Hidden Caldeira-Leggett dissipation in a Bose-Fermi Kondo model
Mei-Rong Li, Karyn Le Hur, Walter Hofstetter
We show that the Bose-Fermi Kondo model (BFKM), which may find applicability both to certain dissipative mesoscopic qubit devices and to heavy fermion systems described by the Kond…
Unification of electromagnetic noise and Luttinger liquid via a quantum dot
Karyn Le Hur, Mei-Rong Li
We investigate the effect of dissipation on a small quantum dot (resonant level) tunnel-coupled to a chiral Luttinger liquid (LL) with the LL parameter . The dissipation stems f…
Dynamical Conductivity of Disordered Quantum Hall Stripes
Mei-Rong Li, H. A. Fertig, R. Cote +1
We present a detailed theory for finite-frequency conductivities Re of quantum Hall stripes, which form at Landau level close to half filling, in the presenc…
Double-dot charge qubit and transport via dissipative cotunneling
Mei-Rong Li, Karyn Le Hur
We investigate transport through an exotic ``charge'' qubit composed of two strongly capacitively coupled quantum dots (QDs), each being independently connected to a side gate whic…
