Excitations and the tangent space of projected entangled-pair states
Laurens Vanderstraeten, Michaël Mariën, Frank Verstraete +1
We develop tangent space methods for projected entangled-pair states (PEPS) that provide direct access to the low-energy sector of strongly-correlated two-dimensional quantum syste…

Scattering particles in quantum spin chains
Laurens Vanderstraeten, Frank Verstraete, Jutho Haegeman
A variational approach for constructing an effective particle description of the low-energy physics of one-dimensional quantum spin chains is presented. Based on the matrix product…
