connect_local_operators()

Tensor<6> syten::MPS::TEBD::connect_local_operators	(	Tensor< 4 > const &	op1,
		Tensor< 4 > const &	op2
	)

Connects two singe site operators (rank 4 tensors) to a "double-site" operator (rank 6 tensor):

6   5
V       V             V   V
<[A]<   <[B]<   ->   1<[A]-[B]<4
V       V             V   V
2   3

Parameters

[in]	op1	first (left) tensor to be connected
[in]	op2	second (right) tensor to be connected

Returns

connected tensor
