... • This treatment is not just hypothetical. The vacuum energy in the E-M field depends on confinement by conductors. Therefore a force is exerted on the conductors (the Casimir force). It's measurable, rather precisely. • A force depends on differences in energy as a function of position. So measurin ...

Second Order Phase Transitions
... Second order phase transitions occur when a new state of reduced symmetry develops continuously from the disordered (high temperature) phase. The ordered phase has a lower symmetry than the Hamiltonian—the phenomenon of spontaneously broken symmetry. There will therefore be a number (sometimes infin ...

4.1. INTERACTION OF LIGHT WITH MATTER
... The Hamiltonian for the matter H M is generally (although not necessarily) time independent, whereas the electromagnetic field H L and its interaction with the matter H LM are time-dependent. A quantum mechanical treatment of the light would describe the light in terms of photons for different modes ...
