Entanglement and Spontaneous Symmetry Breaking in Quantum Spin Models [PDF]

Phys. Rev. A 68, 060301 (2003), 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. Correlation function inequalities, valid in any dimensions for these models, are presented outlining the regimes where entanglement is unaffected by spontaneous ...

Spontaneous symmetry breaking of dissipative optical solitons in a two-component Kerr resonator [PDF]

Nature Communications, 2021
Dissipative solitons and their symmetry breaking is important for photonic applications. Here the authors show that dissipative solitons can undergo spontaneous symmetry breaking in a two-component nonlinear optical ring resonator, resulting in the ...

Entanglement-enabled symmetry-breaking orders [PDF]

SciPost Physics Core, 2022
A spontaneous symmetry-breaking order is conventionally described by a tensor-product wavefunction of some few-body clusters; some standard examples include the simplest ferromagnets and valence bond solids. We discuss a type of symmetry-breaking orders,

A zero-mode mechanism for spontaneous symmetry breaking in a turbulent von Kármán flow [PDF]

New Journal of Physics, 2014
We suggest that the dynamical spontaneous symmetry breaking reported in a turbulent swirling flow at Re  = 40 000 by Cortet et al (2010 Phys. Rev. Lett. 105 214501) can be described through a continuous one parameter family transformation (amounting to a

Spontaneous symmetry-breaking in optomechanical cavity [PDF]

Phys. Rev. A 101, 063813 (2020), 2019
A theoretical consideration of the so-called "membrane-in-the-middle" optomechanical cavity revealed that it undergoes a spontaneous symmetry breaking as a function of the transparency of the membrane. Such typical features of this phenomenon as a square-root development of the order parameter and divergency of the critical susceptibility were ...

A holographic perspective on phonons and pseudo-phonons [PDF]

Journal of High Energy Physics, 2017
We analyze the concomitant spontaneous breaking of translation and conformal symmetries by introducing in a CFT a complex scalar operator that acquires a spatially dependent expectation value.

Spontaneous breaking of the BRST symmetry in the ABJM theory

Physics Letters B, 2014
In this paper, we will analyze the ghost condensation in the ABJM theory. We will perform our analysis in N=1 superspace. We show that in the Delbourgo–Jarvis–Baulieu–Thierry–Mieg gauge the spontaneous breaking of BRST symmetry can occur in the ABJM ...

Can spontaneous symmetry breaking occur in potential with one minima? [PDF]

arXiv, 2000
Spontaneous symmetry breaking occurs when the symmetry that a physical system possesses, is not preserved for the ground state of the system. Although the procedure of symmetry breaking is quite clear from the mathematical point of view, the physical interpretation of the phenomenon is worth to be better understood. In this note we present a simple and

Spontaneous symmetry breaking in polar fluids [PDF]

Nature Communications
Spontaneous symmetry breaking and emergent polar order are each of fundamental importance to a range of scientific disciplines, as well as generating rich phase behaviour in liquid crystals (LCs). Here, we show the union of these phenomena to lead to two

Spontaneous Symmetry Breaking of q-Gauge Field Theory [PDF]

arXiv, 1999
In non-Abelian field theories with q-symmetry groups the massive particles have a non-local interpretation with a stringlike spectrum. It is shown that a massless vector similarly acquires a tower of masses by spontaneous symmetry breaking.
