Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2

open access: yesAdvanced Quantum Technologies, EarlyView.
Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

Chern-Simons theory, decomposition, and the A model

open access: yesJournal of High Energy Physics
In this paper, we discuss how gauging one-form symmetries in Chern-Simons theories is implemented in an A-twisted topological open string theory. For example, the contribution from a fixed H/Z bundle on a three-manifold M, arising in a BZ gauging of H ...

A first-class approach of higher derivative Maxwell–Chern–Simons–Proca model [PDF]

open access: yes, 2014
The equivalence between a higher derivative extension of Maxwell–Chern–Simons–Proca model and some gauge invariant theories from the point of view of the Hamiltonian path integral quantization in the framework of the gauge-unfixing approach is ...

MnBr2${\rm MnBr}_2$ on the Graphene on Ir(110) Substrate: Growth, Structure, and Super‐Moiré

open access: yesSmall, EarlyView.
The study realizes single‐layer MnBr2${\rm MnBr}_2$ via molecular beam epitaxy on graphene on Ir(110), unveiling a unique super‐moiré (“moiré of moirés”) formed by lattices of different symmetries. Remarkably, this super‐moiré is driven by a virtual interaction between non‐contacting layers.

Investigation of English Language Learners’ Attitudes Toward Global Englishes and Global Englishes Language Teaching in Relation to Their Academic Interests and Experiences With English as a Global Lingua Franca

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study investigates Japanese university students’ attitudes toward Global Englishes (GE) and Global Englishes Language Teaching (GELT), focusing on how these attitudes are shaped by students’ academic interests and experiences using English as a lingua franca (ELF), both abroad and in domestic EFL contexts.

Chern-Simons theory from M5-branes and calibrated M2-branes

open access: yesJournal of High Energy Physics, 2019
We study a sector of the 5d maximally supersymmetric Yang-Mills theory on S 5 consisting of 1/8-BPS Wilson loop operators contained within a great S 3 inside S 5.

Toward Kitaev's sixteenfold way in a honeycomb lattice model

open access: yesPhysical Review Research, 2020
Kitaev's sixteenfold way is a classification of exotic topological orders in which Z_{2} gauge theory is coupled to Majorana fermions of Chern number C. The 16 distinct topological orders within this class, depending on Cmod16, possess a rich variety of ...

Information systems and digitization of traditional knowledge: Trends in cultural heritage and memory institutions and the WIPO Genetic Resources Treaty*

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract Understanding the role of information communication technologies (ICTs) in development, especially in relation to marginalized populations, has been the focus of many related disciplinary categories within the broader ecosystem of information sciences.

On M-theory fourfold vacua with higher curvature terms

open access: yesPhysics Letters B, 2015
We study solutions to the eleven-dimensional supergravity action, including terms quartic and cubic in the Riemann curvature, that admit an eight-dimensional compact space.

Equivariant toric geometry and Euler–Maclaurin formulae

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.
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.
