Spontaneous symmetry breaking and ghost states supported by the fractional PT-symmetric saturable nonlinear Schrödinger equation. [PDF]

open access: yesChaos, 2022
We report a novel spontaneous symmetry breaking phenomenon and ghost states existed in the framework of the fractional nonlinear Schrödinger equation with focusing saturable nonlinearity and PT-symmetric potential.

Bound of diffusion constants from pole-skipping points: spontaneous symmetry breaking and magnetic field [PDF]

open access: yesJournal of High Energy Physics, 2021
We investigate the properties of pole-skipping of the sound channel in which the translational symmetry is broken explicitly or spontaneously. For this purpose, we analyze, in detail, not only the holographic axion model, but also the magnetically ...

Spontaneous time-reversal symmetry breaking in twisted double bilayer graphene [PDF]

open access: yesNature Communications, 2022
Twisted double bilayer graphene (tDBG) comprises two Bernal-stacked bilayer graphene sheets with a twist between them. Gate voltages applied to top and back gates of a tDBG device tune both the flatness and topology of the electronic bands, enabling an ...

Entanglement and spontaneous symmetry breaking in quantum spin models [PDF]

open access: green, 2003
It is shown that spontaneous symmetry breaking does not modify the ground-state entanglement of two spins, as defined by the concurrence, in the XXZ- and the transverse field Ising-chain.

Spontaneously broken subsystem symmetries

open access: yesJournal of High Energy Physics, 2022
We investigate the spontaneous breaking of subsystem symmetries directly in the context of continuum field theories by calculating the correlation function of charged operators. Our methods confirm the lack of spontaneous symmetry breaking in some of the

Multi-stage spontaneous symmetry breaking of light in Kerr ring resonators

open access: yesCommunications Physics, 2023
Spontaneous symmetry breaking of light in ring resonators are of broad interest due to its fundamental properties in nonlinear optics and its potential applications in photonic circuits and optical communications.

Tunneling potentials for the tunneling action: gauge invariance

open access: yesJournal of High Energy Physics, 2022
We formulate a procedure to obtain a gauge-invariant tunneling rate at zero temperature using the recently developed tunneling potential approach. This procedure relies on a consistent power counting in gauge coupling and a derivative expansion.

Dilaton in scalar QFT: a no-go theorem in 4-epsilon and 3-epsilon dimensions

open access: yesSciPost Physics, 2022
Spontaneous scale invariance breaking and the associated Goldstone boson, the dilaton, is investigated in renormalizable, unitary, interacting non-supersymmetric scalar field theories in $4-\varepsilon$ dimensions.

Radiative Corrections as the Origin of Spontaneous Symmetry Breaking [PDF]

open access: yes, 1973
We investigate the possibility that radiative corrections may produce spontaneous symmetry breakdown in theories for which the semiclassical (tree) approximation does not indicate such breakdown.
