Translation-invariance of two-dimensional Gibbsian systems of particles with internal degrees of freedom

The conservation of translational symmetry in two-dimensional systems with interaction is a classical subject of statistical mechanics. Here we establish such a result for Gibbsian systems of marked particles with two-body interaction, where the interesting cases of singular, hard-core and discontinuous interactions are included. In particular we thus show the conservation of translational symm...

Don’t Shed Tears over Breaks

This essay deals with ‘discontinuous phenomena’ in time-series. It is an introduction to, and a brief survey of aspects concerning the concepts of segmentation into ‘smooth’ pieces on the one hand, and the complementary notion of the identification of jumps, on the other hand. We restrict ourselves to variational approaches, both in discrete, and in continuous time. They will define ‘filters’, ...

Iterative Potts and Blake-Zisserman minimization for the recovery of functions with discontinuities from indirect measurements.

Signals with discontinuities appear in many problems in the applied sciences ranging from mechanics, electrical engineering to biology and medicine. The concrete data acquired are typically discrete, indirect and noisy measurements of some quantities describing the signal under consideration. The task is to restore the signal and, in particular, the discontinuities. In this respect, classical m...

Mean-Field Analysis of Antiferromagnetic Three-State Potts Model with Next Nearest Neighbor Interaction

The three-state Potts model with antiferromagnetic nearest-neighbor (n.n.) and ferromagnetic next-nearest-neighbor (n.n.n) interaction is investigated within a mean-field theory. We find that the phase-diagram contains two kind of ordered phases, so-called BSS phase and PSS phase, separated by a discontinuous phase transition line. Order-disorder transition is continuous for the weak n.n.n. int...

Precursor phenomena in frustrated systems.

To understand the origin of the dynamical transition, between high-temperature exponential relaxation and low-temperature nonexponential relaxation, that occurs well above the static transition in glassy systems, a frustrated spin model, with and without disorder, is considered. The model has two phase transitions, the lower being a standard spin glass transition (in the presence of disorder) o...
