狄拉克费米子的符号问题是由行列式的半正性决定的,而马约拉纳费米子的符号问题则是由普夫朗的半正性决定的。我们引入了一个半正性的充分条件。基于半正性条件,研究了一个有效的Majorana费米子模型。我们还介绍了狄拉克费米子的应用。
While the sign problem of the Dirac fermion is conditioned by the semipositivity of a determinant, that of the Majorana fermion is conditioned by the semipositivity of a Pfaffian. We introduce one sufficient condition for the semi-positivity of a Pfaffian. Based on the semi-positivity condition, we study an effective model of the Majorana fermion. We also present the application to the Dirac fermion.
