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…
parafermion in the double charge-Kondo model
D. B. Karki, Edouard Boulat, Winston Pouse +3
Quantum impurity models with frustrated Kondo interactions can support quantum critical points with fractionalized excitations. Recent experiments [arXiv:2108.12691] on a circuit c…
Two-sites quantum island in the quasi-ballistic regime
Deepak B. Karki, Edouard Boulat, Christophe Mora
Quantum Hall edge channels can be combined with metallic regions to fractionalize electrons and form correlated impurity models. We study a minimal device, that has been experiment…
Multistage Kondo effect in a multiterminal geometry: A modular quantum interferometer
D. B. Karki, Andrei I. Pavlov, Mikhail N. Kiselev
Quantum systems characterized by an interplay between several resonance scattering channels demonstrate very rich physics. To illustrate it we consider a multistage Kondo effect in…
