Query: Least Action Principle for the Real-Time Density Matrix Renormalization
  Group   A kind of least action principle is introduced for the discrete time
evolution of one-dimensional quantum lattice models. Based on this principle,
we obtain an optimal condition for the matrix product states on succeeding time
slices generated by the real-time density matrix renormalization group method.
This optimization can also be applied to classical simulations of quantum
circuits. We discuss the time reversal symmetry in the fully optimized MPS.
