On atomic nuclear fusion processes at low temperatures. Enhancement of potential barrier transmission probability due to the so-called barrier anti-Zeno effect

Abstract

It is known that in quantum mechanics the observation of an experiment may in some cases change the results of this experiment. In particular, this occurs for the so-called Zeno effect. It is shown that, unlike the standard Zeno effect for which observation reduces its probability, for a particle that penetrates a potential barrier the opposite situation (called the barrier anti-Zeno effect) can occur, i.e., observation can considerably increase the probability of barrier penetration. The possibility of utilizing the barrier anti-Zeno effect for explaining the paradoxical results of experiments on “cold nuclear fusion” that have been observed in various, including biological, systems is discussed. (According to the experimentalists who performed such studies, in these systems energy release that cannot be explained by any chemical processes, as well as changes of the isotope and even elemental composition of the studied substance, occur).

[On Atomic Nuclear Fusion Processes at Low-Temperatures. An Enhancement of the Probability of Transition through a Potential Barrier Due to the So-Called Barrier Anti-Zeno Effect].

It is known that in quantum mechanics the act of observing the experiment can affect the experimental findings in some cases. In particular, it happens under the so-called Zeno effect. In this work it is shown that in contrast to the "standard" Zeno-effect where the act of observing a process reduces the probability of its reality, an inverse situation when a particle transmits through a potential barrier (a so-called barrier anti-Zeno effect) can be observed, the observation of the particle essentially increases the probability of its transmission through the barrier. The possibility of using the barrier anti-Zeno effect is discussed to explain paradoxical results of experiments on "cold nuclear fusion" observed in various systems including biological ones. (According to the observers who performed the observations, the energy generation, which could not be explained by any chemical processes, as well as the change in the isotope and even element composition of the studied object may occur in these systems.

On Enhancement of Transmission Probability through a High Potential Barrier Due to an Anti-Zeno Effect

Vladimir A. Namiot, Ljudmila Yu. Shchurova

We consider a situation in which observations themselves can significantly increase a particle transmission probability through a high barrier compared with the particle tunneling probability (a barrier anti-Zeno effect). This may explain the results of cold fusion experiments that have been reported by other authors for various systems. We examine the anti-Zeno effect as a model of a barrier of a special shape, which is similar to the form of barriers to nuclear fusion in a solid, and moreover, has an analytic solution. We have deduced formulas that demonstrate conditions that increase the barrier permeability. Numerical estimates of the particle flows through the barrier are carried out for the conditions of cold fusion experiments.

On a barrier anti-Zeno effect in a special model allowing for an analytical solution

Vladimir A. Namiot, Ljudmila Yu. Shchurova

We consider a situation when observations can increase particle flow across a barrier by many orders of magnitude compared with the tunneling probability (a barrier anti-Zeno effect). It may be of interest for explaining the paradoxical results of experiments on “cold fusion” that has earlier been observed by other authors for various systems. We examine the anti-Zeno effect in a model of a barrier of a special shape, which has similarities with the form of barriers to nuclear fusion in a solid, and moreover has an analytic solution. We have deducted formulas that demonstrate the conditions of increasing the barrier permeability.

On the Influence of Observation of the Processes in Quantum Systems: Is it Possible to Determine an Observer Effect in Biological Systems?

Vladimir A. Namiot, Ljudmila Yu. Shchurova

Abstract—The issue of how observation of a process in quantum mechanics may influence its outcome is described by case studies of quantum emission by a two-level system and the passage of a particle through a potential barrier. In the first case, the observation can reduce the probability of quantum emission by the two-level system (the quantum Zeno effect). In the second case, the observation of a particle can significantly increase the probability for a particle to pass through a barrier, sometimes even by many orders of magnitude (the barrier anti-Zeno effect). The possibility of such effects in biological systems is discussed.

New Explanation of the Physics of Tunnel Effect Processes

Viktar Yatskevich

The tunnel effect, commonly defined as the phenomenon in which a microparticle overcomes a potential barrier that exceeds its total energy, is often cited in quantum mechanics. However, this effect does not actually occur in its described form in nature, and the quantum mechanical interpretation of tunneling does not accurately represent the real physical processes involved, but rather provides a mathematical model. The true physical mechanism of the tunnel effect remains unidentified. An analysis of the tunnel effect reveals that its manifestation creates a “paradox” in classical physics. Explanations based on the Heisenberg uncertainty principle and the wave nature of particles fail to offer a comprehensive understanding of the actual physical process.This study proposes a new explanation of the tunneling phenomenon based on the principles of classical physics and electrodynamics. It is shown that the overcoming of the Coulomb barrier by low-energy microparticles occurs exclusively due to brief localized decreases in potential within the Coulomb barrier, allowing certain charged microparticles to penetrate. The formation mechanism of these short-lived localized regions, which manifest as volume channels with lower potential within the Coulomb barrier, is examined.It is established that the creation of these channels is linked to the properties of atomic nuclear and their associated electric fields. This facilitates the supra barrier penetration of the Coulomb barrier by individual low-energy microparticles that pass through these channels while experiencing a reduction in their total energy. This explanation resolves the “paradox” of the tunneling effect, eliminating the contradiction with classical physics laws.Moreover, the derived estimates of the tunneling process parameters are in qualitative agreement with the results obtained from quantum-mechanical models. The proposed framework aligns with nuclear physics findings, is supported by experimental evidence, and provides a new mechanism for controlling the tunneling effect in various energy-related applications.

Zeno and anti-Zeno effects in two-level systems

Alfredo Luis

We examine the appearance of Zeno and anti-Zeno effects when the unitary evolution of a two-level system is observed. We demonstrate that, contrary to previous claims, the anti-Zeno effect can occur in two-level systems so that the observation can enhance the transition probability. Moreover, for nonresonant couplings we show that the Zeno and anti-Zeno effects always appear sequentially in the evolution of the same system: there is Zeno effect in the short-time regime and anti-Zeno effect in the long-time regime.
