DFT‐Based Insights Into Elastic, Thermophysical, Electronic, and Optical Properties of Topological Insulators XTe5 (X = Zr, Hf)

Advanced Physics Research, EarlyView.
In this work, we present the first in‐depth investigation of elasto‐mechanical, thermophysical, and optical properties of these compounds. In particular, we analyzed the directional dependence of the elastic properties, explored the optical response for different photon polarization directions, and examined potential industrial applications of these ...

The Hodge Chern character of holomorphic connections as a map of simplicial presheaves

Algebraic & Geometric Topology, 2022
We define a map of simplicial presheaves, the Chern character, that assigns to every sequence of composable non connection preserving isomorphisms of vector bundles with holomorphic connections an appropriate sequence of holomorphic forms. We apply this Chern character map to the Cech nerve of a good cover of a complex manifold and assemble the data by

Equivariant toric geometry and Euler–Maclaurin formulae

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Higher dimensional quantum Hall effect as A-class topological insulator

Nuclear Physics B, 2014
We perform a detail study of higher dimensional quantum Hall effects and A-class topological insulators with emphasis on their relations to non-commutative geometry.

Wilson loop algebras and quantum K-theory for Grassmannians

Journal of High Energy Physics, 2020
We study the algebra of Wilson line operators in three-dimensional N $$ \mathcal{N} $$ = 2 supersymmetric U(M ) gauge theories with a Higgs phase related to a complex Grassmannian Gr(M, N ), and its connection to K-theoretic Gromov-Witten invariants for ...

The holographic c-theorem and infinite-dimensional Lie algebras

Journal of High Energy Physics, 2022
We discuss a non-dynamical theory of gravity in three dimensions which is based on an infinite-dimensional Lie algebra that is closely related to an infinite-dimensional extended AdS algebra.

Investigation of Social Media Metrics With Respect to Demand Modeling for Promotional Products

Journal of Forecasting, EarlyView.
ABSTRACT Social media (SM) has revolutionized the way companies connect with customers, enabling more personalized marketing strategies and enhancing engagement. With platforms like Facebook offering detailed user data, businesses can create more targeted advertising campaigns. This paper proposes an approach to categorizing SM variables based on their

Bulk‐Edge Correspondence and Multiplexing Topological Routings in Gyromagnetic Photonic Weyl Metamaterials

Laser &Photonics Reviews, EarlyView.
In this work, various topological phases and the bulk‐edge correspondence are studied and established in gyromagnetic photonic Weyl metamaterials. Based on rigorous theoretical analysis, the comprehensive depictions of the multiple topological phase diagrams and multi‐type bulk‐edge correspondences are further mapped out.

Tunable Topological Directional Supercoupler and Applications in THz On‐Chip Communication

Laser &Photonics Reviews, EarlyView.
A topological directional supercoupler is demonstrated, enabling dual‐channel 50 Gbps on‐chip terahertz communication with phototunable power splitting ratios. The achieved sub‐wavelength scale coupling area, sharp waveguide bends, and momentum‐conserved coupling process allow for ultra‐compact and efficient terahertz topological photonic integrated ...
