abstract = {<p style="text-align: justify;">We study a novel class of numerical integrators, the adapted nested force-gradient
schemes, used within the molecular dynamics step of the Hybrid Monte Carlo
(HMC) algorithm. We test these methods in the Schwinger model on the lattice, a well
known benchmark problem. We derive the analytical basis of nested force-gradient
type methods and demonstrate the advantage of the proposed approach, namely reduced
computational costs compared with other numerical integration schemes in
HMC.&nbsp;</p>},
