Discrete Lorentz symmetry and discrete time translational symmetry
New Journal of Physics, 2018 The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are the manifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.

Modular Hamiltonian for de Sitter diamonds
Journal of High Energy Physics, 2023 We determine the Tomita-Takesaki modular data for CFTs in double cone and light cone regions in conformally flat spacetimes. This includes in particular the modular Hamiltonian for diamonds in the de Sitter spacetime.

Symmetries of String Effective Action and Space-Time Geometry [PDF]
, 1992 Two dimensional charged black hole solution is obtained by implementing an $O(2,2)$ transformation on the three dimensional black string solution. Two different monopole backgrounds in five dimensions are related through an $O(2,2)$ transformation.

Asymptotic symmetries of Yang-Mills fields in Hamiltonian formulation
Journal of High Energy Physics, 2020 We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism to the case of gravity and ...

COLORED SYMMETRIES IN SPACE–TIME
Computers & Mathematics with Applications, 1986 AbstractThe paper displays a single objective: to show the emergence of symmetries as a universal, archetypal, self-organizing phenomenon which originates in an infinite number of forms all having the same trihedral innate structure. These forms have been generated by the use of a single-type, right-handed element containing three spatial dimensions ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Irreducible representations of the Poincaré group with reflections and two-fold Wigner degeneracy
Journal of High Energy PhysicsNot all complete set of spinors can be used as expansion coefficients of a quantum field. In fact, Steven Weinberg established the uniqueness of Dirac spinors for this purpose provided: (a) one paid due attention to the multiplicative phases for each of ...

Hamiltonian structure and asymptotic symmetries of the Einstein-Maxwell system at spatial infinity
Journal of High Energy Physics, 2018 We present a new set of asymptotic conditions for gravity at spatial infinity that includes gravitational magnetic-type solutions, allows for a non-trivial Hamiltonian action of the complete BM S 4 algebra, and leads to a non-divergent behaviour of the ...
