General construction of flat bands with and without band crossings based on wave function singularity
Yoonseok Hwang, Jun-Won Rhim, Bohm-Jung Yang
In this work, we develop a systematic method of constructing flat-band models with and without band crossings. Our construction scheme utilizes the symmetry and spatial shape of a…
Polarization and localization of single-photon emitters in hexagonal boron nitride wrinkles
Donggyu Yim, Mihyang Yu, Gichang Noh +2
Color centers in 2-dimensional hexagonal boron nitride (h-BN) have recently emerged as stable and bright single-photon emitters (SPEs) operating at room temperature. In this study,…
Antiferromagnetic ordering in van der Waals two-dimensional magnetic material MnPS3 probed by Raman spectroscopy
Kangwon Kim, Soo Yeon Lim, Jungcheol Kim +8
Magnetic ordering in the two-dimensional limit has been one of the most important issues in condensed matter physics for the past several decades. The recent discovery of new magne…
Theory of optically induced Förster Coupling in van der Waals coupled Heterostuctures
Malte Selig, Ermin Malic, Kwang Jun Ahn +2
We investigate the impact of optically induced Förster coupling in van der Waals heterostructures consisting of graphene and a monolayer transition metal dichalcogenide (TMD). In p…
Designing defect-based qubit candidates in wide-gap binary semiconductors for solid-state quantum technologies
Hosung Seo, He Ma, Marco Govoni +1
The development of novel quantum bits is key to extend the scope of solid-state quantum information science and technology. Using first-principles calculations, we propose that lar…
