Continuous-time statistics and generalized relaxation equations [PDF]

open access: yes, 2017
Using two simple examples, the continuous-time random walk as well as a two state Markov chain, the relation between generalized anomalous relaxation equations and semi-Markov processes is illustrated. This relation is then used to discuss continuous-time random statistics in a general setting, for statistics of convolution-type.

The Statistical Physics of Athermal Materials [PDF]

open access: yes, 2014
At the core of equilibrium statistical mechanics lies the notion of statistical ensembles: a collection of microstates, each occurring with a given a priori probability that depends only on a few macroscopic parameters such as temperature, pressure ...

Statistical physics of inference: thresholds and algorithms [PDF]

open access: yesarXiv.org, 2015
Many questions of fundamental interest in today's science can be formulated as inference problems: some partial, or noisy, observations are performed over a set of variables and the goal is to recover, or infer, the values of the variables based on the ...

A Differential-Geometric Approach to Quantum Ignorance Consistent with Entropic Properties of Statistical Mechanics

open access: yesEntropy, 2023
In this paper, we construct the metric tensor and volume for the manifold of purifications associated with an arbitrary reduced density operator ρS. We also define a quantum coarse-graining (CG) to study the volume where macrostates are the manifolds of ...

Deformation of Crystals: Connections with Statistical Physics [PDF]

open access: yes, 2016
We give a bird's-eye view of the plastic deformation of crystals aimed at the statistical physics community, as well as a broad introduction to the statistical theories of forced rigid systems aimed at the plasticity community. Memory effects in magnets,

Stochastic Spatial Models in Ecology: A Statistical Physics Approach [PDF]

open access: yesJournal of statistical physics, 2017
Ecosystems display a complex spatial organization. Ecologists have long tried to characterize them by looking at how different measures of biodiversity change across spatial scales. Ecological neutral theory has provided simple predictions accounting for

Basin stability for chimera states

open access: yesScientific Reports, 2017
Chimera states, namely complex spatiotemporal patterns that consist of coexisting domains of spatially coherent and incoherent dynamics, are investigated in a network of coupled identical oscillators.

Entropies for severely contracted configuration space

open access: yesHeliyon, 2015
We demonstrate that dual entropy expressions of the Tsallis type apply naturally to statistical–mechanical systems that experience an exceptional contraction of their configuration space.

A Physicist’s View on Partial 3D Shape Matching

open access: yesAlgorithms, 2023
A new algorithm is presented to compute nonrigid, possibly partial comparisons of shapes defined by unstructured triangulations of their surfaces.

Painlev\'e Functions in Statistical Physics

open access: yes, 2009
We review recent progress in limit laws for the one-dimensional asymmetric simple exclusion process (ASEP) on the integer lattice. The limit laws are expressed in terms of a certain Painlev\'e II function.
