Fourth-order leapfrog algorithms for numerical time evolution of classical and quantum systems

Jun Hao Hue, Ege Eren, Shao Hen Chiew +5

Chau et al. [New J. Phys. 20, 073003 (2018)] presented a new and straight-forward derivation of a fourth-order approximation '$U_7$' of the time-evolution operator and hinted at it…
