Phase Transitions in the Bilayer Quantum Hall Effect
N. Kumada, D. Terasawa, Y. Shimoda +6
We measured the magnetoresistance of bilayer quantum Hall (QH) effects at the fractional filling factor by changing the total electron density and the density difference be…

Maximum entanglement of quantum-dot systems with single excitation in the spin van der Waals model
A. Miranowicz, S. K. Ozdemir, M. Koashi +2
Time evolution of entanglement of N quantum dots is analyzed within the spin-1/2 van der Waals (or Lipkin-Meshkov-Glick) XY model. It is shown that, for a single dot initially exci…
