Carrier thermalization and zero-point bandgap renormalization in halide perovskites from the Urbach tails of the emission spectrum
Kingshuk Mukhuti, Arnab Mandal, Basabendra Roy +2
We develop techniques to study the temperature dependent localization, thermalization, and the effects of phonon scattering on the excitons in halide perovskites from the analysis…
Nonlinear optical responses of all-inorganic lead halide perovskite nanostructures by time-resolved beam-deflection technique
Samrat Roy, Arnab Mandal, Akshay Raj R. +2
We have investigated nonlinear refraction in all-inorganic halide perovskites, the CsPbBr and CsPbBrI nanosheet and quantum dot colloids in toluene, by a novel…
Quantum symmetry of graph C*-algebras at critical inverse temperature
Arnab Mandal, Soumalya Joardar
We give a notion of quantum automorphism group of graph C*-algebras without sink at critical inverse temperature. This is defined to be the universal object of a category of CQG's…
Example of a group whose quantum isometry group does not depend on the generating set
Arnab Mandal
In this article we have shown that the quantum isometry group of , denoted by as in \cite{gos_man}, with respect to a symmetric genera…
