Collective coordinate descriptions of a kink in a driven-damped model
Jacek Gatlik, Tomasz Dobrowolski, Jean-Guy Caputo +1
Extending a recent effective theory formulation for the dynamics of kinks in the sine-Gordon model [1], we propose an analogous effective description of kinks. Three differe…

Numerical analysis of scattering on combinatorial graphs
Moysey Brio, Jean-Guy Caputo
We investigate numerically the scattering of waves on discrete graphs. An efficient algorithm is developed to compute the reflection and transmission (spectral) coefficients. We th…

Mathematical analysis of a flux-jump model in superconductivity
Jean-Guy Caputo, Nathan Rouxelin
Type II superconductors can trap a transient magnetic field and become "cryomagnets" that are very useful for applications. During this process, flux jumps i.e. sudden jumps of the…
