Probability Thermodynamics and Probability Quantum Field

open access: yes, 2019
In this paper, we introduce probability thermodynamics and probability quantum fields. By probability we mean that there is an unknown operator, physical or nonphysical, whose eigenvalues obey a certain statistical distribution. Eigenvalue spectra define

On multiparameter spectral theory

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
A connection between the numerical range of the multipararneter linear system P(λ) and the joint numerical range of the (commuting) separating operator system is given.

Spectral integration and spectral theory for non-Archimedean Banach spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Banach algebras over arbitrary complete non-Archimedean fields are considered such that operators may be nonanalytic. There are different types of Banach spaces over non-Archimedean fields.

An introduction to the distorted Fourier transform

open access: yesAdvanced Nonlinear Studies
This article is intended as an introduction to the distorted Fourier transform associated with a Schrödinger operator on the line or the half-line. This versatile tool has seen numerous applications in nonlinear PDE in recent years.

On the Holographic Spectral Effects of Time-Interval Subdivisions

open access: yesQuantum Reports
Drawing on formal parallels between scalar diffraction theory and quantum mechanics, it is demonstrated that quantum wavefunction propagation requires a holographic model of time.

Spectral Rate Theory for Two-State Kinetics

open access: yesPhysical Review X, 2014
Classical rate theories often fail in cases where the observable(s) or order parameter(s) used is a poor reaction coordinate or the observed signal is deteriorated by noise, such that no clear separation between reactants and products is possible.
