A Runge–Kutta method takes small time steps, to approximate the solution to an initial value problem. How accurate is this approximation? If the error is asymptotically proportional to hp, where h is the stepsize, the Runge–Kutta method is said to have “order” p. To find p, write the exact solution, after a single time-step, as a Taylor series, and compare with the Taylor series for the approxi...

s − Invited Talks Eric Clément, Philippe Claudin, Bruno Andreotti PMMH-ESPCI , 10 rue Vauquelin, 75005, Paris. "Creep, fluidity and non-local microscopic processes in granular rheology" Granular materials belong to the class of amorphous athermal systems. Like foams, emulsions, suspensions, or metallic glasses, they exhibit a dynamical phase transition between static and flowing states. Analogo...

Money MesMeRizes a nd MysTifies. Its influence extends far beyond the steely confines of numbers, ledgers, and rational calculations. Yet, for a long time economists managed to keep monetary analysis safely constrained within technical territory. Coinciding with Gertrude Stein’s (1936: 88) sober dictum that “whether you like it or whether you do not, money is money and that is all there is abou...

s of Invited Talks Ian Affleck UBC, Vancouver Phase Diagram of a Chain of Interacting Majorana Fermions While the interacting Dirac fermion chain is well understood, the chain of Majorana (Hermitean) fermion operators has recently been proposed as an experimentally realizable model. I will discuss its fascinating phase diagram which includes the supersymmetric tri-critical Ising point and a gen...

One of the most challenging questions of today, in the overlap of computer science, mathematics, and physics, is the exploration of potential capabilities of quantum computers. Milestones which intensified and enlarged research considerably were the algorithm of Shor [1], who showed that quantum computers could factor large integers efficiently (which is widely believed to be infeasible on clas...
