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 ...

Type II entanglement in classical mechanics

open access: yesResults in Physics, 2021
A classical analog of entanglement using classical light beams was proposed recently. It was shown that this analog is valid only for single-particle entanglement (type II).

Disorder-induced quantum-to-classical transition, or how the world becomes classical [PDF]

open access: yesEPJ Web of Conferences, 2022
Decoherence theory explains how quantum mechanics gives rise to classical mechanics through the entanglement of a quantum system’s evolution with the degrees of freedom of the environment.

Quantum–Classical Mechanics and the Franck–Condon Principle

open access: yesComputer Sciences & Mathematics Forum, 2023
Quantum–classical mechanics and the Franck–Condon principle related to quantum mechanics are discussed as two alternative theoretical approaches to molecular optical spectroscopy.

Elementary Solution of Kepler Problem (and a few other problems)

open access: yesRevista Brasileira de Ensino de Física, 2022
We present a simple method to obtain the solution of a few orbital problems: the Kepler problem, the modified Kepler problem by the addition of an inverse square potential and linear force.

Transmutation of central forces and Bertrand’s theorem [PDF]

open access: yesTheoretical and Applied Mechanics, 2023
The transmutation of central forces, or dual law, is a transformation linking potentials in power law relative to the distance, that is, those having a positive exponent to those having a negative exponent.

The functional mechanics: evolution of the moments of distribution function and the poincare recurrence theorem

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
One of modern approaches to a problem of the coordination of classical mechanics and the statistical physics - the functional mechanics is considered.

Probabilistic cellular automata for interacting fermionic quantum field theories

open access: yesNuclear Physics B, 2021
A classical local cellular automaton can describe an interacting quantum field theory for fermions. We construct a simple classical automaton for a particular version of the Thirring model with imaginary coupling. This interacting fermionic quantum field

Classical analogue to driven quantum bits based on macroscopic pendula

open access: yesScientific Reports, 2023
Quantum mechanics increasingly penetrates modern technologies but, due to its non-deterministic nature seemingly contradicting our classical everyday world, our comprehension often stays elusive.

Assessing learning outcomes in middle-division classical mechanics: The Colorado Classical Mechanics and Math Methods Instrument

open access: yesPhysical Review Physics Education Research, 2017
Reliable and validated assessments of introductory physics have been instrumental in driving curricular and pedagogical reforms that lead to improved student learning. As part of an effort to systematically improve our sophomore-level classical mechanics
