Ultrafast Dynamics of Coherent Phonon Modes in Excitonic Insulator Ta $_{2}$ NiSe $_{5}$

Vikas Arora, Sukanya Pal, Luminita Harnagea +2

The spontaneous condensation of excitons in the excitonic insulating phase has been reported in Ta $_{2}$ NiSe $_{5}$ below 325 K. In this context, we present the temperature-dependent op…

Pressure Dependence of Ultrafast Carrier Dynamics in Excitonic Insulator Ta $_{2}$ NiSe $_{5}$

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…
