ON THE SYMMETRY BREAKING PHENOMENON [PDF]

open access: yesInternational 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. We give sufficient conditions for symmetry breaking in both cases.

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 ...

Symmetry breaking on density in escaping ants: experiment and alarm pheromone model.

open access: yesPLoS ONE, 2014
The symmetry breaking observed in nature is fascinating. This symmetry breaking is observed in both human crowds and ant colonies. In such cases, when escaping from a closed space with two symmetrically located exits, one exit is used more often than the

Realization of a spontaneous gauge and supersymmetry breaking vacuum

open access: yesJournal 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

Self-organization and symmetry breaking in intestinal organoid development

open access: yesNature, 2019
Intestinal organoids are complex three-dimensional structures that mimic the cell-type composition and tissue organization of the intestine by recapitulating the self-organizing ability of cell populations derived from a single intestinal stem cell ...

Radiative Corrections as the Origin of Spontaneous Symmetry Breaking [PDF]

open access: yes, 1973
We investigate the possibility that radiative corrections may produce spontaneous symmetry breakdown in theories for which the semiclassical (tree) approximation does not indicate such breakdown.

Categorical symmetry and noninvertible anomaly in symmetry-breaking and topological phase transitions [PDF]

open access: yesPhysical Review Research, 2019
For a zero-temperature Landau symmetry breaking transition in $n$-dimensional space that completely breaks a finite symmetry $G$, the critical point at the transition has the symmetry $G$.

Symmetry Breaking of Phospholipids [PDF]

open access: yesSymmetry, 2020
Either stereo reactants or stereo catalysis from achiral or chiral molecules are a prerequisite to obtain pure enantiomeric lipid derivatives. We reviewed a few plausibly organic syntheses of phospholipids under prebiotic conditions with special attention paid to the starting materials as pro-chiral dihydroxyacetone and dihydroxyacetone phosphate (DHAP)

Synchronous symmetry breaking in neurons with different neurite counts. [PDF]

open access: yesPLoS ONE, 2013
As neurons develop, several immature processes (i.e., neurites) grow out of the cell body. Over time, each neuron breaks symmetry when only one of its neurites grows much longer than the rest, becoming an axon. This symmetry breaking is an important step
