在三维和四维时空中研究了具有外电场和弱引力场的Nambu-Jona-Lasinio模型。复合双费米子场的有效势的计算保持项的曲率线性，而电场效应是精确地处理通过适当的时间形式主义。一个丰富的动力学对称性破缺模式，伴随着相变，这是统治，独立的，由曲率和电场强度。
An investigation of the Nambu - Jona-Lasinio model with external constant electric and weak gravitational fields is carried out in three- and four-dimensional spacetimes. The effective potential of the composite bi-fermionic fields is calculated keeping terms linear in the curvature, while the electric field effect is treated exactly by means of the proper-time formalism. A rich dynamical symmetry breaking pattern, accompanied by phase transitions which are ruled, independently, by both the curvature and the electric field strength is found. Numerical simulations of the transitions are presented.
