Magnetism at the interface of heterostructures
Rohin Sharma, Diem Thi-Xuan Dang, Lilia M. Woods
Magnetism in doped transition metal dichalcogenide monolayers and van der Waals interfaced materials have motivated the search for sustainable magnetic states at the nanoscale with…
Upconversion of infrared light by graphitic micro-particles due to photo-induced structural modification
Rohin Sharma, Nishma Bhattarai, Rijan Maharjan +3
Recent reports of upconversion and white light emission from graphitic particles warrant an explanation of the physics behind the process. We offer a model, wherein the upconversio…
Determining size of an optically trapped particle via modulated Raman spectroscopy
Rohin Sharma, Anusa Thapa, Rijan Maharjan +1
The average Raman signal power obtained in a modulated optical trap is dependent on the Brownian motion - therefore hydrodynamic properties of the trapped particle. Hence, in addit…
Relativistic Tight-Binding Model for Hexagonal Lattice: Application to Graphene
Rohin Sharma, Amit Shrestha, Masahiko Higuchi +2
A non-perturbative relativistic tight-binding (TB) approximation method applicable to crystalline material immersed in a magnetic field was developed in 2015. To apply this method…
