Possible generation of -ray laser by electrons wiggling in a background laser
Qi-Ren Zhang
The possibility of ray laser generation by the radiation of wiggling electrons in an usual background laser is discussed.
Quantum electrodynamics in a laser and the electron laser collision
Qi-Ren Zhang
Quantum electrodynamics in a laser is formulated, in which the electron-laser interaction is exactly considered, while the interaction of an electron and a single photon is conside…
A General Information Theoretical Proof for the Second Law of Thermodynamics
Qi-Ren Zhang
We show that the conservation and the non-additivity of the information, together with the additivity of the entropy make the entropy increase in an isolated system. The collapse o…
Some Non-Perturbative and Non-Linear Effects in Laser-Atom Interaction
Qi-Ren Zhang
We show that if the laser is intense enough, it may always ionize an atom or induce transitions between discrete energy levels of the atom, no matter what is its frequency. It mean…
Statistical Separability and the Consistency between Quantum Theory, Relativity and the Causality
Qi-Ren Zhang
We show that the non-locality together with the statistical character makes the world statistically separable. The super-luminal signal transmission is impossible. The quantum theo…
Collapse of the Entangled State and the Entropy Increase in an Isolated System
Qi-Ren Zhang
We show that the collapse of the entangled quantum state makes the entropy increase in an isolated system. The second law of thermodynamics is thus proven in its most general form.
