Mixing Time Lower Bounds for Standard Strang Splittings of Kinetic Langevin Dynamics
Paper: arXiv:2608.25279. The previous post on this blog ended with an open problem. With Sonja Cox and Roy Schieven we had proved a sharp Wasserstein-to-total-variation regularization estimate for the OBABO … Read More
On Couplings for Kinetic Langevin Diffusions
Joint work with Sonja Cox and Roy Schieven (University of Amsterdam). Paper: arXiv:2605.31088 · Lecture Slides (PDF). Two copies of the same diffusion, started apart. How can you get them … Read More
New paper: Neural Quantum States in Mixed Precision
This work grew out of a particularly synergistic interdisciplinary collaboration with Massimo Solinas, Agnes Valenti, and Roeland Wiersema at the Center for Computational Quantum Physics, Flatiron Institute. A basic, but … Read More
