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 ...

Temporal Arrows in Space-Time [PDF]
, 2013 The prevailing current of thought in both physics and philosophy is that relativistic space-time provides no means for the objective measurement of the passage of time. Kurt Gödel, for instance, denied the possibility of an objective lapse of time, both

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.

Breaking conditional symmetry in automated constraint modelling with CONJURE [PDF]
, 2014 This work was supported by UK EPSRC EP/K015745/1. Jefferson is supported by a Royal Society University Research Fellowship.Many constraint problems contain symmetry, which can lead to redundant search.

Generalized unitary evolution for symplectic scalar fermions
Journal of High Energy PhysicsThe theory of symplectic scalar fermion of LeClair and Neubert is studied. The theory evades the conventional spin-statistics theorem because its Hamiltonian is pseudo Hermitian. The definition of pseudo Hermiticity is examined in the interacting and the

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

, 2007 While empirical symmetries relate situations, theoretical symmetries relate models of a theory we use to represent them. An empirical symmetry is perfect if and only if any two situations it relates share all intrinsic properties. Sometimes one can use a

Carrollian and Galilean conformal higher-spin algebras in any dimensions
Journal of High Energy Physics, 2022 We present higher-spin algebras containing a Poincaré subalgebra and with the same set of generators as the Lie algebras that are relevant to Vasiliev’s equations in any space-time dimension D ≥ 3. Given these properties, they can be considered either as
