A quantum Monte-Carlo method for fermions, free of discretization errors
S. Rombouts, K. Heyde, N. Jachowicz
In this work we present a novel quantum Monte-Carlo method for fermions, based on an exact decomposition of the Boltzmann operator . It can be seen as a synthesis of seve…

A discrete Hubbard-Stratonovich decomposition for general, fermionic two-body interactions
S. Rombouts, K. Heyde, N. Jachowicz
A scheme is presented to decompose the exponential of a two-body operator in a discrete sum over exponentials of one-body operators. This discrete decomposition can be used instead…
