Heisenberg_1d(integer length, complex transverse_field) -> ComplexMPO​

Generate the Hamiltonian MPO for the 1D Heisenberg model with Complex values.

Parameters​

  • length: Number of sites in the chain.
  • transverse_field: Strength of the transverse field (default: 0).

Returns​

MPO representing the 1D Heisenberg Hamiltonian H=∑i(SixSi+1x+SiySi+1y+SizSi+1z)+h∑iSixH = \sum_i ( S^x_i S^x_{i+1} + S^y_i S^y_{i+1} + S^z_i S^z_{i+1}) + h \sum_i S^x_i with open boundary conditions.

Heisenberg_1d(integer length, real transverse_field) -> RealMPO​

  • transverse_field: Strength of the transverse field (default: 0).

Returns​

MPO representing the 1D Heisenberg Hamiltonian H=∑i(SixSi+1x+SiySi+1y+SizSi+1z)+h∑iSixH = \sum_i ( S^x_i S^x_{i+1} + S^y_i S^y_{i+1} + S^z_i S^z_{i+1}) + h \sum_i S^x_i with open boundary conditions.
