نویسنده
چکیده
We demonstrate that a fluidized bed of hard spheres undergoes a glass transition during defluidization. As in other glass-forming systems, the dynamics of the bed becomes heterogeneous as the transition is approached; spatial and temporal correlation scales increase rapidly. Microscopic motion persists in the glass state, but the bed can be jammed (all motion arrested) by application of a small increase in flow rate. Thus a fluidized bed can serve as a test system for studies of the glass transition and jamming in hard sphere systems.

We have studied the 3-flavor, finite temperature, QCD phase transition with staggred fermions on an Nt = 4 lattice. By studying a variety of quark masses we have located the critical point, mc, where the first order 3-flavor transition ends as lying in the region 0.32 ≤ mc ≤ 0.35 in lattice units.

We consider the logistic map over quaternions H ∼ R 4 and different 2D projections of Mandelbrot set in 4D quaternionic space. The approximations (for finite number of iterations) of these 2D projections are fractal circles. We show that a point process defined by radiuses Rj of those fractal circles exhibits pure 1/f noise.

Although predicted theoretically excitonic phase transitions have never been observed. Recently it has been claimed that they can occur in some strongly correlated materials. We study the possibility of an excitonic transition in a two-band model and show that a true phase transition never occurs in the presence of hybridization. We suggest an

Under an appropriate change of the perturbation variable LifshitzKhalatnikov propagation equations for the scalar perturbation reduce to d’Alembert equation. The change of variables is based on the Darboux transform.
