Quantum Dynamics and Non-Inertial Frames of Reference. III: Charged Particle in Time-Dependent Uniform Electromagnetic Field [PDF]

open access: yesProgress of Theoretical Physics, 1991
By successive applications of time-dependent rotation, translation and dilatation, it is shown that' a charged time·dependent harmonic oscillator in a uniform time-dependent electromagnetic field is equivalent to a free particle. This equivalence is employed to present a simple derivation of the Feynman kernel as well as to obtain a concrete picture of

Theoretical framework for particle dynamics in translational reference frames and application to multi-body dynamics

open access: yesAIP Advances
This article presents a systematic development of a new theoretical framework for particle dynamics in translational reference frames. Based on the symmetric new equation of particle dynamics, which effectively eliminates the dependence on the inertial ...

Physics of Non-Inertial Reference Frames, conclusions and consequences

open access: yesJournal of Physics: Conference Series
Abstract Refusal to use inertial reference frames in favor of non-inertial reference frames means significant changes in the axiomatics of both classical and quantum physics. Taking into account the influences of random small forces and fields makes the equations of classical physics, expanding, subject not only to deterministic laws ...

Effect of Intermediate Path on Post-Wrinkle Initiation of the Multi-Pass Metal Spinning Process: Analysis in the Rotating Reference Frame

open access: yesJournal of Manufacturing and Materials Processing
The metal spinning process has been observed in recent major investigations carried out using finite element analysis. One interesting idea has proposed simulating a rotating disc for the simulation of the metal spinning process to reduce computational ...

Parameter Identification Method for SINS Initial Alignment under Inertial Frame

open access: yes, 2016
The performance of a strapdown inertial navigation system (SINS) largely depends on the accuracy and rapidness of the initial alignment. The conventional alignment method with parameter identification has been already applied widely, but it needs to ...

Entrainment of an inertial reference frame by an accelerated gravitating shell

open access: yes, 2000
For the example of an accelerated shell we show that omission of the energy-momentum tensor (EMT) of the body that causes the acceleration and the tensions due to this acceleration can lead to a paradoxical result; Namely, the entrainment of an inertial frame by the accelerated shell in the direction opposite to that of the acceleration.
