Persistent currents in n-fold twisted Moebius strips
E. H. Martins Ferreira, M. C. Nemes, M. D. Sampaio +1
We investigate the influence of the topology on generic features of the persistent current in n-fold twisted Moebius strips formed of quasi one--dimensional mesoscopic rings, both…

Tunneling Rate for Superparamagnetic Particles by the Instanton Method
E. H. Martins Ferreira, M. C. Nemes
We derive the tunneling rate for paramagnetic molecules in the context of a collective spin model. By means of path integral methods an analytical expression is derived. Given the…
