The holographic c-theorem and infinite-dimensional Lie algebras

open access: yesJournal 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.

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.

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.

(n-2)-tightness and curvature of submanifolds with boundary

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
The purpose of this note is to establish a connection between the notion of (n−2)-tightness in the sense of N.H. Kuiper and T.F. Banchoff and the total absolute curvature of compact submanifolds-with-boundary of even dimension in Euclidean space.

Integrable lambda models and Chern-Simons theories

open access: yesJournal of High Energy Physics, 2017
In this note we reveal a connection between the phase space of lambda models on S 1 × ℝ $$ {S}^1\times \mathbb{R} $$ and the phase space of double Chern-Simons theories on D × ℝ $$ D\times \mathbb{R} $$ and explain in the process the origin of the non ...

On the Non Metrizability of Berwald Finsler Spacetimes

open access: yesUniverse, 2020
We investigate whether Szabo’s metrizability theorem can be extended to Finsler spaces of indefinite signature. For smooth, positive definite Finsler metrics, this important theorem states that, if the metric is of Berwald type (i.e., its Chern–Rund ...

Adiabatic continuity between Hofstadter and Chern insulator states

open access: yes, 2012
We show that the topologically nontrivial bands of Chern insulators are adiabatic cousins of the Landau bands of Hofstadter lattices. We demonstrate adiabatic connection also between several familiar fractional quantum Hall states on Hofstadter lattices ...
