Continuous Quantum Measurement and the Quantum to Classical Transition [PDF]
, 2002 While ultimately they are described by quantum mechanics, macroscopic mechanical systems are nevertheless observed to follow the trajectories predicted by classical mechanics.

On deformations of classical mechanics due to Planck-scale physics
, 2019 Several quantum gravity and string theory thought experiments indicate that the Heisenberg uncertainty relations get modified at the Planck scale so that a minimal length do arises.

Chaos in classical D0-brane mechanics [PDF]
Journal of High Energy Physics, 2015 We study chaos in the classical limit of the matrix quantum mechanical system describing D0-brane dynamics. We determine a precise value of the largest Lyapunov exponent, and, with less precision, calculate the entire spectrum of Lyapunov exponents.

Re`class'ification of `quant'ified classical simulated annealing [PDF]
, 2008 We discuss a classical reinterpretation of quantum-mechanics-based analysis of classical Markov chains with detailed balance, that is based on the quantum-classical correspondence. The classical reinterpretation is then used to demonstrate that it successfully reproduces a sufficient condition for cooling schedule in classical simulated annealing ...

Classical mechanics as nonlinear quantum mechanics
, 2007 All measurable predictions of classical mechanics can be reproduced from a quantum-like interpretation of a nonlinear Schrodinger equation. The key observation leading to classical physics is the fact that a wave function that satisfies a linear equation

On the Structure of Classical Mechanics
British Journal for the Philosophy of Science, 2015 The standard view is that the Lagrangian and Hamiltonian formulations of classical mechanics are theoretically equivalent. Jill North ([2009]), however, argues that they are not. In particular, she argues that the state-space of Hamiltonian mechanics has

Framework for understanding the patterns of student difficulties in quantum mechanics
Physical Review Special Topics. Physics Education Research, 2015 [This paper is part of the Focused Collection on Upper Division Physics Courses.] Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics ...

Contextuality in Classical Physics and Its Impact on the Foundations of Quantum Mechanics
Entropy, 2021 It is shown that the hallmark quantum phenomenon of contextuality is present in classical statistical mechanics (CSM). It is first shown that the occurrence of contextuality is equivalent to there being observables that can differentiate between pure and

On classical and functional approachs to mechanics
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011 In this paper the relevance of the classical trajectory of the anharmonic oscillator and the average trajectory obtained within the functional approach is considered.

Computation in Classical Mechanics
, 2007 There is a growing consensus that physics majors need to learn computational skills, but many departments are still devoid of computation in their physics curriculum.
