Theory of the Kondo Temperature in Multilevel Quantum Dots

ORAL

Abstract

We develop a simple but general method to evaluate the Kondo temperature in a multilevel quantum dot that is weakly coupled to conducting leads. Our analysis reveals that the Kondo temperature is strongly enhanced when the intradot energy-level spacing is smaller than the charging energy.
