Dirac Equation and Fisher Information [PDF]

open access: yesEntropy
Previously, it was shown that Schrödinger’s theory can be derived from a potential flow Lagrangian provided a Fisher information term is added. This approach was later expanded to Pauli’s theory of an electron with spin, which required a Clebsch flow ...

Entropic Dynamics Approach to Relational Quantum Mechanics [PDF]

open access: yesEntropy
The general framework of Entropic Dynamics (ED) is used to construct non-relativistic models of relational Quantum Mechanics from well-known inference principles—probability, entropy and information geometry.

Statistical predictions for the dynamics of a low-speed system: Newtonian versus special-relativistic mechanics. [PDF]

open access: yesPLoS ONE, 2012
The newtonian and special-relativistic statistical predictions for the mean, standard deviation and probability density function of the position and momentum are compared for the periodically-delta-kicked particle at low speed.

Scattering Study of Fermions due to Double Dirac Delta Potential in Quaternionic Relativistic Quantum Mechanics [PDF]

open access: goldAdvances in High Energy Physics, 2018
We have studied the scattering problem of relativistic fermions from a quaternionic double Dirac delta potential. We have used Dirac equation in the presence of the scalar and vector potentials in the quaternionic formalism of relativistic quantum ...

Comparison of newtonian and special-relativistic trajectories with the general-relativistic trajectory for a low-speed weak-gravity system. [PDF]

open access: yesPLoS ONE, 2012
We show, contrary to expectation, that the trajectory predicted by general-relativistic mechanics for a low-speed weak-gravity system is not always well-approximated by the trajectories predicted by special-relativistic and newtonian mechanics for the ...

The Foundation of Classical Mechanics

open access: yesEncyclopedia, 2021
Mechanics is the science of the equilibrium and motion of bodies subject to forces. The adjective classical, hence Classical Mechanics, was added in the 20th century to distinguish it from relativistic mechanics which studies motion with speed close to ...

Nanoparticle-insertion scheme to decouple electron injection from laser evolution in laser wakefield acceleration

open access: yesScientific Reports, 2022
A localized nanoparticle insertion scheme is developed to decouple electron injection from laser evolution in laser wakefield acceleration. Here we report the experimental realization of a controllable electron injection by the nanoparticle insertion ...

Analytical Bound State Solutions of the Klein-Fock-Gordon Equation for the Sum of Hulthén and Yukawa Potential within SUSY Quantum Mechanics

open access: yesAdvances in High Energy Physics, 2021
The relativistic wave equations determine the dynamics of quantum fields in the context of quantum field theory. One of the conventional tools for dealing with the relativistic bound state problem is the Klein-Fock-Gordon equation.

Editorial for the Special Issue “Relativistic Astrophysics”

open access: yesUniverse, 2022
Relativistic Astrophysics is the branch of astrophysics that studies astronomical phenomena and celestial bodies, for which classical mechanics and Newton’s law of gravitation are inapplicable to creation of suitable models and we have to generalize ...

On the Stochastic Origin of Quantum Mechanics [PDF]

open access: yesReports in Advances of Physical Sciences, 2017
The quantum Liouville equation, which describes the phase space dynamics of a quantum system of fermions, is analyzed from stochastic point of view as a particular example of the Kramers–Moyal expansion.
