	)

Performs an 1-site iteration, e.g. solves the effective eigenvalue problem of the 1-site effective Hamiltonian and updates therewith the A-tensors directly.

Note: Standard iteration. Best tested and suited with an expansion scheme to enlarge the bond dimension.

Definition at line 1235 of file DmrgSolver.h.

◆ iteration_two()

template<typename Symmetry , typename MpHamiltonian , typename Scalar >

void DmrgSolver< Symmetry, MpHamiltonian, Scalar >::iteration_two	(	const vector< MpHamiltonian > &	H,

		double &	time_lanczos,
		double &	time_sweep,
		double &	time_LR,
		double &	time_overhead
	)

Performs an 2-site iteration, e.g. solves the effective eigenvalue problem of the 2-site effective Hamiltonian and updates therewith the two-site wavefunction.

Note: Bond dimension gets enlarged automatically. The truncated weight is a good convergence measure here and can also be used for extrapolations.; This algorithm is quite slow for challenging problems.

Definition at line 1398 of file DmrgSolver.h.

◆ iteration_zero()

template<typename Symmetry , typename MpHamiltonian , typename Scalar >

		double &	time_lanczos,
		double &	time_sweep,
		double &	time_LR,
		double &	time_overhead
	)

Performs an 0-site iteration, e.g. solves the effective eigenvalue problem of the 0-site effective Hamiltonian and updates therewith the center-matrix C.

Warning: This iteration is not extensively tested and there is no guarantee that the sweep protocol is correct.; No subspace expansion scheme is included. -> bad convergence.
