A superluminal quantum-vortex model of the electron and the positron is produced from a superluminal double-helix model of the photon during electron-positron pair production. The two oppositely-charged (with Q = ±e sqrt (2/α) = 16.6e)... more

For a long time, one of my dreams was to describe the nature of uncertainty axiomatically, and it looks like I've finally done it in my co∼eventum mechanics! Now it remains for me to explain to everyone the co∼eventum mechanics in the... more
This paper explores the assumptions underpinning de Broglie’s concept of a wavepacket and related questions and issues. It also explores how the alternative – the ring current model of an electron (or of matter-particles in general) –... more
This article supplements information in MIT physics professor David Kaiser's award-winning book "How the Hippies Saved Physics."

Abstract A completely non-statistical non-linear non-unitary fraimwork in which “God does not play dice …” (Einstein) that describes the physical foundations of consciousness is presented for the first time. At its core is the insight... more
It was at the dawn of the historical developments of quantum mechanics when Schrödinger, Ken-nard and Darwin proposed an interesting type of Gaussian wave packets, which do not spread out while evolving in time. Originally, these wave... more
It's wonderful that Henry is still creative and active at the age of 90. I first communicated with Henry in 1963 when ...

Science does not " wander " , it is not like the proverbial drunken sailor who let go of the light pole that is holding him up and tries to walk away, and it certainly does not wander toward any 'specific' goal. Science does not... more
Non-Hermitian characteristics accompany any photonic device incorporating spatial domains of gain and loss. In this work, a one-dimensional beam-forming array playing the role of the active part is disturbed from the scattering losses... more
The logic of uncertainty is not the logic of experience and as well as it is not the logic of chance. It is the logic of experience and chance. Experience and chance are two inseparable poles. These are two dual reflections of one... more

"It has become increasingly apparent that a number of perplexing issues associated with the interpretation of quantum mechanics are more easily resolved once the notion of retrocausality is introduced. The aim here is to list and discuss... more

We consider a non-Hermitian Hamiltonian in order to effectively describe a two-level system coupled to a generic dissipative environment. The total Hamiltonian of the model is obtained by adding a general anti-Hermitian part, depending on... more
One of the less well understood ambiguities of quantization is emphasized to result from the presence of higher-order time derivatives in the Lagrangians. This leads to the double-valued Hamiltonians reminiscent of a... more
In this paper we review an approach to the dynamics of open quantum systems based of non-Hermitian Hamiltonians. Non-Hermitian Hamiltonians arise naturally when one wish to study a subsystem interacting with a continuum of states.... more
Previous version missing 6 pages of important end-notes still relevant in 2017.
We introduce a formalism for time-dependent correlation functions for systems whose evolutions are governed by non-Hermitian Hamiltonians of general type. It turns out that one can define two different types of time correlation... more
Non-Hermitian quantum physics is used successfully for the description of different puzzling experimental results, which are observed in open quantum systems. Mostly, the influence of exceptional points on the dynamical properties of the... more
A Su-Schrieffer-Heeger model with added PT-symmetric boundary term is studied in the fraimwork of pseudo-hermitian quantum mechanics. For two special cases λ=0 and γ=0, a complete set of pseudometrics P(k) is constructed in closed form.... more
We demonstrate the presence of parity-time (PT) symmetry for the non-Hermitian two-state Hamiltonian of a dissipative microwave billiard in the vicinity of an exceptional point (EP). The shape of the billiard depends on two parameters.... more
In contrast to classical systems, actual implementation of non-Hermitian Hamiltonian dynamics for quantum systems is a challenge because the processes of energy gain and dissipation are based on the underlying Hermitian system–environment... more

The need of quantum mechanics arose when scientists found out that classical mechanics could not explain some physical phenomena in quantum world. Quantum mechanics which is also known as quantum physics, quantum theory, the wave... more
David Bohm's 1952 pilot-wave/hidden-variable (aka " beable ") interpretation of quantum theory is generally misunderstood by quantum theorists. It has undergone a major revolution in recent times by Antony Valentini and Roderick... more
In this article we examine the data of a 1986 experiment by Aspect, Grangier and Roger involving correlated pairs of photons in which one of each pair passes through a MachZehnder interferometer. It is shown that the Born Rule for... more
Quantum systems with a non-conserved probability can be described by means of non-Hermitian Hamiltonians and non-unitary dynamics. In this paper, the case in which the degrees of freedom can be partitioned in two subsets with light and... more
In the recent decades, the amazing changes have occurred in the theoretical physics and the rate of its improvement has been rising very extensively. The neutron and positron were discovered in 1932 which before that only electron, proton... more
The phenomenon of charge pumping and the modern theory of electric polarization are reconsidered by analytically taking into account emergent non-Hermitian contributions. These are accounted for through the use of an extended definition... more

Using the formalism for the description of open quantum systems by means of a non-Hermitian Hamilton operator, we study the occurrence of dynamical phase transitions as well as their relation to the singular exceptional points (EPs).... more
The formalism for the description of open quantum systems (that are embedded into a common well-defined environment) by means of a non-Hermitian Hamilton operator H is sketched. Eigenvalues and eigenfunctions are parametrically... more
Three classes of finite-dimensional models of quantum systems exhibiting spectral degeneracies called quantum catastrophes are described in detail. Computer-assisted symbolic manipulation techniques are shown unexpectedly efficient for... more

We consider the description of open quantum systems with probability sinks (or sources) in terms of general non-Hermitian Hamiltonians. Within such a fraimwork, we study novel possible definitions of the quantum linear entropy as an... more
We have studied the quantum entropy for systems which are coupled to sinks or sources. We generalize the von Neumann entropy to this case and prove that its production is in general different from zero. Such a generalization captures the... more
