ITensor implementation of the time dependent variational principle (TDVP) algorithm for finite MPS. It also includes a global subspace expansion algorithm to enlarge the bond dimension of the MPS for TDVP according to the paper arXiv:2005.06104 or Phys. Rev. B 102, 094315 (2020), which would be useful for reliable time evolution of two-dimensional systems and one-dimensional systems with long-range interactions.
Requires a working version of the ITensor library on your system.
See the sample/ directory for an example of how to run it.
