Higher-Order Methods for Quantum Simulations
A. T. Sornborger, E. D. Stewart
To efficiently implement many-particle quantum simulations on quantum computers we develop and present methods for inverting the Campbell-Baker-Hausdorff lemma to 3rd and 4th order…

A General Supergravity Formalism for a Naturally Flat Inflaton Potential
Ewan D. Stewart
A globally supersymmetric model of inflation will not work in a generic supergravity theory because the higher order, nonrenormalisable supergravity corrections destroy the flatnes…
