Matrix product operator representations for the local conserved quantities of the spin- XYZ chain
Kohei Fukai, Kyoichi Yamada
We present explicit matrix product operator (MPO) representations for the local conserved quantities of the spin- XYZ chain. Through these MPO representations, we simplify the…

Matrix product operator representations for the local conserved quantities of the Heisenberg chain
Kyoichi Yamada, Kohei Fukai
We present the explicit expressions for the matrix product operator (MPO) representation for the local conserved quantities of the Heisenberg chain. The bond dimension of the MPO g…
