Fermi Liquid Theory Sheds Light on "Hot" EHL in 1L-MoS
R. L. Wilmington, H. Ardekani, A. Rustagi +4
2D transition metal dichalcogenides (TMDCs) exhibit an electron-hole liquid phase transition at unusually high temperatures. Because these materials are atomically thin, optical ex…
Observing coherences with time-resolved photoemission
Alexander F. Kemper, Avinash Rustagi
We discuss the potential creation and measurement of coherences in both dispersive solids and qubit-like single levels using current generation time- and angle-resolved photoemissi…
Nonequilibrium dynamics of spontaneous symmetry breaking into a hidden state of charge-density wave
Faran Zhou, Joseph Williams, Christos D. Malliakas +3
Nonequilibrium phase transition plays a pivotal role in a broad physical context from condensed matter to cosmology. Tracking the formation of non-equilibrium phases in condensed m…
Coherent Excitonic Quantum Beats in Time-Resolved Photoemission Measurements
Avinash Rustagi, Alexander F. Kemper
Coherent excitation of materials via ultrafast laser pulses can have interesting, observable dynamics in time-resolved photoemission measurements. The broad spectral width of ultra…
Photoemission signature of excitons
Avinash Rustagi, Alexander F. Kemper
Excitons - the particle-hole bound states - composed of localized electron-hole states in semiconducting systems are crucial to explaining the optical spectrum. Spectroscopic measu…
Relationship between Population Dynamics and the Self-Energy in Driven Non-Equilibrium Systems
Alexander F. Kemper, James. K. Freericks
We compare the decay rates of excited populations directly calculated within a Keldysh formalism to the equation of motion of the population itself for a Hubbard-Holstein model in…
