Time-dependent variational principle with controlled bond expansion for matrix product states
Jheng-Wei Li, Andreas Gleis, Jan von Delft
We present a controlled bond expansion (CBE) approach to simulate quantum dynamics based on the time-dependent variational principle (TDVP) for matrix product states. Our method al…

Controlled bond expansion for DMRG ground state search at single-site costs
Andreas Gleis, Jheng-Wei Li, Jan von Delft
DMRG ground state search algorithms employing symmetries must be able to expand virtual bond spaces by adding or changing symmetry sectors if these lower the energy. Traditional si…

Projector formalism for kept and discarded spaces of matrix product states
Andreas Gleis, Jheng-Wei Li, Jan von Delft
Any matrix product state has a set of associated kept and discarded spaces, needed for the description of , and changes thereof, respectively. These induce a…
