Band resolved imaging of photocurrent in a topological insulator
Hadas Soifer, Alexandre Gauthier, Alexander F. Kemper +8
We study the microscopic origins of photocurrent generation in the topological insulator BiSe via time- and angle-resolved photoemission spectroscopy. We image the unoccupi…
Theoretical phase diagram for the room temperature Electron-Hole Liquid in photo-excited quasi-2D monolayer MoS
Avinash Rustagi, Alexander F. Kemper
Strong correlations between electrons and holes can drive the existence of an electron-hole liquid (EHL) state, typically at high carrier densities and low temperatures. The recent…
General principles for the non-equilibrium relaxation of populations in quantum materials
A. F. Kemper, O. Abdurazakov, J. K. Freericks
We examine the problem of how excited populations of electrons relax after they have been excited by a pump. We include three of the most important relaxation processes: (i) impuri…
Dynamics of correlation-frozen antinodal quasiparticles in superconducting cuprates
Federico Cilento, Giulia Manzoni, Andrea Sterzi +15
Many puzzling properties of high- superconducting (HTSC) copper oxides have deep roots in the nature of the antinodal quasiparticles, the elementary excitations with wavevecto…
