Spontaneous conformal symmetry breaking in fishnet CFT

open access: yesPhysics Letters B, 2020
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

Spontaneous symmetry breaking from an on-shell perspective

open access: yesJournal of High Energy Physics
We show how the well known patterns of masses and interactions that arise from spontaneous symmetry breaking can be determined from an entirely on-shell perspective, that is, without reference to Lagrangians, gauge symmetries, or fields acquiring a ...

Spontaneous Symmetry Breaking as the Mechanism of Quantum Measurement [PDF]

open access: yesarXiv, 1994
It is proposed that an event that constitutes a quantum measurement corresponds to the spontaneous breaking of a symmetry in the measuring device over time.

Leptogenesis from spontaneous symmetry breaking during inflation

open access: yesJournal of High Energy Physics, 2019
Symmetry breaking in the Higgs field via a non-minimal coupling to gravity or higher-dimensional interactions with the inflaton can lead to condensation at a large vacuum expectation value (VEV) during inflation.

Gravitational Entropy and the Second Law of Thermodynamics

open access: yesEntropy, 2015
The spontaneous violation of Lorentz and diffeomorphism invariance in a phase near the big bang lowers the entropy, allowing for an arrow of time and the second law of thermodynamics. The spontaneous symmetry breaking leads to
