Discrete chiral symmetry and mass shift in the lattice Hamiltonian approach to the Schwinger model
We revisit the lattice formulation of the Schwinger model using the Kogut-Susskind Hamiltonian approach with staggered fermions. This model, introduced by Banks et al. Phys. Rev. D 13, 1043 (1976)10.1103/PhysRevD.13.1043, contains the mass term m_{lat}∑_{n}(−1)^{n}χ_{n}^{†}χ_{n}, and setting it to z...
