Projective symmetry group classification of chiral spin liquids [PDF]
, 2015 We present a general review of the projective symmetry group classification of fermionic quantum spin liquids for lattice models of spin $S=1/2$. We then introduce a systematic generalization of the approach for symmetric $\mathbb{Z}_2$ quantum spin ...

A double chain of coupled circuits in analogy with mechanical lattices
International Journal of Mathematics and Mathematical Sciences, 1991 A unitary transformation obtained from group theoretical considerations is applied to the problem of finding the resonant frequencies of a system of coupled LC-circuits.

Topological axion electrodynamics and 4-group symmetry
Physics Letters B, 2021 We study higher-form symmetries and a higher group in the low energy limit of a (3+1)-dimensional axion electrodynamics with a massive axion and a massive photon.

Symmetry protected topological orders and the group cohomology of their symmetry group [PDF]
, 2011 Symmetry protected topological (SPT) phases are gapped short-range-entangled quantum phases with a symmetry G. They can all be smoothly connected to the same trivial product state if we break the symmetry.

The Quaternion Group as a Symmetry Group [PDF]
, 2014 We briefly review the distinction between abstract groups and symmetry groups of objects, and discuss the question of which groups have appeared as the symmetry groups of physical objects.

Gauging Lie group symmetry in (2+1)d topological phases
SciPost Physics, 2023 We present a general algebraic framework for gauging a 0-form compact, connected Lie group symmetry in (2+1)d topological phases. Starting from a symmetry fractionalization pattern of the Lie group $G$, we first extend $G$ to a larger symmetry group ...

Hypernuclear matter in a complete SU(3) symmetry group [PDF]
, 2013 Using the well known quantum hadrodynamics (QHD), we study the effects of meson-hyperon coupling constants on the onset of hyperons in dense nuclear matter.

Clifford Group and Unitary Designs under Symmetry
PRX Quantum, 2023 We have generalized the well-known statement that the Clifford group is a unitary 3-design into symmetric cases by extending the notion of unitary design.

Orbit Entropy and Symmetry Index Revisited
Mathematics, 2021 The size of the orbits or similar vertices of a network provides important information regarding each individual component of the network. In this paper, we investigate the entropy or information content and the symmetry index for several classes of ...

Symmetries, Group Actions, and Entanglement [PDF]
Open Systems & Information Dynamics, 2006 We address several problems concerning the geometry of the space of Hermitian operators on a finite-dimensional Hilbert space, in particular the geometry of the space of density states and canonical group actions on it. For quantum composite systems we discuss and give examples of entanglement measures.
