In the Ginzburg-Landau model for superconductivity a large Ginzburg-Landau parameter κ corresponds to the formation of tight, stable vortices. These vortices are located where an applied magnetic field pierces the superconducting bulk, and each vortex induces a quantized supercurrent about the vortex. The energy of large-κ solutions blows up near each vortex which brings about difficulties in a...

En 2019 Carlos Ginzburg donó un conjunto de documentos su archivo personal al Archivo Arte del Centro la Universidad Nacional La Plata (UNLP), a partir colaboración investigador Fernando Davis y Red Conceptualismos Sur. Se trata alrededor 142 fotografías, negativos fotográficos, volantes recortes prensa acompañados, en muchos casos, por anotaciones artista, que conforman cuerpo materiales sobre...

– We investigate the phase behaviour of random copolymers melts via large scale Monte Carlo simulations. We observe macrophase separation into A and B–rich phases as predicted by mean field theory only for systems with a very large correlation λ of blocks along the polymer chains, far away from the Lifshitz point. For smaller values of λ, we find that a locally segregated, disordered microemuls...
