标题： Lattice field theory with torsion

摘要： 受引力与晶体缺陷之间对偶关系的启发，我们研究了具有挠率的晶格场论。 挠率由晶格中的线缺陷（即位错）来实现。 作为第一个应用，我们针对由螺型位错诱导的矢量和轴向电流进行了数值计算。 这种电流生成被称为手性挠性效应。 我们还推导了连续极限下手性挠性效应的解析公式。 显示英文摘要

摘要： 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. As 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.
