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.

Symmetry-Breaking Motility [PDF]

Physical Review Letters, 2004
Locomotion of bacteria by actin polymerization, and in vitro motion of spherical beads coated with a protein catalyzing polymerization, are examples of active motility.

Realization of a spontaneous gauge and supersymmetry breaking vacuum [PDF]

Journal of High Energy Physics, 2017
It is one of the major issues to realize a vacuum which breaks supersymmetry (SUSY) and R-symmetry, in a supersymmetric model. We study the model, where the same sector breaks the gauge symmetry and SUSY. In general, the SUSY breaking model without gauge

R Symmetry Breaking Versus Supersymmetry Breaking [PDF]

Nuclear 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

European 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 ...

Fast self-healing in a layered molecular crystal mediated by stress-induced symmetry breaking [PDF]

Nature Communications
In recent years, symmetry-breaking has emerged as a powerful tool for significantly altering various physical properties in 2D layered materials. However, the breaking of symmetry by means of mechanical stress in organic crystals remains elusive.

Spontaneous Symmetry Breaking and Chiral Symmetry [PDF]

AIP 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]

Nature 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]

Communications 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]

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.
