| Outline of Final Research Achievements |
Properties of quark-gluon matter under extreme environments have been studied, especially when magnetic fields and gravity effects are strong. Then, new mechanisms for chiral symmetry breaking have been found. In a strong magnetic field a possibility of neutral scalar mesons coupling to the magnetic field through quark polarization has been pointed out, and a significant enhancement of scalar fluctuations induced by the magnetic field has been demonstrated. In a strongly curved space, it has been found that the curvature gives a fermion mass gap in a way not to break chiral symmetry, which has been named the chiral gap effect. Also, by using the real-time simulation, the particle production problem under a strong electric field has been analyzed, and a new method has been proposed based on the stochastic quantization.
