Ergodic theorem, ergodic theory, and statistical mechanics. [PDF]

open access: yesProc Natl Acad Sci U S A, 2015
This perspective highlights the mean ergodic theorem established by John von Neumann and the pointwise ergodic theorem established by George Birkhoff, proofs of which were published nearly simultaneously in PNAS in 1931 and 1932. These theorems were of great significance both in mathematics and in statistical mechanics.

The ergodic theory of AxiomA flows

open access: yesInventiones Mathematicae, 1975
Let M be a compact (Riemann) manifold and (f t ): M → M a differentiable flow. A closed (f t )-invariant set ∧ ⊂ M containing no fixed points is hyperbolic if the tangent bundle restricted to ∧ can be written as the Whitney sum of three (Tf t )-invariant continuous subbundles $${T_\Lambda }M = E + {E^s} + {E^u}$$ where E is the one-dimensional ...

Central Limit Theorem in View of Subspace Convex-Cyclic Operators [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
In our work we have defined an operator called subspace convex-cyclic operator. The property of this newly defined operator relates eigenvalues which have eigenvectors of modulus one with kernels of the operator.

Quantum chaos in 2D gravity

open access: yesSciPost Physics, 2023
We present a quantitative and fully non-perturbative description of the ergodic phase of quantum chaos in the setting of two-dimensional gravity. To this end we describe the doubly non-perturbative completion of semiclassical 2D gravity in terms of its ...

Theory of Ergodic Quantum Processes

open access: yesPhysical Review X, 2021
The generic behavior of quantum systems has long been of theoretical and practical interest. Any quantum process is represented by a sequence of quantum channels.

Dynamical quantum ergodicity from energy level statistics

open access: yesPhysical Review Research, 2023
Ergodic theory provides a rigorous mathematical description of chaos in classical dynamical systems, including a formal definition of the ergodic hierarchy. How ergodic dynamics is reflected in the energy levels and eigenstates of a quantum system is the

From operator statistics to wormholes

open access: yesPhysical Review Research, 2021
For a generic quantum many-body system, the quantum ergodic regime is defined as the limit in which the spectrum of the system resembles that of a random matrix theory (RMT) in the corresponding symmetry class.

On Two Non-Ergodic Reversible Cellular Automata, One Classical, the Other Quantum

open access: yesEntropy, 2023
We propose and discuss two variants of kinetic particle models—cellular automata in 1 + 1 dimensions—that have some appeal due to their simplicity and intriguing properties, which could warrant further research and applications.

Generalized Ordinal Patterns and the KS-Entropy

open access: yesEntropy, 2021
Ordinal patterns classifying real vectors according to the order relations between their components are an interesting basic concept for determining the complexity of a measure-preserving dynamical system. In particular, as shown by C. Bandt, G.
