Anomalous Amplitude Mode Dynamics Below the Expected Charge‐Density‐Wave Transition in 1T‐VSe2

Anomalous Amplitude Mode Dynamics Below the Expected Charge‐Density‐Wave Transition in 1T‐VSe2

Abstract A charge‐density‐wave (CDW) is characterized by a dynamical order parameter consisting of a time‐dependent amplitude and phase, which manifest as optically‐active collective modes of the CDW phase. Studying the behavior of such collective modes in the time‐domain, and their coupling with el...
