Universality 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 York2023CosmoLattice: 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 ...
ELSEVIER2023General invariance and equilibrium conditions for lattice dynamics in 1D, 2D, and 3D materials
Nicola Marzari, Changpeng Lin, Samuel Poncé
The long-wavelength behavior of vibrational modes plays a central role in carrier transport, phonon-assisted optical properties, superconductivity, and thermomechanical and thermoelectric properties of materials. Here, we present general invariance and equ ...
NATURE PORTFOLIO2022Magnetogenesis in Higgs-Starobinsky inflation
In the framework of mixed Higgs-Starobinsky inflation, we consider the generation of Abelian gauge fields due to their nonminimal coupling to gravity (in two different formulations of gravity-metric and Palatini). We couple the gauge-field invariants F mu ...
2022Gravitational causality and the self-stress of photons
Brando Bellazzini, Giulia Isabella
We study causality in gravitational systems beyond the classical limit. Using on-shell methods, we consider the 1-loop corrections from charged particles to the photon energy-momentum tensor - the self-stress - that controls the quantum interaction between ...
2022Gauge Equivariant Neural Networks for Quantum Lattice Gauge Theories
Gauge symmetries play a key role in physics appearing in areas such as quantum field theories of the fundamental particles and emergent degrees of freedom in quantum materials. Motivated by the desire to efficiently simulate many-body quantum systems with ...
AMER PHYSICAL SOC2021The 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, ...
2021Goldstone 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 ...
2020Aspects 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 ...
EPFL2020Spontaneous conformal symmetry breaking in fishnet CFT
Quantum field theories with exact but spontaneously broken conformal invariance have an intriguing feature: their vacuum energy (cosmological constant) is equal to zero. Up to now, the only known ultraviolet complete theories where conformal symmetry can b ...
