We use kinetic Monte Carlo simulations to produce solutions of an agent-based, rate equation model of an informationally efficient, closed financial market. The simulations produce a crash in the market that is forewarned through the observation of a

The need to integrate computation into the physics curriculum has long been established: using simulations and computational modeling can enhance students’ conceptual understanding, and the computational skills students acquire are both useful and

We build on the developments in the application of statistical mechanics, notably the identity of the spin degree of freedom in the Ising model, to explain asset price dynamics in financial markets with a representative agent. Specifically, we consid

We discuss the high temperature decay of isolated hills and saddle points on Si(001). Using in situ dark-field imaging in low energy electron microscopy, we track the movement of individual steps during high temperature annealing. We find different t

We have studied the morphology of pentacene films on different silicon surfaces with orientations between Si(1 1 1) and Si(0 0 1). Pentacene molecules are immobile on the Si surface, covering and passivating reactive defect sites. Molecules deposited

We studied the self-assembly of wire-shaped Ag islands at high temperature with low energy electron microscopy and photoemission electron microscopy. A Au-faceted vicinal Si(0 0 1) surface was used as a substrate. The initial Ag deposit at 600–620

We have studied the effects of controlled ion bombardment on the electronic structure of the Si(0 0 1) surface. The surface was exposed to various doses of Ar + ions accelerated towards the surface at 500 eV. X-ray photoelectron spectroscopy (XPS) sp

The well known dimer-dangling-bond surface state of the Si(001)2×1 surface is very sensitive to even a small amount of adsorption from the ambient pressure in an UHV chamber. The authors show the decay of the surface state intensity, obtained with u
