The equation is valid only if \sum \tau and \bar L are measured about the same origin. Furthermore, the expression is valid for any origin fixed in an inertia frame. 也就是说,当没有torque的时候, d\bar L/dt=0, angular momentum为常量。 Angular momentum of a system of particles The ...
VN Gribov - Anomalies, as a manifestation of the high momentum collective motion in the vacuum 被引量: 6发表: 2001年 The 4-momentum of a particle and the mass shell equation in the entirely anisotropic space-time It is shown that the source of any anomalies in the theory is the collecti...
Wave-particle dualityEnergyMomentumSelf-interference of an electronMaterial dispersionThe conserved momentum and the energy of a moving particle obey a wave equation and have the wave feature. The moving particle acts as a point source of the waves. This nature is applied to explain the self-...
actually moving in the direction of the ω vector. We want to choose the direction of ω so that this gives us information about how the object is spinning. When a wheel is spinning on an axis, there is no one direction of motion (different parts of the wheel are moving in different ...

This paper constructs the new common eigenvectors of n intermediate coordinate-momentum operators which are complete and orthonormal. The intermediate coordinate-momentum representation of a multi-particles system is proposed and applied to a generaln-mode quantum harmonic oscillators system with coordinate-...
We quantify the entanglement for a range of targets and field parameters to find the most entangled photoelectron pairs. This methodology provides a general way to use OAM to quantify and measure entanglement, well-suited to attosecond processes, and can be exploited to enhance imaging capabilities ...
In the preceding equation, everything is a function of the material coordinates Xi and t, To is the first Piola-Kirchhoff stress tensor, and no is the outward normal. Using the divergence theorem for the stress tensor term,Eq. (7.6.11) becomes (7.6.12)∫VcρoDvDtdVo=∫VcDiv TodVo+...
The equation of motion for a radiating charged particle without self-interaction term Thus, the resulting equation of motion emerges from equating the total rate of change of momentum to the external force, without the introduction of a "... L Herrera - 《Physics Letters A》 被引量: 18发表...
