Fixman problem revisited: When fluctuations of inflated ideal polymer loop are non-Gaussian?
Sergei Nechaev, Alexander Valov
We consider statistics of a planar ideal polymer loop of length in a large deviation regime, when a gyration radius, , is slightly less than the radius of a fully inflated…
Field-driven tracer diffusion through curved bottlenecks: Fine structure of first passage events
A. Valov, V. Avetisov, S. Nechaev +1
Using scaling arguments and extensive numerical simulations, we study dynamics of a tracer particle in a corrugated channel represented by a periodic sequence of broad chambers and…
Ultrametric theory of conformational dynamics of protein molecules in a functional state and the description of experiments on the kinetics of CO binding to myoglobin
A. Kh. Bikulov, A. P. Zubarev
The paper is devoted to a systematic account of the theory of conformational dynamics of protein molecules. As an example of application of this theory, we provide a complete analy…
Anomalous 1D fluctuations of a simple 2D random walk in a large deviation regime
Sergei Nechaev, Kirill Polovnikov, Senya Shlosman +2
The following question is the subject of our work: could a two-dimensional random path pushed by some constraints to an improbable "large deviation regime", possess extreme statist…

V. Kovaleva, Yu. Maximov, S. Nechaev +1
In this paper we investigate the eigenvalue statistics of exponentially weighted ensembles of full binary trees and -branching star graphs. We show that spectral densities of co…
Paths counting on simple graphs: from escape to localization
S. K. Nechaev, M. V. Tamm, O. V. Valba
We study the asymptotic behavior of the number of paths of length on several classes of infinite graphs with a single special vertex. This vertex can work as an entropic trap f…
Heat conduction in a chain of colliding particles with stiff repulsive potential
O. V. Gendelman, A. V. Savin
One-dimensional billiard, i.e. a chain of colliding particles with equal masses, is well-known example of completely integrable system. Billiards with different particles are gener…

We consider the canonical ensemble of -vertex Erdős-Rényi (ER) random topological graphs with quenched vertex degree, and with fugacity for each closed triple of bonds. We c…
Normal heat conductivity in two-dimensional scalar lattices
A. V. Savin, V. Zolotarevskiy, O. V. Gendelman
The paper revisits recent counterintuitive results on divergence of heat conduction coefficient in two-dimensional lattices. It was reported that in certain lattices with on-site p…
