Covert symmetry breaking [PDF]

open access: yesJournal of High Energy Physics, 2020
Reduction from a higher-dimensional to a lower-dimensional field theory can display special features when the zero-level ground state has nontrivial dependence on the reduction coordinates.

R Symmetry Breaking Versus Supersymmetry Breaking [PDF]

open access: yesNuclear Physics B, 1993
We point out a connection between R symmetry and \susy\ breaking. We show that the existence of an R symmetry is a necessary condition for \susy\ breaking and a spontaneously broken R symmetry is a sufficient condition provided two conditions are ...

Probing the two-scale-factor universality hypothesis by exact rotation symmetry-breaking mechanism

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We probe the two-scale-factor universality hypothesis by evaluating, firstly explicitly and analytically at the one-loop order, the loop quantum corrections to the amplitude ratios for O(N) $$\lambda \phi ^{4}$$ λ ϕ 4 scalar field theories with rotation ...

Spontaneous Symmetry Breaking and Chiral Symmetry [PDF]

open access: yesAIP Conference Proceedings, 2000
In this introductory lecture, some basic features of the spontaneous symmetry breaking are discussed. More specifically, $\sigma $-model, non-linear realization, and some examples of spontaneous symmetry breaking in the non-relativistic system are ...

Halogen bond-modulated solid-state reordering and symmetry breaking of azahelicenes [PDF]

open access: yesNature Communications
Spontaneous symmetry breaking predominately occurs during the aggregation of discrete molecules in solution. Herein, we report a unique solid-state symmetry breaking process of dynamically chiral aza[4]helicenes that emerged in vacuum-driven ...

Ultrafast probing of isotope-induced explicit symmetry breaking in ethylene [PDF]

open access: yesCommunications Chemistry
Symmetry governs nature’s laws, yet many of the natural phenomena occur due to the breakdown of symmetry. Here, we show how isotope-induced inversion symmetry breaking influences ultrafast photoisomerization processes in ethylene.

Symmetries and symmetry breaking [PDF]

open access: yesNuclear Physics A, 2001
In understanding the world of matter, the introduction of symmetry principles following experimentation or using the predictive power of symmetry principles to guide experimentation is most profound. The conservation of energy, linear momentum, angular momentum, charge, and CPT involve fundamental symmetries.

Symmetry and symmetry breaking in science and arts

open access: yesProceedings (European Academy of Sciences and Arts), 2022
In this review article, symmetry and symmetry breaking are considered as complementary principles in science and arts. It starts with symmetry and symmetry breaking in early world views of nature and art.

Breaking Symmetries [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
A well-known result by Palamidessi tells us that πmix(the π-calculus with mixed choice) is more expressive than πsep(its subset with only separate choice). The proof of this result analyses their different expressive power concerning leader election in symmetric networks.

Bottom quark and tau lepton masses in a toy $$\textrm{SU}(6)$$ SU ( 6 ) model

open access: yesEuropean 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 .
