The symmetry of time reversal has always been widely interested problem which has puzzled physicists more than hundred years. According to present understanding, electromagnetic interaction is unchanged under time reversal. The reason is that the motion equations of quantum mechanics and the interaction Hamiltonian of electromagnetic interaction are invariable under time reversal. On the other hand, as we know that the evolution processes of common macro-material systems which obey the second law of thermodynamics always violate time reversal symmetry.
Because macro-systems are composed of atoms and molecules, and atoms and molecules are composed of charged micro-particles, by the logical deductions, the evolution processes of macro-systems should also have the symmetry of time reversal. There exists a basic contradiction here, that is, the so-called irreversibility paradox. By considering the consistency of nature law, we had to ask whether or not the current theory on time reversal has some basic wrong?
In fact, it has proved that when the retarded effect of radiation fields is taken into account, the light’s high order stimulated radiation and stimulated absorption probabilities are not the same so that time reversal symmetry would be violated. Meanwhile, the third order vertex angle renormalization process of electromagnetic Interaction is also proved to violate the symmetry of time reversal.
Recently, more and more experiments reveal that the symmetry violations of time reversal exist widely in particle and quantum physics. It means that the irreversibility of macro-system originates from the irreversibility of micro-interaction processes. The current theory of time reversal seems incapable to deal with these phenomena and experiment facts. It indicates that we need a new theory of time reversal. Because CPT symmetry is considered to be hold in micro-interaction processes, symmetry violation of time reversal indicates. It also indicates that we need new theories of CPT transformation. The asymmetry of positive and anti-material in the evolution processes of the universe is related to CP violation. This is an unsolved problem in cosmology. Perhaps new theory of CPT transformation may reveal this secrete.
So this is a wide and interesting field which needs to be researched deeply. However, no special issue is schemed to collect and publish the research papers in this field in the world at present. The papers are dispersed in various journals. Therefore, this special issue may cause wide interesting.
Aims and Scope:
1. Phenomena and experiment facts of symmetry violation of time reversal in micro- interaction processes. 2. Research of new time reversal theory in micro-interaction processes. 3. CPT transformation in quantum theory of field. 4. The origin of CP violation in cosmology.
