Spin-phonon interaction in a symmetry-enforced spin-polarized state
Suman Kalyan Pradhan, Dayal Das, Shubham Patel +8
Symmetry-governed magnetic materials have emerged as a promising platform for spintronic functionalities without net magnetization or stray magnetic fields, motivating the explorat…
Spin Reorientation Driven Renormalization of Spin-Phonon Coupling in FeGeTe
Riju Pal, Md. Nur Hasan, Chumki Nayak +9
Quasi-2D van der Waals ferromagnet FeGeTe, featuring the simultaneous presence of high Curie temperature ( K) and a spin-reorientation transition a…
Brightening of dark trions in monolayer WS via localization of surface plasmons
Sreyan Raha, Tara Shankar Bhattacharya, Indrani Bose +1
Among all excitonic complexes in transition-metal dichalcogenides (TMDs), dark and semi-dark trions are poised to play a stellar role in future quantum technologies due to their lo…
Alloying as a new route to generating interlayer excitons
Suvadip Masanta, Chumki Nayak, Premananda Chatterjee +3
Heterobilayers formed by stacking two-dimensional atomic crystals are particularly promising for low-dimensional semiconductor optics, as they host interlayer excitons, bound state…
Lattice dynamics of topological Dirac semimetal LaAgSb with charge density wave ordering
Ratnadwip Singha, Sudeshna Samanta, Tara Shankar Bhattacharya +5
LaAgSb is a rare material, which offers the opportunity to investigate the complex interplay between charge density wave (CDW) ordering and topology protected electronic band…
