Lattice field theory with torsion

Understand

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.
