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…

Transport in a mesoscopic ring with a quantum dot: from the Coulomb blockade regime to the Kondo effect
Valeria Ferrari, Guillermo Chiappe, Enrique Anda
The system described in this work consists of a quantum dot inserted in a mesoscopic ring threaded by a magnetic flux. Our aim is to present a complete description for this device…

Non Linear Effects in Resonant Tunneling Throught a Quantum Dot
E. S. Rodrigues, E. V. Anda, P. Orellana
We study non-linear phenomena in quantum dots. Non linearities are reflected in the I-V characteristic curve as bistabilities, instabilities and time dependent oscillations of the…
