# Dynamical windows for real-time evolution with matrix product states

@article{Phien2013DynamicalWF, title={Dynamical windows for real-time evolution with matrix product states}, author={Ho N. Phien and Guifr{\'e} Vidal and I. P. McCulloch}, journal={Physical Review B}, year={2013}, volume={88}, pages={035103} }

We propose the use of a dynamical window to investigate the real-time evolution of quantum many-body systems in a one-dimensional lattice. In a recent paper [Phien et al., Phys. Rev. B 86, 245107 (2012)], we introduced infinite boundary conditions in order to investigate real-time evolution of an infinite system under a local perturbation. This was accomplished by restricting the update of the tensors in the matrix product state to a finite region known as a window, with left and right…

### Fast convergence of imaginary time evolution tensor network algorithms by recycling the environment

- Computer Science
- 2015

An environment recycling scheme to speed up a class of tensor network algorithms that produce an approximation to the ground state of a local Hamiltonian by simulating an evolution in imaginary time, which confirms that a consistent choice of gauge in the bond indices confirms that the environment is essentially the same over many time steps and can thus be re-used, leading to very substantial computational savings.
