Robust Aluminum Nitride Passivation of Silicon Carbide with Near-Surface Quantum Emitters for Quantum Computing and Sensing Applications
Cyrille Armel Sayou Ngomsi, Sai Krishna Narayanan, Pratibha Dev
Silicon carbide (SiC) hosts a number of point defects that are being explored as single-photon emitters for quantum applications. Unfortunately, these quantum emitters lose their p…

Tuning spin currents in collinear antiferromagnets and altermagnets
Sajjan Sheoran, Pratibha Dev
Spin current generation through non-relativistic spin splittings, found in uncompensated magnets and d-wave altermagnets, is desirable for low-power spintronics. Such spin currents…

Spontaneous Anomalous Hall Effect in Two-Dimensional Altermagnets
Sajjan Sheoran, Pratibha Dev
The anomalous Hall effect (AHE) is an efficient tool for detecting the Néel vector in collinear compensated magnets with spin-split bands, known as altermagnets (AMs). Here, we es…
