full name: tenpy.models.tf_ising
Transverse field Ising model on a general lattice.
Prototypical example of a quantum model: the transverse field Ising model.
XXZChain, the transverse field ising chain
TFIChain is contained in the more general
the idea is more to serve as a pedagogical example for a ‘model’.
We choose the field along z to allow to conserve the parity, if desired.
