Implementing the sine transform of fermionic modes as a tensor network
Hannes Epple, Pascal Fries, Haye Hinrichsen
Based on the algebraic theory of signal processing, we recursively decompose the discrete sine transform of first kind (DST-I) into small orthogonal block operations. Using a diagr…

On the upper bound of classical correlations in a bipartite quantum system
Theresa Christ, Haye Hinrichsen
For a bipartite quantum system consisting of subsystems A and B it was shown by Zhang et al. (Physics Letters A 376 (2012) 3588-3592) that the amount of classical correlations, whi…
