Description
Recently it has been shown that the model wave functions
describing the fractional quantum Hall (FQH) effect have an
exact representation as matrix product states (MPS). This
representation is extremely useful for numerical calculation of
FQH physics. However, a crucial piece, the implementation of
the non-local quasielectron operator has been missing. We
show how to implement the quasi-electron as an MPS for the
Laughlin state and numerically compute the Berry phases for
different excitations.
