Variable Range Hopping Conduction in Complex Systems and a Percolation Model with Tunneling
Asok K. Sen, Somnath Bhattacharya
For the low-temperature electrical conductance of a disordered {\it quantum insulator} in -dimensions, Mott \cite{mott} had proposed his Variable Range Hopping (VRH) formula, $G…
Two early-stage inverse power-law dyamics in nonlinear complex systems far-from equilibrium
Somnath Bhattacharya, Asok K. Sen
We consider the dynamics of the charge carriers in a tunneling-enhanced percolation network, named as a Random Resistor cum Tunneling-bond Network (RRTN), where we allow tunneling…
Two early stage inverse power-law relaxations in the far from equilibrium dynamics in semi-classical percolative composites
Somnath Bhattacharya, Partha Pratim Roy, Asok Kumar Sen
In several experiments for measuring various classes of responses, performed at least some four decades ago, on driven physical systems in a far-from-equilibrium (or, from a steady…
Electronic transport in a randomly amplifying and absorbing chain
Asok K. Sen
We study localization properties of a one-dimensional disordered system characterized by a random non-hermitean hamiltonian where both the randomness and the non-hermiticity arises…
