Tunneling in multi-site mesoscopic quantum Hall circuits
D. B. Karki
Transport properties of single- and two-site mesoscopic quantum Hall (QH) circuits at high transparencies can be described in terms of the lowest-order backscattering processes, en…

Multi-mode Coulomb blockade oscillations
D. B. Karki
We develop a theory of Coulomb blockade oscillations in transport and thermodynamic properties of a mesoscopic device having multiple charging energy modes. This setup can be reali…

Quantum criticality in coupled hybrid metal-semiconductor islands
D. B. Karki
We show that the combined effects of dynamical Coulomb blockade and integer quantum Hall effect in a coupled hybrid metal-semiconductor setup provide a pathway for realizing resona…
