Time quantization and q-deformations

We extend to quantum mechanics the technique of stochastic subordination, by means of which one can express any semi-martingale as a time-changed Brownian motion. As examples, we considered two versions of the q-deformed harmonic oscillator in both ordinary and imaginary time and show how these various cases can be understood as different patterns of time quantization rules.

Poisson Bracket in Non-commutative Algebra of Quantum Mechanics

The widely accepted approach to the foundation of quantum mechanics is that the Poisson bracket, governing the non-commutative algebra of operators, is taken as a postulate with no underlying

Chronons, Time Atoms, and Quantized Time: Time Asymmetry Re-Visited

A directional time does not feature in Newtonian mechanics, in electromagnetic theory, in quantum mechanics, in the equations which describe the world of elementary particles (with the exception of


An alternative wavefunction to the description of the dynamic localization of a charged particle moving on a one-dimensional lattice under the influence of a periodic time dependent electric field is

A Modular Operator Approach to Entanglement of Causally Closed Regions

Quantum entanglement is shown for causally separated regions along the radial direction by using a conformal quantum mechanical correspondence with conformal radial Killing fields of causal diamonds

Bochner Subordination, Logarithmic Diffusion Equations, and Blind Deconvolution of Hubble Space Telescope Imagery and Other Scientific Data

A powerful blind deconvolution procedure based on postulating system optical transfer functions (otfs) in the form of generalized Linnik characteristic functions is developed, resolving the unexplained appearance of exceptionally low Levy stable exponents in previous work on the same class of images.

The Universe is Like a Hollowed Sphere. The Wave Concept of Time

There is space for new ideas of the essence and the entity of time. The article refers to our time concept as a special wave type and presents results of our investigations on this subject. Thus,



Quantum and classical mechanics of Q deformed systems

Quantum and classical mechanics of a system of q-deformed bosonic oscillators are considered. The q-deformed Heisenberg-Weyl algebra of creation and destruction operators is realized by differential

The quantum group SUq(2) and a q-analogue of the boson operators

A new realisation of the quantum group SUq(2) is constructed by means of a q-analogue to the Jordan-Schwinger mapping, determining thereby both the complete representation structure and q-analogues

Introduction of a quantum of time (chronon), and its consequences for quantum mechanics

In this review-article, we discuss the consequences of the introduction of a quantum of time tau_0 in the formalism of non-relativistic quantum mechanics (QM) by referring ourselves in particular to

On spectral properties ofq-oscillator operators

AbstractThe property of self-adjointness of the operatorQ =a+ +a- in three types ofq-oscillator algebras is considered. Spectral measures and generalized eigenfunctions ofQ are found in the cases

Hilbert spaces of analytic functions and generalized coherent states

Generalized coherent states which are associated with a generalization of the harmonic oscillator commutation relation are investigated. It is shown that these states form an overcomplete basis in a

WKB equivalent potentials for the q-deformed harmonic oscillator

WKB equivalent potentials (WKB-EP) giving the same spectrum as the q-deformed harmonic oscillator with the symmetry SUq(2) are determined. While in the case of q being real the WKB-EP goes to
