Entanglement-enabled symmetry-breaking orders [PDF]
SciPost Physics Core, 2022 A spontaneous symmetry-breaking order is conventionally described by a tensor-product wavefunction of some few-body clusters; some standard examples include the simplest ferromagnets and valence bond solids. We discuss a type of symmetry-breaking orders,

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.

``Induced'' Super-Symmetry Breaking with a Vanishing Vacuum Energy [PDF]
Nucl.Phys. B505 (1997) 123-138, 1996 A new mechanism for symmetry breaking is proposed which naturally avoids the constraints following from the usual theorems of symmetry breaking. In the context of super-symmetry, for example, the breaking may be consistent with a vanishing vacuum energy.

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

Symmetries of Symmetry Breaking Constraints [PDF]
arXiv, 2010 Symmetry is an important feature of many constraint programs. We show that any problem symmetry acting on a set of symmetry breaking constraints can be used to break symmetry. Different symmetries pick out different solutions in each symmetry class. This simple but powerful idea can be used in a number of different ways.

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 ...

On the symmetry breaking phenomenon [PDF]
International Journal of Geometric Methods in Modern Physics, 2006 We investigate the problem of symmetry breaking in the framework of dynamical systems with symmetry on a smooth manifold. Two cases will be analyzed: general and Hamiltonian dynamical systems.

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 ...

Symmetry Breaking at enhanced Symmetry Points [PDF]
Nuclear Physics B, 1995 The influence of world-sheet boundary condensates on the toroidal compactification of bosonic string theories is considered. At the special points in the moduli space at which the closed-string theory possesses an enhanced unbroken $G\times G$ symmetry ...
