Considerations on the Relativity of Quantum Irrealism

Entropy, 2023
The study of quantum resources in the relativistic limit has attracted attention over the last couple of decades, mostly due to the observation that the spin-momentum entanglement is not Lorentz covariant.

Time in Quantum Mechanics and the Local Non-Conservation of the Probability Current

Mathematics, 2018
In relativistic quantum field theory with local interactions, charge is locally conserved. This implies local conservation of probability for the Dirac and Klein–Gordon wavefunctions, as special cases; and in turn for non-relativistic quantum field

Geometry, stochastic calculus and quantum fields in a non-commutative space-time

, 1999
The algebras of non-relativistic and of classical mechanics are unstable algebraic structures. Their deformation towards stable structures leads, respectively, to relativity and to quantum mechanics.

Persistent Mono‐Oxo Bonding with Protactinium(V) Revealed in Highly Acidic Chloride Solutions

Angewandte Chemie, EarlyView.
Protactinium(V) defies expectations. Its elusive mono‐oxo bond was revealed through a combination of extended X‐ray absorption fine structure (EXAFS) and X‐ray absorption near‐edge structure (XANES) analyses, as well as quantum chemical calculations. This bond persists even in 12 M HCl.

A New Space-Time Theory Unravels the Origins of Classical Mechanics for the Dirac Equation

Quantum Reports
The Feynman path integral plays a central role in quantum mechanics, linking classical action to propagators and relating quantum electrodynamics (QED) to Feynman diagrams.

Recurrence relation for relativistic atomic matrix elements

, 2000
Recurrence formulae for arbitrary hydrogenic radial matrix elements are obtained in the Dirac form of relativistic quantum mechanics. Our approach is inspired on the relativistic extension of the second hypervirial method that has been succesfully ...

Ultra‐Low‐Cost Hydrophobic Organic Coating for Highly Reversible Zinc Anodes

Angewandte Chemie, EarlyView.
A nanoscale hydrophobic 1,3‐Di(o‐tolyl)thiourea (DTH) layer (<14 nm) was deposited on zinc anodes for durable aqueous Zn‐ion batteries, costing merely 1.43×10−7 USD·Ah−1. By suppressing side reactions and dendrites, it achieved 2500‐cycle coin cells and a 143 Wh·kg−1 pouch cell (1200 cycles) with a record‐low additive cost (7.02×10−7 USD).

Unification of Relativistic and Quantum Mechanics from Elementary Cycles Theory

, 2016
In Elementary Cycles theory elementary quantum particles are consistently described as the manifestation of ultra-fast relativistic spacetime cyclic dynamics, classical in the essence.
