The $SU(4)-SU(2)$ crossover and spin filter properties of a double quantum dot nanosystem

V. Lopes, R. A. Padilla, G. B. Martins +1

The $SU(4)-SU(2)$ crossover, driven by an external magnetic field $h$, is analyzed in a capacitively-coupled double-quantum-dot device connected to independent leads. As one contin…
