We present a comprehensive temperature and polarization dependent inelastic light scattering (Raman) study on single crystals of two-dimensional CuCrP2S6, a layered van der Waals m…
Exciton dynamics, Fano quantum interference and d-d excitation in the single crystal of two-dimensional antiferromagnetic Fe2P2S6
Nasaru Khan, Yuliia Shemerliuk, Sebastian Selter +3
Excitonic quasiparticle and their interactions with phonons, magnons and charge carriers may play a pivotal role in governing the optical properties and their correlation with magn…
Exciton dynamics and exciton-phonon coupling in bulk and thin flakes of layered van der Waals antiferromagnet NiPS
Nasaru Khan, Yuliia Shemerliuk, Sebastian Selter +3
The Zhang-Rice (ZR) singlet is an intriguing quantum state offering potential to realize a spin-orbit-entangled bosonic quasiparticle, which gives rise to the Zhang-Rice exciton. I…
Antipolar and short and long-range magnetic ordering in quasi-two-dimensional AgCrP2S6
Chaitanya B. Auti, Atul G. Chakkar, Shantanu Semwal +6
Within the Landau theoretical framework, the decreased entropy with decreasing the temperature is accompanied by the symmetry breaking and hence a corresponding phase transition. T…
