Description

We present a generalization of the dynamics used in HMC that allows for an arbitrary range of auxiliary field content along with freedom in choosing the dynamics (including non-symplectic dynamics), constrained mainly by the Metropolis-Hastings acceptance requirement. We will discuss how the generalized dynamics relates to other HMC variations that have appeared in the literature. We will also explore one variation related to heatbath sampling and present numerical results from 1d XY and 2d U(1) pure gauge theories. Lastly we will mention a few other variations for exploration among the large range of possibilities.
