Thermal equilibrium and statistical thermometers in special relativity
(American Physical Society, 2007)
There is an intense debate in the recent literature about the correct generalization of Maxwell’s velocity distribution in special relativity. The most frequently discussed candidate distributions include the Jüttner ...

Solitary wave billiards
(American Physical Society, 2023-03)
In the present work we explore the concept of solitary wave billiards. That is, instead of a point particle, we examine a solitary wave in an enclosed region and examine its collision with the boundaries and the resulting ...

Quasidiscrete microwave solitons in a split-ring-resonator-based left-handed coplanar waveguide
(2011)
We study the propagation of quasidiscrete microwave solitons in a nonlinear left-handed coplanar waveguide coupled with split-ring resonators. By considering the relevant transmission line analog, we derive a nonlinear ...

Morphotropic Phase Boundary in Solution-Derived (Bi0.5Na0.5)1 – xBaxTiO3 Thin Films: Part I Crystalline Structure and Compositional Depth Profile
(The American Ceramic Society, 2014-04)
In this work, ferroelectric (Bi0.5Na0.5)1 – xBaxTiO3 thin films were fabricated by chemical solution deposition (CSD) with compositions x = 0.050–0.150. Stoichiometric thin films (here-inafter BNBT) and others containing ...

Self-diffusion in freely evolving granular gases
(American Institute of Physics, 1994)
A self-diffusionequation for a freely evolving gas of inelastic hard disks or spheres is derived starting from the Boltzmann–Lorentz equation, by means of a Chapman–Enskog expansion in the density gradient of the tagged ...

Environmental modelling in the Gulf of Cadiz: Heavy metal distributions in water and sediments
(Elsevier, 2009)
The Gulf of Cadiz (GoC) connects the Atlantic Ocean and the Mediterranean Sea. An environmental study of the GoC is carried out through numerical modelling. First, a 3D baroclinic model is used to obtain the residual circulation ...

Discrete breathers in a forced-damped array of coupled pendula: modeling, computation, and experiment
(2009)
In this work, we present a mechanical example of an experimental realization of a stability reversal between on-site and intersite centered localized modes. A corresponding realization of a vanishing of the Peierls-Nabarro ...

Moving breathers in bent DNA with realistic parameters
(2004-10-30)
Recent papers have considered moving breathers (MBs) in DNA models including long range interaction due to the dipole moments of the hydrogen bonds. We have recalculated the value of the charge transfer when hydrogen ...

Nonlinear waves in a chain of magnetically coupled pendula
(Acoustical Society of America, 2018)
A motivation for the study of reduced models like one-dimensional systems in Solid State Physics is the complexity of the full problem. In recent years our group has studied theoretically, numerically and experimentally ...
