A nice tutorial on modern gradient-based MCMC samplers highlighting the link between continuous time theoretical analysis and issues that matter to practitioners. This would have been ideal background for understanding modern developments in MCMC I saw at math.ethz.ch/fim/activiti...

From Continuous Dynamics to Practical Gradient-Based Samplers

Gradient-based Markov chain Monte Carlo methods are often introduced as a catalog of algorithms: Hamiltonian Monte Carlo (HMC), the Metropolis-adjusted Langevin algorithm (MALA), the No-U-Turn Sampler...
