Real space renormalization group for Ising Spin Glass and other glassy models. I. Disordered Ising model. General formalism
A. N. Samukhin
Here is the first part of the summary of my work on random Ising model using real-space renormalization group (RSRG), also known as a Migdal-Kadanoff one. This approximate renormal…
On dispersive energy transport and relaxation in the hopping regime
O. Bleibaum, H. Böttger, V. V. Bryksin +1
A new method for investigating relaxation phenomena for charge carriers hopping between localized tail states has been developed. It allows us to consider both charge and energy {\…
Hopping Conductivity of a Nearly-1d Fractal: a Model for Conducting Polymers
A. N. Samukhin, V. N. Prigodin, L. Jastrabik +1
We suggest treating a conducting network of oriented polymer chains as an anisotropic fractal whose dimensionality D=1+εis close to one. Percolation on such a fractal is studied wi…
Conductivity fluctuations in polymer's networks
A. N. Samukhin, V. N. Prigodin, L. Jastrabik
Polymer's network is treated as an anisotropic fractal with fractional dimensionality D = 1 + εclose to one. Percolation model on such a fractal is studied. Using the real space re…
Critical Percolation and Transport in Nearly One Dimension
A. N. Samukhin, V. N. Prigodin, L. Jastrabik +1
A random hopping on a fractal network with dimension slightly above one, , is considered as a model of transport for conducting polymers with nonmetallic conductivity. W…
