Because the two components are polarized in different directions, they are added constructively or destructively depending on the positions of the observer relative ...

7.2 Angular Momentum
... When no net external torque acts on a closed system, the total angular momentum of the system does not change. Skaters, gymnasts, dancers, and divers use conservation of angular momentum. For example, a diver changes from a pike position to an extended position at the end of a flip. This extension o ...

A full set of dynamical equations were then constructed from Heisenberg’s equation of motion, and were used to model the excitonic correlations as a function of time. Transmittance and absorbance were calculated for different nanorod orientations and electric field s ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
