A model of persistent breaking of continuous symmetry
SciPost Physics, 2022 We consider a UV-complete field-theoretic model in general dimensions, including $d=2+1$, that exhibits spontaneous breaking of continuous symmetry, persisting to arbitrarily large temperatures.

Spontaneous Symmetry Breaking and Goldstone Theorem [PDF]
, 2023 We discuss the concept of spontaneous symmetry breaking and illustrate it with a general example. We consider Wigner-Weyl and Nambu-Goldstone realisations of symmetry in the quantum theory. Next, we state Goldstone’s theorem and sketch its proof.

, 2008 One of the most powerful ideas of modern theoretical physics is the mechanism of spontaneous symmetry breaking. It is at the basis of most of the recent achievements in the description of phase transitions in Statistical Mechanics as well as of collective phenomena in solid state physics.

Bottom quark and tau lepton masses in a toy $$\textrm{SU}(6)$$ SU ( 6 ) model
European Physical Journal C: Particles and Fields, 2023 We study a toy $$\textrm{SU}(6)$$ SU ( 6 ) model with the symmetry breaking pattern of the extended 331 symmetry of $$\textrm{SU}(3)_c \otimes \textrm{SU}(3)_W \otimes \textrm{U}(1)_X$$ SU ( 3 ) c ⊗ SU ( 3 ) W ⊗ U ( 1 ) X .

Spontaneous breaking of non-relativistic scale symmetry
Journal of High Energy Physics, 2017 We analyze the mechanism of spontaneous symmetry breaking of scale invariance in Galilean invariant field theories. We show that the existence of a dynamic gapless dilaton mode depends on whether the U(1) particle number or the Galilean boost symmetry ...

Non-Hermitian non-Abelian topological insulators with PT symmetry
Physical Review Research, 2021 We study a non-Hermitian non-Abelian topological insulator preserving PT symmetry, where the non-Hermitian term represents nonreciprocal hoppings. As it increases, a spontaneous PT symmetry breaking transition occurs in the perfect-flat band model from a

MethodsX, 2023 Homochirality, the phenomenon by which one of two virtually identical (non-superimposable mirror images) compounds is favored over the other in the chemistry of life, has been regarded as a requisite for the emergence of all living things on earth ...

Spontaneous symmetry breaking of coupled Fabry–Pérot nanocavities
Communications PhysicsRing cavities are quickly emerging as preferential platforms to investigate spontaneous symmetry breaking. However, research on handedness polarisation splitting within Kerr-coupled cavities is yet at a preliminary stage.
