A Lorentzian Gribov no-pole condition for Yang-Mills theory
M. S. Guimaraes
For over four decades, Gribov's no-pole condition has been almost exclusively explored in Euclidean space, where the elliptic nature of the Faddeev-Popov operator provides a clear…
Heterotic Warm Inflation
Arjun Berera, Heliudson Bernardo, Suddhasattwa Brahma +3
We propose a two-field model of warm inflation motivated by a heterotic string construction, involving an axion and a dilaton-like scalar field with non-trivial kinetic mixing. Gau…
Investigating the Araki-Uhlmann relative entropy between two coherent states in relativistic Quantum Field Theory
João G. A. Caribé, Marcelo S. Guimaraes, Itzhak Roditi +1
A numerical setup for investigating the Araki-Uhlmann relative entropy between two coherent states is presented for a scalar massive Quantum Field Theory in ()-dimensional Min…
Revisiting the Abelian super Stueckelberg model
M. A. L. Capri, D. R. Granado, I. F. Justo +1
The Abelian super Stueckelberg model (ASSM) in the Wess--Zumino (WZ) gauge is revisited, and the actual set of supersymmetric (SUSY) transformation is derived. In particular, we ve…
Warming up the Fibres
Dibya Chakraborty, Rudnei O. Ramos
Fibre inflationary models are constructed in type-IIB string flux compactification. These models have been shown to be in agreement with the cosmological observations under appropr…
Relative entropy of single-mode squeezed states in Quantum Field Theory
Marcelo S. Guimaraes, Itzhak Roditi, Silvio P. Sorella +1
Utilizing the Tomita-Takesaki modular theory, we derive a closed-form analytic expression for the Araki-Uhlmann relative entropy between a single-mode squeezed state and the vacuum…
