We present a new adaptive numerical scheme for solving parabolic PDEs in
cartesian geometry. Applying a finite volume discretization with explicit
time integration, both of second order, we employ a fully adaptive
multiresolution scheme to represent the solution on locally refined nested
grids. The fluxes are evaluated on the adaptive grid. A...

There is increasing evidence from in vivo recordings in monkeys
trained to respond to stimuli by making left- or rightward eye
movements, that firing rates in certain groups of `visual' neurons
mimic drift-diffusion processes, rising to a (fixed) threshold prior
to movement initiation. This supplements earlier observations of
psychologists, that...

The ferromagnetic Heisenberg model is conjectured to possess the
property of Ferromagnetic Ordering of Energy Levels (FOEL): the smallest
eigenvalues in the invariant subspaces of fixed total spin, S, are
monotonically decreasing in S. I will present a proof of this conjecture
for the one-...

Motivated by several physical systems, we study a simple model of driven, two-species lattice gases. Our system consists of only two types of NON-interacting (apart from an excluded volume constraint) particles, diffusing on a periodic lattice and with biased moves in opposite directions. On a square system, increasing the overall particle density...
