Open Source MPS (OSMPS) is a collection of numerical routines for performing tensor network algorithms to simulate entangled, 1D many-body quantum systems. Our applications reach from ground state and excited states for statics to the dynamics of time-dependent Hamiltonians. We offer various time evolution methods with an emphasis on the support of long-range interactions through the matrix product state formalism.

This programme addresses the notoriously difficult problem to quantitatively link measured Raman depolarization values to theoretical polarizability tensor quantities, since quantum calculations do not incorporate experimental parameters. A numerical model is programme to calculate, for realistic experimental configurations, effective Raman line strength functions, which find their way into depolarization ratios. The model is based on interlinked integrations over the angles in the light collection path, and a finite Raman source volume along the excitation laser beam. ...
