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.

Division algebraic symmetry breaking
Physics Letters B, 2022 Reframing certain well-known particle models in terms of normed division algebras leads to two new results for BSM physics.(1) We identify a sequence of complex structures which induces a cascade of breaking symmetries: Spin(10) ↦ Pati-Salam ↦ Left-Right

Selection rules for breaking selection rules
New Journal of Physics, 2021 Floquet systems often exhibit dynamical symmetries (DS) that govern the time-dependent dynamics and result in selection rules. When a DS is broken, selection rule deviations are expected.

Magnetoexcitons Break Antiunitary Symmetries [PDF]
Physical Review Letters, 2017 We show analytically and numerically that the application of an external magnetic field to highly excited Rydberg excitons breaks all antiunitary symmetries in the system. Only by considering the complete valence band structure of a direct band gap cubic semiconductor, the Hamiltonian of excitons leads to the statistics of a Gaussian unitary ensemble ...

Spontaneous Scale Symmetry Breaking in 2+1-Dimensional QED at Both Zero and Finite Temperature [PDF]
, 2000 A complete analysis of dynamical scale symmetry breaking in 2+1-dimensional QED at both zero and finite temperature is presented by looking at solutions to the Schwinger-Dyson equation.

Influence of symmetry breaking on the fluctuation properties of spectra [PDF]
, 2001 We study the effect of gradual symmetry breaking in a non-integrable system on the level fluctuation statistics. We consider the case when the symmetry is represented by a quantum number that takes one of two possible values, so that the unperturbed ...
