flows and Stability in Defect Field Theories
I. Carreño Bolla, D. Rodriguez-Gomez, J. G. Russo
We investigate defects in scalar field theories in four and six dimensions in a double-scaling (semiclassical) limit, where bulk loops are suppressed and quantum effects come from…
Nonlinear Electrodynamics without Birefringence
Jorge G. Russo, Paul K. Townsend
All solutions of the no-birefringence conditions for nonlinear electrodynamics are found. In addition to the known Born-Infeld and Plebanski cases, we find a ``reverse Born-Infeld'…
Defects in scalar field theories, RG flows and Dimensional Disentangling
D. Rodriguez-Gomez, J. G. Russo
We consider defect operators in scalar field theories in dimensions and with self-interactions given by a general marginal potential. In a double scaling limit, whe…
