Spontaneous supersymmetry breaking in inhomogeneous supersymmetric field theories and BPS vacua
Journal of High Energy Physics, 2023 We study spontaneous supersymmetry breaking in inhomogeneous extensions of N $$ \mathcal{N} $$ = 1 supersymmetric field theory models in 4-dimensions.

Mutual information and spontaneous symmetry breaking [PDF]
Physical Review A, 2016 We show that the metastable, symmetry-breaking ground states of quantum many-body Hamiltonians have vanishing quantum mutual information between macroscopically separated regions, and are thus the most classical ones among all possible quantum ground states.

Spontaneous Symmetry Breaking in 5D Conformally Invariant Gravity
Advances in High Energy Physics, 2016 We explore the possibility of the spontaneous symmetry breaking in 5D conformally invariant gravity, whose action consists of a scalar field nonminimally coupled to the curvature with its potential. Performing dimensional reduction via ADM decomposition,

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 .

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 breaking of spatial and spin symmetry in spinor condensates [PDF]
, 2010 Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric amplifier of spin modes, resulting in a twofold spontaneous breaking of ...

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

Inflation as a spontaneous symmetry breaking of Weyl symmetry [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 In this paper we study a novel realization of inflation, based on Weyl invariant gravity with torsion. We show that requiring the classical action for the scalar field to be Weyl invariant introduces a dilaton which induces a non trivial modification of the field space geometry of the scalar sector, which allows for inflationary phase that begins at ...
