Abstract

Kondo tunneling reveals hidden [Formula presented] dynamical symmetries of evenly occupied quantum dots. As is exemplified for an experimentally realizable triple quantum dot in parallel geometry, the possible values [Formula presented] can be easily tuned by gate voltages. Following construction of the corresponding [Formula presented] algebras, scaling equations are derived and Kondo temperatures are calculated. The symmetry group for a magnetic field induced anisotropic Kondo tunneling is [Formula presented] or [Formula presented].
