Abstract:

We show how to construct relevant families of matrix product operators in one and higher dimensions. Those form the building blocks for the numerical simulation methods based on matrix product states and projected entangled pair states. In particular, we construct translational invariant matrix product operators suitable for time evolution, and show how such descriptions are

possible for Hamiltonians with long-range interactions. We show how those tools can be exploited for constructing new algorithms for simulating quantum spin systems.
