Passage through fluctuating geometrical bottlenecks. Subdiffusive dynamics of the opening -- exact solution
K L Sebastian
The usual Kramers theory of reaction rates in a condensed medium predict the rate to have an dependence, being the viscosity of the medium. However, experiments on lig…
Unusual eigenvalue spectrum and relaxation in the Lévy Ornstein-Uhlenbeck process
Deepika Janakiraman, K. L. Sebastian
We consider the rates of relaxation of a particle in a harmonic well, subject to Lévy noise characterized by its Lévy index . Using the propagator for this Lévy Ornstein-Uhlenbe…
Analytical Treatment of Coherent Excitation Transfer in FMO Complex
Pallavi Bhattacharyya, K. L. Sebastian
We suggest a new method of studying coherence in finite level systems coupled to the environment and use it for the Hamiltonian that has been used to describe the light-harvesting…
Path Integral Formulation for Lévy Flights - Evaluation of the Propagator for Free, Linear and Harmonic Potentials in the Over- and Underdamped Limits
Deepika Janakiraman, K. L. Sebastian
Lévy flights can be described using a Fokker-Planck equation which involves a fractional derivative operator in the position co-ordinate. Such an operator has its natural expressio…
Dynamics of pulled desorption with effects of excluded volume interaction: The p-Laplacian diffusion equation and its exact solution
K. L. Sebastian, V. G. Rostiashvili, T. A. Vilgis
We analyze the dynamics of desorption of a polymer molecule which is pulled at one of its ends with force , trying to desorb it. We assume a monomer to desorb when the pulling f…
Conductance of a photochromic molecular switch with graphene leads
C. Motta, M. I. Trioni, G. P. Brivio +1
We report a full self-consistent ab initio calculation of the conductance of a diarylethene-based molecular switch with two graphene electrodes. Our result show the contributions o…
