Methods

OrthogonalNpcLinearOperator.__init__(...)
OrthogonalNpcLinearOperator.adjoint()	Return the hermitian conjugate of self.
OrthogonalNpcLinearOperator.matvec(vec)
OrthogonalNpcLinearOperator.to_matrix()	Contract self to a matrix.
OrthogonalNpcLinearOperator.unwrapped()	Return to the original NpcLinearOperator.

class tenpy.linalg.sparse.OrthogonalNpcLinearOperator(orig_operator, ortho_vecs)

Bases: NpcLinearOperatorWrapper

Replace H -> P H P with the projector P = 1 - sum_o |o> <o|.

Here, |o> are the vectors from ortho_vecs.

Parameters:

• orig_operator (EffectiveH) – The original EffectiveH instance to wrap around.

• ortho_vecs (list of Array) – The vectors to orthogonalize against.

to_matrix()

Contract self to a matrix.

adjoint()

Return the hermitian conjugate of self.

If self is hermitian, subclasses can choose to implement this to define the adjoint operator of self.

unwrapped()

Return to the original NpcLinearOperator.

If multiple levels of wrapping were used, this returns the most unwrapped one.
