Rapid Mixing
In the past decade many proofs of tractability have involved showing that some Markov chain ”mixes rapidly”. We will do a fast tour of the highlights of Markov chain mixing, with a view toward answering—or at least addressing—the following questions: What is rapid mixing? How do you prove it, and why would you want to? Does it really have anything to do with computational complexity? And, most ...

متن کاملMixing Quantum and Classical Mechanics
Using a group theoretical approach we derive an equation of motion for a mixed quantum-classical system. The quantum-classical bracket entering the equation preserves the Lie algebra structure of quantum and classical mechanics: The bracket is antisymmetric and satisfies the Jacobi identity, and, therefore, leads to a natural description of interaction between quantum and classical degrees of f...
متن کاملFLUID MECHANICS AND TRANSPORT PHENOMENA Characterization of Flow and Mixing in an SMX Static Mixer
Laminar flow and mixing of a Newtonian fluid are characterized in a four-element Koch-Glitsch SMX static mixer. The computational analysis on a fine, unstructured mesh containing more than 3.5 million tetrahedral elements led to high-resolution numerical data for ®elocity and pressure. Computed pressure drops agreed excellently with those in the literature. The flow in this static mixer is esse...
متن کاملA Theory of Fluid Mixing
A recently developed theory of uid mixing is summarized here. It describes linear advection of a passive scalar by a random velocity eld. Asymptotic scaling laws are given, which are consistently derived from leading order results of primitive and renormalized perturbation theory in both the Eulerian and Lagrangian pictures. The theory has been veri ed by numerical simulation, for moderately la...
