Quantum-classical mechanics as an alternative to quantum mechanics in molecular and chemical physics

open access: yesHeliyon, 2019
In quantum mechanics, the theory of quantum transitions is grounded on the convergence of a series of time-dependent perturbation theory. In nuclear and atomic physics, this series converges because the dynamics of quantum transitions (quantum jumps) are

Experimental entanglement-assisted quantum delayed-choice experiment

open access: yes, 2014
The puzzling properties of quantum mechanics, wave-particle duality, entanglement and superposition, were dissected experimentally at past decades. However, hidden-variable (HV) models, based on three classical assumptions of wave-particle objectivity ...

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

Does God Cheat at Dice? Divine Action and Quantum Possibilities

open access: yesZygon, 2000
The recent debates concerning divine action in the context of quantum mechanics are examined with particular reference to the work of William Pollard, Robert J. Russell, Thomas Tracy, Nancey Murphy, and Keith Ward.

Observations of the Ramsauer–Townsend effect in quaternionic quantum mechanics

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In this article, one of the well-known effects in quantum mechanics is addressed and also the extended form of quantum mechanics which is based on quaternions is presented. In the presence of this version of quantum mechanics the Ramsauer–Townsend effect

Do atoms age?

open access: yesPhysics Letters B, 2022
Time evolution generically entangles a quantum state with environmental degrees of freedom. The resulting increase in entropy changes the properties of that quantum system leading to “aging”.

Classical mechanics is not h=0 limit of quantum mechanics

open access: yes, 2004
Both the set of quantum states and the set of classical states described by symplectic tomographic probability distributions (tomograms) are studied. It is shown that the sets have common part but there exist tomograms of classical states which are not ...

A Reconstruction of Quantum Mechanics [PDF]

open access: yesFoundations of Physics, 2015
We formulate a general principle that supplants a Boolean -algebra of intrinsic properties of a classical system by a -complex (a union of -algebras) of extrinsic properties of a quantum system that are elicited by interactions with other systems.

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...
