Last day. Blogging will be feeble.
Force from non-equilibrium fluctuations, M. Kardar. Fluctuation force: pressure of particles against the walls. As the temperature goes to zero the length scale becomes larger than the distance between the walls and one obtains Casimir forces [see “The theory of molecular attractive forces between solids”] Quantum effect. In classical systems you can get this kind of interactions if you have long-range correlations: the Goldstone mode, and when you have a nonequilibrium system. Rytov: fluctuational QED. Kardar considers an analogue of Rytov’s theory based on fluctuating hydrodynamics which is hydrodynamics with noise.
Final session. This was actually quite an interesting section. Lecomte’s talk on finite-time corrections to large deviations and dynamical phase transitions, an interesting talk on coalescent random walk (that is analytically solvable). Hartmann proposed a method to calculate work statistics using a computational trick based on generating a whole series of random numbers first, and then accepting events based on a modified “tilted” Metropolis rule, something that might provide an alternative to other algorithms like cloning. A nice large-deviation approach that they applied to an Ising model with 128^2 spins (quite a lot already). He also launched www.papercore.org.
