Energies and lifetimes of electrons and excitons in Si20 modeled by many-body Green’s function theory
Published 2012“…The quasiparticle lifetimes in Si[subscript 20] are calculated by the GWΓ method and can be categorized into a high-energy regime and a low-energy regime. In the high-energy regime, the scaled lifetimes of electrons and holes in Si[subscript 20] are calculated to be 104 and 30 fs eV[superscript 2], respectively, which are close to the corresponding bulk theoretical values in the literature. …”

Probabilistic Description of Extreme Events in Intermittently Unstable Dynamical Systems Excited by Correlated Stochastic Processes
Published 2017“…The unstable regime is inherently transient, and in order to analyze this regime we characterize the statistics under the assumption of an exponential growth phase and a subsequent decay phase until the system is brought back to the stable attractor. …”

Anderson Localization of Thermal Phonons Leads to a Thermal Conductivity Maximum
Published 2017“…By analyzing the sample-to-sample fluctuations in the dimensionless conductance, g, the transition from diffusive to localized transport is identified as the crossover from the multichannel to single-channel transport regime g ≈ 1. Single parameter scaling is shown to hold in this crossover regime through the universality of the probability distribution of g that is independent of system size and disorder strength.…”

Confinement-induced stabilization of the Rayleigh-Taylor instability and transition to the unconfined limit
Published 2021“…With increasing spacing, the system transitions from the limit of stability where mass diffusion dominates over buoyant forces, through a regime where the gap sets the wavelength of the instability, to the unconfined regime governed by the competition between buoyancy and momentum diffusion. …”
