Extraordinary Lifetime Enhancement of Coherent Phonon-Amplitude Modes in the Excitonic Insulator Phase of Ta2Pd3Te5
Anjan Kumar N M, Shuhan Wang, Snehashish Chatterjee +9
The excitonic insulator (EI) is an electronic phase of condensed excitons. However, in many prototypical materials the presence of a concurrent structural transition complicates th…

Dynamics of Charge-Density-Wave puddles in 2-NbSe
Shreya Kumbhakar, Marina Esposito, Anjan Kumar N M +15
Electronic phases in quantum materials are often governed by nanoscale inhomogeneity, where local order develops within spatially confined regions or puddles. A prominent example i…
