The Kondo state in quantum point contacts and the local moment in semiconductor quantum dots - two sides of the same phenomenon
Daniel L. Miller
This is a three step work: i) we explain why quantum point contacts are similar to ballistic quantum dots; ii) we introduce the virtual Kondo state in both systems; iii-1st) this s…
Zigzag theory of localization in quantum chaos
Daniel L. Miller
This paper has been withdrawn by the author, due a crucial error in Eq. 6.
About common physical nature of divergence and interference
Daniel L. Miller
The difference of actions between nearly lying unstable ``8'' and ``0'' like trajectories in two dimensions is computed by methods of chaotic dynamics. We found it to be equal to $…
Hikami boxes and the Sinai billiard
Daniel L. Miller
Diagram, known in theory of the Anderson localization as the Hikami box, is computed for the Sinai billiard. This interference effect is mostly important for trajectories tangent t…
Inhomogeneous states in quantum dots. I
Daniel L. Miller
In this work we show that the Anderson impurity model applied to ``scar'' wave function may explain large fluctuations of ground state energy of electron gas in a quantum dot.
Compressibility of electron gas in presence of Anderson's impurity
Daniel L. Miller
We employ Wiegmann's solution of the Anderson impurity model in order to compute the compressibility of electron gas. We have found that there is a pair of neighbor levels separate…
