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…

Topological obstructed atomic limit by annihilating Dirac fermions
Santosh Kumar Radha, Walter R. L. Lambrecht
We show that annihilating a pair of Dirac fermions implies a topological transition from the critical semi-metallic phase to an Obstructed Atomic Limit (OAL) insulator phase instea…
