A Novel Approach to Study Highly Correlated Nanostructures: The Logarithmic Discretization Embedded Cluster Approximation
E. V. Anda, G. Chiappe, C. A. Busser +4
This work proposes a new approach to study transport properties of highly correlated local structures. The method, dubbed the Logarithmic Discretization Embedded Cluster Approximat…
Phase Effects on the Conductance Through Parallel Double Dots
V. M. Apel, Maria A. Davidovich, G. Chiappe +1
Phase effects on the conductance of a double-dot system in a ring structure threaded by a magnetic flux are studied. The Aharonov-Bohm effect combined with the dot many-body chargi…
Effect of topology on the transport properties of two interacting dots
V. M. Apel, Maria A. Davidovich, E. V. Anda +2
The transport properties of a system of two interacting dots, one of them directly connected to the leads constituting a side-coupled configuration (SCD), are studied in the weak a…
Effect of a Variable-Spin Quantum Dot on a Wire Conductance
Maria A. Davidovich, E. V. Anda, C. A. Busser +1
A numerically exact calculation of the T=0 transport properties of a quantum wire interacting with a lateral two-level quantum dot is presented. The wire conductance is calculated…
Kondo Effect and Persistent Currents in a Mesoscopic Ring: Numerically Exact Results
E. V. Anda, C. Busser, G. Chiappe +1
We study the persistent current circulating along a mesoscopic ring with a dot side-coupled to it when threaded by a magnetic field. A cluster including the dot and its vicinity is…
Transport in Coupled Quantum Dots: Kondo Effect Versus Anti-Ferromagnetic Correlation
C. A. Büsser, E. V. Anda, A. L Lima +2
The interplay between the Kondo effect and the inter-dot magnetic interaction in a coupled-dot system is studied. An exact result for the transport properties at zero temperature i…
