Tensor< 2 > syten::MPS::TDVP::Worker::normR

(

Index

where

)

Right-normalise tensor on site where and return the left-over bit \( \Psi(\textrm{where}) \to U S \Psi(\textrm{where}) \).

Parameters

where

position of state component in psi that is to be normalised

Returns

bond tensor \( R = U S \) left over from the SVD
