seemps.operators.MPOList#

class seemps.operators.MPOList(mpos, strategy=<seemps.state.core.Strategy object>)[source]#

Sequence of matrix-product operators.

This implements a list of MPOs that are applied sequentially. It can impose its own truncation or simplification strategy on top of the one provided by the individual operators.

Parameters:

mposlist[MPO]: Operators in this sequence, to be applied from mpos[0] to mpos[-1]. Must contain at least one operator.
strategyStrategy, optional: Truncation and simplification strategy, defaults to DEFAULT_STRATEGY

Attributes

mpos	(list[MPO]) Operators in this sequence, to be applied from mpos[0] to mpos[-1]. Must contain at least one operator.
strategy	(Strategy) Truncation and simplification strategy.
size	(int) Number of quantum subsystems in each MPO. Computed from the supplied MPOs. Not checked for consistency.
