Engineering Topology by Design in Two-dimensional Materials
Arjyama Bordoloi, Sobhit Singh
Two-dimensional topological insulators (2D TIs) have emerged as a cornerstone of next-generation spintronic technologies due to their robust, dissipationless edge states protected…
Probing the Nature of Interstitial Anionic Electrons in 2D Electride CaN via Landau-Level Spectroscopy
Arjyama Bordoloi, Daniel Kaplan, Sobhit Singh
We investigate the magnetic-field response of interstitial anionic electrons (IAEs) in two-dimensional electrides, using monolayer CaN as a prototypical system. By computing th…
Dominant in-plane anomalous Hall effect in a monoclinic room-temperature ferromagnet
Guoxin Zheng, Arjyama Bordoloi, Mingjun Fan +6
Ferromagnetic metals are characterized by enhanced dissipationless transverse transport responses via the anomalous Hall effect, offering a route towards magnetic sensing and spint…
Relaxation-driven topological domains in moiré materials
Arjyama Bordoloi, Daniel Kaplan, Sobhit Singh
Spatial control of topology is highly desirable for realizing tunable quantum functionalities in materials. Moiré superlattices formed by twisting van der Waals heterostructures pr…
