Explicit and Hidden Symmetries in Quantum Dots and Quantum Ladders
K. Kikoin, Y. Avishai, M. Kiselev
The concept of dynamical hidden symmetries in the physics of electron tunneling through composite quantum dots (CQD) and quantum ladders (QL) is developed and elucidated. Quite gen…
Kondo effect in systems with dynamical symmetries
Tetyana Kuzmenko, Konstantin Kikoin, Yshai Avishai
This paper is devoted to a systematic exposure of the Kondo physics in quantum dots for which the low energy spin excitations consist of a few different spin multiplets $|S_{i}M_{i…
Two-channel Kondo tunneling in triple quantum dot
T. Kuzmenko, K. Kikoin, Y. Avishai
The effective spin Hamiltonian of a triple quantum dot with odd electron occupation weakly connected in series with left () and right () metal leads is composed of two-channe…
Electric Field Induced Kondo Tunneling Through Double Quantum Dot
M. N. Kiselev, K. Kikoin, L. W. Molenkamp
It is shown that the resonance Kondo tunneling through a double quantum dot (DQD) with even occupation and singlet ground state may arise at a strong bias, which compensates the en…
Dimensional Crossover in 2D Crossbars
K. Kikoin, I. Kuzmenko, S. Gredeskul +1
Spectrum of boson fields and two-point correlators are analyzed in quantum crossbars (QCB, a superlattice formed by two crossed interacting arrays of quantum wires), with short ran…
Kondo effect in optics of quantum dots
K. Kikoin, Y. Avishai
Anderson impurity model for semiconductor quantum dot is extended to take into account both particle and hole branches of charge excitations. It is shown that in dots with even num…
