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 magnetic…
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…

Abhinav Kumar Khorwal, Sonu Vishvakarma, Sujoy Saha +5
An extensive experimental investigation on the structural, static magnetic, and non-equilibrium dynamical properties of polycrystalline MnCuGe Heusler alloy using powder X-ray…
Signatures of novel magnon-phonon coupling in frustrated double perovskite square lattices
Shalini Badola, Aprajita Joshi, Akriti Singh +1
Low-dimensional frustrated magnetic square networks feature a variety of unconventional phases with novel emergent excitations. Often these excitations are intertwined and manifest…
Emergence of a spin-liquid-like phase in quantum spin-ladder Ba2CuTeO6 with chemical substitution
Shalini Badola, Devesh Negi, Aprajita Joshi +1
Stabilization of the quantum spin liquids is vital to realize applications in spintronics and quantum computing. The unique magnetic structure of Ba2CuTeO6 comprising of coupled sp…
Tailoring the defects and electronic band structure in WS2/h-BN heterostructure
Suvodeep Paul, Saheb Karak, Saswata Talukdar +2
The 2D semiconducting transition metal dichalcogenides (e.g., WS2) host strong coupling between various degrees of freedom leading to potential applications in next-generation devi…
Spin-phonon coupling suppressing the structural transition in perovskite-like oxide
Shalini Badola, Supratik Mukherjee, Greeshma Sunil +5
Multifunctional properties in quantum systems require the interaction between different degrees of freedom. As such, spin-phonon coupling emerges as an ideal mechanism to tune mult…
