Quantum Coherence of the Ground State of a Mesoscopic Ring
Pascal Cedraschi, Markus Buttiker
We discuss the phase coherence properties of a mesoscopic normal ring coupled to an electric environment via Coulomb interactions. This system can be mapped onto the Caldeira-Legge…

Zero-point fluctuations in the ground state of a mesoscopic normal ring
Pascal Cedraschi, Markus Buttiker
We investigate the persistent current of a ring with an in-line quantum dot capacitively coupled to an external circuit. Of special interest is the magnitude of the persistent curr…

Suppression of level hybridization due to Coulomb interactions
Pascal Cedraschi, Markus Buttiker
We investigate an ensemble of systems formed by a ring enclosing a magnetic flux. The ring is coupled to a side stub via a tunneling junction and via Coulomb interaction. We genera…
