2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

open access: yesAdvanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

$SO/Sp$ Chern-Simons Gauge Theories At Large $N$, $SO/Sp$ Penner Models And The Gauge Group Volumes

open access: yes, 2012
We construct a deformed $SO/Sp$ Penner generating function responsible for the close connection between $SO/Sp$ Chern-Simons gauge theories at large $N$ and the $SO/Sp$ Penner models.

On Weil homomorphism in locally free sheaves over structured spaces

open access: yesDemonstratio Mathematica, 2017
Inspired by the work of Heller and Sasin [1], we construct in this paper Weil homomorphism in a locally free sheaf W of ϕ-fields [2] over a structured space.

Symmetric space λ-model exchange algebra from 4d holomorphic Chern-Simons theory

open access: yesJournal of High Energy Physics, 2021
We derive, within the Hamiltonian formalism, the classical exchange algebra of a lambda deformed string sigma model in a symmetric space directly from a 4d holomorphic Chern-Simons theory.

Cosmological time and the constants of nature

open access: yesPhysics Letters B, 2021
We propose that cosmological time is effectively the conjugate of the constants of nature. Different definitions of time arise, with the most relevant related to the constant controlling the dynamics in each epoch. The Hamiltonian constraint then becomes

Explicit Connection Between Conformal Field Theory and 2+1 Chern–Simons Theory [PDF]

open access: yesModern Physics Letters A, 1997
We give explicit field theoretical representations for the observables of (2+1)-dimensional Chern–Simons theory in terms of gauge-invariant composites of 2-D WZW fields. To test our identification we compute some basic Wilson loop correlators and re-obtain the known results.

Layer‐Dependent Antiferromagnetic Chern and Axion Insulating States in UOTe

open access: yesAdvanced Science, EarlyView.
Layer‐dependent topological phases are identified in the van der Waals antiferromagnet UOTe. Ab initio calculations reveal bilayer UOTe as a rare example of high‐temperature antiferromagnetic Chern insulator with quantized Hall conductivity and near‐zero net magnetization, while odd‐layer films exhibit axion‐insulator‐like behavior with quantized spin ...

Fermi gas formalism for D-type quiver Chern-Simons theory with non-uniform ranks

open access: yesJournal of High Energy Physics
We construct the Fermi gas formalism for the partition function of supersymmetric Chern-Simons theories with affine D-type quiver diagrams with non-uniform ranks of the gauge groups and Fayet-Illiopoulos parameters by two different approaches: the open ...

Realization of a Bilayer Elastic Topological Insulator

open access: yesAdvanced Science, EarlyView.
Bilayer elastic wave topological insulators are experimentally realized, introducing the layer degree of freedom to access four topological phases. This enables diverse domain walls and transmission behaviors, including interlayer conversion and beam splitting.

A symmetric Finsler space with Chern connection

open access: yes, 2007
We define a symmetry for a Finsler space with Chern connection and investigate its implementation and properties and find a relation between them and flag curvature.
