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…
Twist Angle Dependent Ultrafast Transient Dynamics of MoSe/WSe van der Waals Heterostructures beyond the Exciton Mott Transition
Vikas Arora, Pramoda K Nayak, Victor S Muthu +1
Two-dimensional van der Waals heterostructures (HS) exhibit twist-angle () dependent interlayer charge transfer, driven by moiré potential that tunes the electronic band structu…
