摘要:
The concept of particles of light is introduced by ascribing a mechanical degree of freedom to a radiational wave packet. Evolution of the position and momentum observables of such particle in a dispersive dielectric is studied. It is shown that an initial coherent state evolves into a dispersed state which is characterized by a reduction of quantum fluctuations below Standard Quantum Limit when a certain combination of the position and momentum observables is measured.
