Persistent current noise
Andrew G. Semenov, Andrei D. Zaikin
We demonstrate that persistent current in meso- and nanorings may fluctuate down to zero temperature provided the current operator does not commute with the total Hamiltonian of th…

Persistent currents in nanorings and quantum decoherence by Coulomb interaction
Andrew G. Semenov, Andrei D. Zaikin
Employing instanton technique we evaluate equilibrium persistent current (PC) produced by a quantum particle moving in a periodic potential on a ring and interacting with a dissipa…

Aharonov-Bohm oscillations in coupled quantum dots: Effect of electron-electron interactions
Andrew G. Semenov, Dmitri S. Golubev, Andrei D. Zaikin
We theoretically analyze the effect of electron-electron interactions on Aharonov-Bohm (AB) current oscillations in ring-shaped systems with metallic quantum dots pierced by extern…
