Ginzburg-Landau approach to the vortex--domain wall interaction in superconductors with nematic order

|
By Departamento de Física, P. D. Mininni, R. S. Severino, E. Fradkin
| Physical Review B
In this work, we study the interaction between vortices and nematic domain walls within the framework of a Ginzburg-Landau approach. The free energy of the system is written in terms of a complex order parameter characteristic of s-wave superconductivity and a real (Ising-type) order parameter associated with nematicity. The interaction between both order parameters is described by a biquadratic and a trilinear derivative term.

Effect of electromagnetic boundary conditions on the onset of small-scale dynamos driven by convection

|
By M. Fontana, Departamento de Física, Ciudad Universitaria, P. D. Mininni
| Physical Review B
Abstract We present a high-order numerical study of the dependence of the dynamo onset on electromagnetic boundary conditions in convecting Boussinesq flows forced by temperature gradients. Perfectly conducting boundaries, vacuum, and mixed boundary conditions are considered, treating fields and boundary conditions with close to spectral accuracy. Having one or two conducting boundaries greatly facilitates dynamo action.
