On the relationship between gauge dependence and IR divergences in the ℏ-expansion of the effective potential

Journal of High Energy Physics, 2019
Perturbative calculations of the effective potential evaluated at a broken minimum, V min, are plagued by difficulties. It is hard to get a finite and gauge invariant result for V min.

Anomaly inflow, accidental symmetry, and spontaneous symmetry breaking

Journal of High Energy Physics, 2020
We consider the 6d (1,0) SCFT on a stack of N M5-branes probing a ℂ2/ℤ2 singularity. In particular, we study its compactifications to four dimensions on a smooth genus-g Riemann surface with non-trivial flavor flux, yielding a family of 4d CFTs.

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 ...

Patterns of Spontaneous Chiral Symmetry Breaking in Vectorlike Gauge Theories [PDF]

, 2001
It has been conjectured that spontaneous chiral symmetry breaking in strongly coupled vectorlike gauge theories falls into only three different classes, depending on the gauge group and the representations carried by the fermions.

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.

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 gravity [PDF]

, 2011
Gravity is usually considered to be irrelevant as far as the physics of elementary particles is concerned and, in particular, in the context of the spontaneous symmetry breaking (SSB) mechanism. We describe a version of the SSB mechanism in which gravity

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 .

Time crystal behavior of excited eigenstates

, 2017
In analogy to spontaneous breaking of continuous space translation symmetry in the process of space crystal formation, it was proposed that spontaneous breaking of continuous time translation symmetry could lead to time crystal formation. In other words,
