Algebraic higher symmetry and categorical symmetry -- a holographic and entanglement view of symmetry [PDF]
, 2020 We introduce the notion of algebraic higher symmetry, which generalizes higher symmetry and is beyond higher group. We show that an algebraic higher symmetry in a bosonic system in $n$-dimensional space is characterized and classified by a local fusion ...

Noninvertible Chiral Symmetry and Exponential Hierarchies [PDF]
Physical Review X, 2022 We elucidate the fate of classical symmetries which suffer from abelian Adler-Bell-Jackiw anomalies. Instead of being completely destroyed, these symmetries survive as non-invertible topological global symmetry defects with worldvolume anyon degrees of ...

Holographic symmetry algebras for gauge theory and gravity [PDF]
Journal of High Energy Physics, 2021 All 4D gauge and gravitational theories in asymptotically flat spacetimes contain an infinite number of non-trivial symmetries. They can be succinctly characterized by generalized 2D currents acting on the celestial sphere.

Real Spectra in Non-Hermitian Hamiltonians Having PT Symmetry [PDF]
, 1997 The condition of self-adjointness ensures that the eigenvalues of a Hamiltonian are real and bounded below. Replacing this condition by the weaker condition of $\mathrm{PT}$ symmetry, one obtains new infinite classes of complex Hamiltonians whose spectra

Symmetry and Topology in Non-Hermitian Physics [PDF]
Physical Review X, 2018 We develop a complete theory of symmetry and topology in non-Hermitian physics. We demonstrate that non-Hermiticity ramifies the celebrated Altland-Zirnbauer symmetry classification for insulators and superconductors. In particular, charge conjugation is

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

Symmetry-break in Voronoi tessellations [PDF]
, 2009 We analyse in a common framework the properties of the Voronoi tessellations resulting from regular 2D and 3D crystals and those of tessellations generated by Poisson distributions of points, thus joining on symmetry breaking processes and the approach ...

Conformal symmetry and its breaking in two dimensional Nearly Anti-de-Sitter space [PDF]
, 2016 We study a two dimensional dilaton gravity system, recently examined by Almheiri and Polchinski, which describes near extremal black holes, or more generally, nearly $AdS_2$ spacetimes.

Symmetry Breaking at enhanced Symmetry Points [PDF]
, 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 ...

Crystal time-reversal symmetry breaking and spontaneous Hall effect in collinear antiferromagnets [PDF]
Science Advances, 2019 Identification of a previously overlooked spontaneous Hall effect mechanism creates opportunities in low-dissipation spintronics. Electrons, commonly moving along the applied electric field, acquire in certain magnets a dissipationless transverse ...
