Ultrafast Dynamics of Coherent Phonon Modes in Excitonic Insulator TaNiSe
Vikas Arora, Sukanya Pal, Luminita Harnagea +2
The spontaneous condensation of excitons in the excitonic insulating phase has been reported in TaNiSe below 325 K. In this context, we present the temperature-dependent op…
Pressure Dependence of Ultrafast Carrier Dynamics in Excitonic Insulator TaNiSe
Vikas Arora, Victor S Muthu, Arijit Sinha +3
An excitonic insulator (EI) phase is a consequence of collective many-body effects where an optical band gap is formed by the condensation of electron-hole pairs or excitons. We re…
Ultrafast Spectroscopy of Dirac Semimetal Cd3As2 under Pressure
Vikas Arora, D. V. S. Muthu, R Sankar +1
Topological properties of a three-dimensional Dirac semimetal Cd3As2, protected by crystal rotation and time-reversal symmetry, can be tuned with the application of pressure. Ultra…
Raman and first-principles study of the pressure induced Mott-insulator to metal transition in bulk FePS
Subhadip Das, Shashank Chaturvedi, Debashis Tripathy +6
Recently discovered class of 2D materials based on transition metal phosphorous trichalcogenides exhibit antiferromagnetic ground state, with potential applications in spintronics.…
Pressure-induced 1T to 3R structural phase transition in metallic VSe2: X-ray diffraction and first-principles theory
Srishti Pal, Koyendrila Debnath, Satyendra Nath Gupta +4
We study pressure-induced structural evolution of vanadium diselenide (VSe2), a 1T polymorphic member of the transition metal di-chalcogenide (TMD) family using synchrotron-based p…
Tuning the structure of Skyrmion lattice system Cu2OSeO3 under pressure
Srishti Pal, Pallavi Malavi, Shashank Chaturvedi +5
The insulating ferrimagnet Cu2OSeO3 shows a rich variety of phases such as skyrmion lattice and helical magnetism controlled by interplay of different exchange interactions which c…
