Ferroelastic exciton splitting in hybrid perovskite nanowalls
Afreen, J. Delgado-Alvarez, H. Krishna Mishra +9
Hybrid metal-halide perovskites are soft semiconductors in which electronic excitations are strongly influenced by lattice distortions and structural phase transitions. An importan…
Emergent Quantum Walk Dynamics from Classical Interacting Particles
Surajit Saha
The dynamics of a discrete-time quantum walk (DTQW) can be realized within a purely classical interacting particle system composed of some boxes and a large but finite number of ba…
Evidence of spin-phonon-charge coupling in quasi-one-dimensional Ising spin chain system -CoVO
Debismita Naik, Souvick Chakraborty, Akriti Singh +5
The quasi-one-dimensional Ising spin chain system -CoVO is considered to exhibit fascinating magnetic properties at lower temperatures. We comprehensively study magneti…
Electron-phonon interactions and tensor analysis in topological insulator bismuth telluride using angle resolved polarized Raman spectroscopy
Aditya Singh, Anna Elsukova, Divya Rawat +6
We report on the angle-resolved polarized Raman spectroscopy and estimation of the Raman tensor elements using both classical and quantum treatments to analyse the polarized Raman…
Defect-mediated electron-phonon coupling in halide double perovskite
Aprajita Joshi, Sajid Saikia, Shalini Badola +2
Optically active defects often play a crucial role in governing the light emission as well as the electronic properties of materials. Moreover, defect-mediated states in the mid-ga…
