Generalized Transition Waves and Their Properties [PDF]
Communications on Pure and Applied Mathematics, 2012 AbstractIn this paper, we generalize the usual notions of waves, fronts, and propagation speeds in a very general setting. These new notions, which cover all usual situations, involve uniform limits, with respect to the geodesic distance, to a family of hypersurfaces that are parametrized by time.

Direct observation of a "devil's staircase'' in wave-particle interaction [PDF]
, 2006 We report the experimental observation of a "devil's staircase'' in a time dependent system considered as a paradigm for the transition to large scale chaos in the universality class of hamiltonian systems. A test electron beam is used to observe its non-

Description of 8Be as Deformed Gas-like Two-Alpha-Paricle States [PDF]
, 2002 In order to study non-zero spin excitations of the recently proposed alpha-cluster condensation in the self-conjugate 4n nuclei, spatial deformation is introduced into the model wave function of the alpha-cluster condensate. The rotational band states of

The Generation of Long Waves in the Laboratory
Coastal Engineering 1980, 1980 It became evident in the experimental aspects of a recent study of the propagation of nonlinear long waves past a step and up a slope that it was important to be able to generate waves which were initially well defined. The investigation dealt with the reflection and transmission of tsunamis past the continental shelf-break, and as such, two simple ...
