Interplay of Coulomb blockade and Aharonov-Bohm resonances in a Luttinger liquid
نویسندگان
چکیده
We consider a ring of strongly interacting electrons connected to two external leads by tunnel junctions. By studying the positions of conductance resonances as a function of gate voltage and magnetic flux the interaction parameter g can be determined experimentally. For a finite ring the minimum conductance is strongly influenced by device geometry and electron-electron interactions. In particular, if the tunnel junctions are close to one another the interaction-related orthogonality catastrophe is suppressed and the valley current is unexpectedly large. Typeset using REVTEX

Interplay of Coulomb Blockade and Aharonov-bohm Resonances in a Luttinger Liquid Typeset Using Revt E X
We consider a ring of strongly interacting electrons connected to two external leads by tunnel junctions. By studying the positions of conductance resonances as a function of gate voltage and magnetic ux the interaction parameter g can be determined experimentally. For a nite ring the minimum conductance is strongly innuenced by device geometry and electron-electron interactions. In particular,...
متن کاملCrossing of two Coulomb–Blockade Resonances
We investigate theoretically the transport of non–interacting electrons through an Aharanov–Bohm (AB) interferometer with two quantum dots (QD) embedded into its arms. In the Coulomb–blockade regime, transport through each QD proceeds via a single resonance. The resonances are coupled through the arms of the AB device but may also be coupled directly. In the framework of the Landauer–Büttiker a...
متن کاملCoulomb blockade of tunnelling through compressible rings formed around an antidot: an explanation for h/2e Aharonov-Bohm oscillations
We consider single-electron tunnelling through antidot states using a Coulomb-blockade model, and give an explanation for h/2e Aharonov-Bohm oscillations, which are observed experimentally when the two spins of the lowest Landau level form bound states. We show that the edge channels may contain compressible regions, and using simple electrostatics, that the resonance through the outer spin sta...
متن کاملCoulomb drag in mesoscopic rings
We develop a Luttinger-liquid theory of the Coulomb drag of persistent currents flowing in concentric mesoscopic rings by incorporating nonlinear corrections to the electron dispersion relation. We demonstrate that at low temperatures, interactions between electrons in different rings generate an additional phase and thus alter the period of Aharonov-Bohm oscillations. The resulting nondissipat...
متن کاملAharonov-Bohm effect in the chiral Luttinger liquid
Edge states of the quantum Hall fluid provide an almost unparalled opportunity to study mesoscopic effects in a highly correlated electron system. In this paper we develop a bosonization formalism for the finite-size edge state, as described by chiral Luttinger liquid theory, and use it to study the Aharonov-Bohm effect. The problem we address may be realized experimentally by measuring the tun...
