Spin gap and string order parameter in the ferromagnetic Spiral Staircase Heisenberg Ladder: a quantum Monte Carlo study
C. Brünger, F. F. Assaad, S. Capponi +3
We consider a spin-1/2 ladder with a ferromagnetic rung coupling J_\perp and inequivalent chains. This model is obtained by a twist (θ) deformation of the ladder and interpolates b…
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…
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…
