Unmixing Symmetries [PDF]

open access: yesPhysical Review Letters, 2020
The low-lying spectra of atomic nuclei display diverse behaviors, for example rotational bands, which can be described phenomenologically by simple symmetry groups such as spatial SU(3). This leads to the idea of dynamical symmetry, where the Hamiltonian commutes with the Casimir operator(s) of a group, and is block-diagonal in subspaces defined by the

A computational group theoretic symmetry reduction package for the SPIN model checker [PDF]

open access: yes, 2006
Symmetry reduced model checking is hindered by two problems: how to identify state space symmetry when systems are not fully symmetric, and how to determine equivalence of states during search.

New Exact Solutions for a Generalized Double Sinh-Gordon Equation

open access: yesAbstract and Applied Analysis, 2013
We study a generalized double sinh-Gordon equation, which has applications in various fields, such as fluid dynamics, integrable quantum field theory, and kink dynamics. We employ the Exp-function method to obtain new exact solutions for this generalized

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Vetoing all the Higgs imposters in $$H\rightarrow \ell ^-\ell ^+ Z$$ H → ℓ - ℓ + Z

open access: yesEuropean Physical Journal C: Particles and Fields
We develop an effective and methodical algorithm for the construction of general covariant four-point $$H\ell \ell Z$$ H ℓ ℓ Z vertices, accommodating leptons $$\ell =e, \mu $$ ℓ = e , μ , and designed to handle a boson H of any integer spin, not merely ...

Symmetry TFT for subsystem symmetry

open access: yesJournal of High Energy Physics
A bstract We generalize the idea of symmetry topological field theory (SymTFT) for subsystem symmetry. We propose the 2-foliated BF theory with level N in (3 + 1)d as subsystem SymTFT for subsystem

Restricted Weyl symmetry and spontaneous symmetry breakdown of conformal symmetry [PDF]

open access: yesModern Physics Letters A, 2021
In this paper, we elucidate the relation between the restricted Weyl symmetry and spontaneous symmetry breakdown of conformal symmetry. Using a scalar–tensor gravity, we show that the restricted Weyl symmetry leads to spontaneous symmetry breakdown of a global scale symmetry when the vacuum expectation value of a scalar field takes a nonzero value. It

Mathematics via Symmetry [PDF]

open access: yes, 2013
We state the defining characteristic of mathematics as a type of symmetry where one can change the connotation of a mathematical statement in a certain way when the statement's truth value remains the same.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Conservation Laws and Traveling Wave Solutions of a Generalized Nonlinear ZK-BBM Equation

open access: yesAbstract and Applied Analysis, 2014
We study a generalized two-dimensional nonlinear Zakharov-Kuznetsov-Benjamin-Bona-Mahony (ZK-BBM) equation, which is in fact Benjamin-Bona-Mahony equation formulated in the ZK sense.
