Project description
 

The ground state of one-dimensional quantum systems is succesfully described by (continuous) matrix product states. On top of this variational vacuum, elementary excitations can be created, so that we have access to the low-lying excitation spectrum with few computational costs. In this project we want to extend this framework to capture the scattering of elementary excitations, create multi-particle excitations and compute spectral functions.
