Non-stochastic matrix Schrödinger equation for open systems
Loïc Joubert-Doriol, Ilya G. Ryabinkin, Artur F. Izmaylov
We propose an extension of the Schrödinger equation for a quantum system interacting with environment. This equation describes dynamics of auxiliary wave-functions , fr…
A perturbative formalism for electronic transitions through conical intersections in a fully quadratic vibronic model
Julia S. Endicott, Loic Joubert-Doriol, Artur F. Izmaylov
We consider a fully quadratic vibronic model Hamiltonian for studying photoinduced electronic transitions through conical intersections. Using a second order perturbative approxima…
When do we need to account for the geometric phase in excited state dynamics ?
Ilya G. Ryabinkin, Loic Joubert-Doriol, Artur F. Izmaylov
We investigate the role of the geometric phase (GP) in an internal conversion process when the system changes its electronic state by passing through a conical intersection (CI). L…
Irradiation Instability at the Inner Edges of Accretion Disks
Jeffrey Fung, Pawel Artymowicz
An instability can potentially operate in highly irradiated disks where the disk sharply transitions from being radially transparent to opaque (the 'transition region'). Such condi…
