Discrete Scale Relativity And SX Phoenicis Variable Stars
, 2009 Discrete Scale Relativity proposes a new symmetry principle called discrete cosmological self-similarity which relates each class of systems and phenomena on a given Scale of nature's discrete cosmological hierarchy to the equivalent class of analogue ...

Advanced Engineering Materials, EarlyView.This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.

Radiative mixing of the one Higgs boson and emergent self-interacting dark matter
Physics Letters B, 2016 In all scalar extensions of the standard model of particle interactions, the one Higgs boson responsible for electroweak symmetry breaking always mixes with other neutral scalars at tree level unless a symmetry prevents it. An unexplored important option

Goldstone bosons in different PT-regimes of non-Hermitian scalar quantum field theories
Nuclear Physics B, 2020 We study the interplay between spontaneously breaking global continuous and discrete antilinear symmetries in a newly proposed general class of non-Hermitian quantum field theories containing a mixture of complex and real scalar fields.

The other variants of mixed μ-τ symmetry
Nuclear Physics B, 2023 Two new neutrino mass matrix textures exhibiting the mixed μ-τ symmetry are proposed. The mass matrices hint for a promising neutrino mixing schemes and find their connections with Δ(27) and A4 discrete symmetry groups respectively.

Non-Abelian Discrete Groups from the Breaking of Continuous Flavor Symmetries
, 2009 We discuss the possibility of obtaining a non-abelian discrete flavor symmetry from an underlying continuous, possibly gauged, flavor symmetry SU(2) or SU(3) through spontaneous symmetry breaking.

Fermion Systems in Discrete Space-Time - Outer Symmetries and Spontaneous Symmetry Breaking [PDF]
, 2007 A systematic procedure is developed for constructing fermion systems in discrete space-time which have a given outer symmetry. The construction is illustrated by simple examples. For the symmetric group, we derive constraints for the number of particles.

Advanced Engineering Materials, EarlyView.Steel samples are investigated using complementary simulations and measurements. Transmission electron microscopy in bright‐field mode, combined with energy‐dispersive X‐ray spectroscopy maps for titanium and niobium, reveals distinct particle populations. Simulations reproduce these in size and composition.

Journal of High Energy Physics, 2018 This paper tests a conjecture on discrete non-Abelian gauging of 3d N=4 $$ \mathcal{N}=4 $$ supersymmetric quiver gauge theories. Given a parent quiver with a bouquet of n nodes of rank 1, invariant under a discrete S n global symmetry, one can construct
