Transmission Phase Shift of a Quantum Dot with Kondo Correlations
Ulrich Gerland, Jan von Delft, Theo Costi +1
We study the effects of Kondo correlations on the transmission phase shift of a quantum dot in an Aharonov-Bohm ring. We predict in detail how the development of a Kondo resonance…

Thermodynamics of the dissipative two-state system: a Bethe Ansatz study
T. A. Costi, G. Zarand
The thermodynamics of the dissipative two-state system is calculated exactly for all temperatures and level asymmetries for the case of Ohmic dissipation. We exploit the equivalenc…
