CosmoLattice: A modern code for lattice simulations of scalar and gauge field dynamics in an expanding universe
Daniel Garcia Figueroa, Adrien Florio, Wessel Valkenburg, Francisco Torrenti
This paper describes CosmoGattice, a modern package for lattice simulations of the dynamics of interacting scalar and gauge fields in an expanding universe. CosmoGattice incorporates a series of features that makes it very versatile and powerful: i) it is ...
ELSEVIER2023Universality of loop corrected soft theorems in 4d
In [1], logarithmic correction to subleading soft photon and soft graviton theorems have been derived in four spacetime dimensions from the ratio of IR-finite S-matrices. This has been achieved after factoring out IR-divergent components from the tradition ...
New York2023The art of simulating the early universe. Part I. Integration techniques and canonical cases
Daniel Garcia Figueroa, Adrien Florio, Wessel Valkenburg, Francisco Torrenti
We present a comprehensive discussion on lattice techniques for the simulation of scalar and gauge field dynamics in an expanding universe. After reviewing the continuum formulation of scalar and gauge field interactions in Minkowski and FLRW backgrounds, ...
2021Aspects of Gauge Theories Vacua
This thesis is concerned with gauge theories, their complicated vacuum and resulting effects. After an introduction to the subject, it is divided into four parts.
Firstly, we treat the problem of chiral charge dynamics at finite temperature. Quantum field ...
EPFL2020Goldstone equivalence and high energy electroweak physics
Andrea Wulzer, Gabriel Francisco Cuomo, Luca Vecchi
The transition between the broken and unbroken phases of massive gauge theories, namely the rearrangement of longitudinal and Goldstone degrees of freedom that occurs at high energy, is not manifestly smooth in the standard formalism. The lack of smoothnes ...
