build_global_T()

MPS::Operator syten::MPS::TEBD::build_global_T	(	MPS::Lattice const &	lat,
		MPS::Operator const &	bond_operator,
		SDef	dt,
		BondOperatorType const	type
	)

builds one MPO for time evolution

Parameters

[in]	lat	the lattice to act on
[in]	bond_operator	the Hamiltonian of all either even or odd bonds \( \sum_{\text{even/odd}} \widehat{h}_i \)
[in]	dt	prefactor of the local bond operator when calculating matrix exponential, this is the timestep for first order, for higher order it is the timestep with a prefactor
[in]	type	parity of local bonds

Returns

the time evolution MPO
