Efficient higher-order matrix product operators for time evolution
Maarten Van Damme, Jutho Haegeman, Ian McCulloch +1
We introduce a systematic construction of higher-order matrix product operator (MPO) approximations of the time evolution operator for generic (short and long range) one-dimensiona…
Fermionic Matrix Product States and One-Dimensional Topological Phases
Nick Bultinck, Dominic J. Williamson, Jutho Haegeman +1
We develop the formalism of fermionic matrix product states (fMPS) and show how irreducible fMPS fall in two different classes, related to the different types of simple $\mathbb{Z}…
Continuous matrix product states with periodic boundary conditions and an application to atomtronics
Damian Draxler, Jutho Haegeman, Frank Verstraete +1
We introduce a time evolution algorithm for one-dimensional quantum field theories with periodic boundary conditions. This is done by applying the Dirac-Frenkel time-dependent vari…
