Thermopower of orbital Kondo effect in quantum dot systems

We study the thermopower of the orbital Kondo effect in single quantum dot systems by exploiting the Bethe ansatz solution of the Anderson impurity model. It is shown that the low-temperature thermopower has a negative value, and is enhanced in the Kondo regime. The difference between the spin and o...

Zusammenfassung:	We study the thermopower of the orbital Kondo effect in single quantum dot systems by exploiting the Bethe ansatz solution of the Anderson impurity model. It is shown that the low-temperature thermopower has a negative value, and is enhanced in the Kondo regime. The difference between the spin and orbital Kondo effects is discussed.
