Optical response and band structure of LiCoO2 including electron-hole interaction effects
Santosh Kumar Radha, Walter R. L. Lambrecht, Brian Cunningham +3
The optical response functions and band structures of LiCoO are studied at different levels of approximation, from density functional theory (DFT) in the generalized gradient a…
Quantum constraint learning for quantum approximate optimization algorithm
Santosh Kumar Radha
The quantum approximate optimization algorithm (QAOA) is a hybrid quantum-classical variational algorithm that offers the potential to handle combinatorial optimization problems. I…
Ultrathin 2D-oxides: a perspective on fabrication, structure, defect, transport, electron and phonon properties
Santosh Kumar Radha, Kyle Crowley, Brian A. Holler +7
In the field of atomically thin 2D materials, oxides are relatively unexplored in spite of the large number of layered oxide structures amenable to exfoliation. There is an increas…
Distortion modes in halide perovskites: to twist or to stretch, a matter of tolerance and lone pairs
Santosh Kumar Radha, Churna Bhandar, Walter R. L. Lambrech
Using first-principles calculations, we show that CsBX halides with B=Sn or Pb undergo octahedral rotation distortions, while for B=Ge and Si, they undergo a ferro-electric rho…
Quantum option pricing using Wick rotated imaginary time evolution
Santosh Kumar Radha
In this paper we reformulate the problem of pricing options in a quantum setting. Our proposed algorithm involves preparing an initial state, representing the option price, and the…
