Quantum physics direct detection

In the quantum field theories that describe the physics of elementary particles, the vacuum becomes somewhat more complex than previously defined. Even in empty space, matter can appear spontaneously as a result of fluctuations of Ihe vacuum. It may be pointed, out, for example, that an electron and a positron, or antielectron, can be created out of the void, Particles created in this way have only a fleeting existence they are annihilated almost as soon as they appear, and their pressure can never be detected directly. They are called virtual particles in order to distinguish them from real particles. Thus, the traditional definition of vacuum (space with no real particles in it) holds. In their excellent paper, the aforementioned authors discuss how, near a superheavy atomic nucleus, empty space may become unstable, with the result that matter and antimatter can be created without any input of energy. The process may soon be observed experimentally. [Pg.1661]

Quantum-mechanical phase measurement for I-frame quantum systems provides a most direct manifestation of underlying abstract physics. Physical quantum states as projected states are to be probed at a laboratory level. Registering a resulting physical quantum state generates events with implied energy conservation rules. It can also be accomplished by further interactions leading to a detectable physical process. This is the crux of the problem. [Pg.51]
