Thermopower of a Kondo-correlated quantum dot
R. Scheibner, H. Buhmann, D. Reuter +2
The thermopower of a Kondo-correlated gate-defined quantum dot is studied using a current heating technique. In the presence of spin correlations the thermopower shows a clear devi…
Ferrimagnetic mixed-spin ladders in weak and strong coupling limits
D. N. Aristov, M. N. Kiselev
We study two similar spin ladder systems with the ferromagnetic leg coupling. First model includes two sorts of spins, s= 1/2 and s= 1, and the second model comprises only s=1/2 le…
Current heating of a magnetic 2DEG in HgMnTe/HgCdTe quantum wells
Y. S. Gui, C. R. Becker, J. Liu +5
Heating caused by electrons with excess kinetic energy has been investigated in a magnetic two-dimensional electron gas, M2DEG, in HgMnTe/HgCdTe(001) quantum wells. The temperature…
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…
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…
