受引力与晶体中缺陷的对偶性的启发，我们研究了有挠格点场论。扭转是通过晶格的线缺陷，即位错来实现的。对于第一个应用程序，我们进行了数值计算的矢量和轴向电流引起的螺旋位错。这种电流产生被称为手征扭转效应。我们还推导了连续极限下手征扭转效应的解析公式。
Inspired by the duality between gravity and defects in crystals, we study lattice field theory with torsion. The torsion is realized by a line defect of a lattice, namely, a dislocation. For the first application, we perform the numerical computation for vector and axial currents induced by a screw dislocation. This current generation is called the chiral torsional effect. We also derive the analytical formula for the chiral torsional effect in the continuum limit.
