Time-dependent variational principle with controlled bond expansion for matrix product states

JW Li, A Gleis, J Von Delft - Physical Review Letters, 2024 - APS
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 …
