Covert symmetry breaking [PDF]
Journal 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.

Halogen bond-modulated solid-state reordering and symmetry breaking of azahelicenes [PDF]
Nature CommunicationsSpontaneous 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]
Communications ChemistrySymmetry 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]
Nuclear 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
Proceedings (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.

Electronic 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
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 .

Symmetry-Breaking Motility [PDF]
Physical Review Letters, 2005 Locomotion of bacteria by actin polymerization, and in vitro motion of spherical beads coated with a protein catalyzing polymerization, are examples of active motility. Starting from a simple model of forces locally normal to the surface of a bead, we construct a phenomenological equation for its motion.

Effects of symmetry-breaking on electromagnetic backscattering
Scientific Reports, 2021 Systems with a discrete rotational symmetry $$2\pi /n$$ 2 π / n where $$n\ge 3$$ n ≥ 3 that also have electromagnetic duality symmetry exhibit zero backscattering.

Semaphorin Breaks Symmetry [PDF]
Neuron, 2011 Axon-dendrite polarity is likely instructed by extrinsic cues in the developing nervous system, though the mechanisms governing this process remain to be fully elucidated. In this issue of Neuron, Shelly et al. show that the axon guidance cue Semaphorin 3A can promote dendrite growth by inhibiting axon specification.
