Origin of the Background Absorption in Carbon Nanotubes: Phonon-Assisted Excitonic Continuum
Stefano Dal Forno, Natsumi Komatsu, Michael Wais +8
Excitonic effects in 1D semiconductors can be qualitatively different from those in higher dimensions. In particular, the Sommerfeld factor, the ratio of the above-band-edge excito…
Comparing scattering rates from Boltzmann and dynamical mean-field theory
M. Wais, J. Kaufmann, M. Battiato +1
We compute scattering rates for electrons in the two-dimensional Hubbard model for a one-orbital metal and a two-orbital band insulator by means of the Boltzmann scattering equatio…
Terahertz Excitonics in Carbon Nanotubes: Exciton Autoionization and Multiplication
Filchito Renee G. Bagsican, Michael Wais, Natsumi Komatsu +10
Excitons play major roles in optical processes in modern semiconductors, such as single-wall carbon nanotubes (SWCNTs), transition metal dichalcogenides, and 2D perovskite quantum…
Numerical solver for the time-dependent far-from-equilibrium Boltzmann equation
Michael Wais, Karsten Held, Marco Battiato
The study of strongly out-of-equilibrium states and their time evolution towards thermalization is critical to the understanding of an ever widening range of physical processes. We…
Quantum Boltzmann equation for strongly correlated systems: comparison to dynamical mean field theory
Michael Wais, Martin Eckstein, Roland Fischer +3
We investigate the potential of a quantum Boltzmann equation without momentum conservation for description of strongly correlated electron systems out of equilibrium. In a spirit s…
