Directional Flow of Confined Polaritons in CrSBr
Advanced Materials, EarlyView.CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

Charged and Electromagnetic Fields from Relativistic Quantum Geometry
Universe, 2016 In the recently introduced Relativistic Quantum Geometry (RQG) formalism, the possibility was explored that the variation of the tensor metric can be done in a Weylian integrable manifold using a geometric displacement, from a Riemannian to a Weylian ...

Explicit form of the Mann-Marolf surface term in (3+1) dimensions
, 2009 The Mann-Marolf surface term is a specific candidate for the "reference background term" that is to be subtracted from the Gibbons-Hawking surface term in order make the total gravitational action of asymptotically flat spacetimes finite.

Extension of Moore–Penrose inverse of tensor via Einstein product [PDF]
Linear and multilinear algebra, 2018 The notion of the Moore–Penrose inverse of an even-order tensor and the two-term reverse-order law for the Moore–Penrose inverse of even-order tensors via the Einstein product were introduced, very recently.

Kaehlerian Manifolds on Einstein-Recurrent curvature tensor
Journal of Mountain Research, 2022 Bochner (1949) obtained some results on curvature and betti numbers. Hasegawa (1974) studied on H projective recurrent Kaehlerian manifolds and Bochner recurrent Kaehlerian manifolds. Also, Negi (2016) obtained Some Recurrence Properties in Kaehlerian, Einstein Kaehlerian and Tachibana Spaces. After that, Negi et. al.

Advanced Materials, EarlyView.Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

A New Unified Theory of Electromagnetic and Gravitational Interactions
, 2016 In this paper we present a new unified theory of electromagnetic and gravitational interactions. By considering a four-dimensional spacetime as a hypersurface embedded in a five-dimensional bulk spacetime, we derive the complete set of field equations in

Black hole thermodynamics in ( $$2+1$$ 2 + 1 )-dimensional scalar–tensor-Born–Infeld theory
European Physical Journal C: Particles and Fields, 2022 The action of scalar–tensor (ST) gravity theory can be written in both of the Jordan and Einstein frames, which are related via conformal transformations.
