Dephasing in a quantum dot coupled to a quantum point contact
Tomosuke Aono
We investigate a dephasing mechanism in a quantum dot capacitively coupled to a quantum point contact. We use a model which was proposed to explain the 0.7 structure in point conta…
Chaotic scattering through coupled cavities
Kazutaka Takahashi, Tomosuke Aono
We study the chaotic scattering through an Aharonov-Bohm ring containing two cavities. One of the cavities has well-separated resonant levels while the other is chaotic, and is tre…
Two impurity Kondo problem under Aharonov--Bohm and Aharonov--Casher Effects
Tomosuke Aono
We investigate electron transport under the two impurity Kondo problem with the Aharonov--Bohm and Aharonov--Casher effects. These interference effects induce the Ising-coupled Rud…
Suppression of Shot Noise in Quantum Point Contacts in the "0.7" Regime
A. Golub, T. Aono, Yigal Meir
Experimental investigations of current shot noise in quantum point contacts show a reduction of the noise near the 0.7 anomaly. It is demonstrated that such a reduction naturally a…
Mesoscopic conductance fluctuations in a coupled quantum dot system
Kazutaka Takahashi, Tomosuke Aono
We study the transport properties of an Aharonov-Bohm ring containing two quantum dots. One of the dots has well-separated resonant levels, while the other is chaotic and is treate…
Duality in the Kondo model and perturbative approach to strong coupling theory
Tomosuke Aono
We investigate the duality in the Kondo model. Starting from the s-d model with the coupling constant , the strong coupling model with the constant of 1/J is identified. The mod…
