Finite electron crystallites in strong magnetic fields: Precursors of a supersolid?
Yuesong Li, Constantine Yannouleas, Uzi Landman
We show that a supersolid phase, exhibiting simultaneously solid and superfluid behavior, properly describes the finite electron crystallites that form in two-dimensional quantum d…
Electron localization and entanglement in a two-electron quantum dot
Constantine Yannouleas, Uzi Landman
Calculations for two electrons in an elliptic quantum dot, using symmetry breaking at the unrestricted Hartree-Fock level and subsequent restoration of the broken parity via projec…
Theoretical Considerations About the Generation and Properties of Narrow Electron Flows in Solid State Structures
R. N. Gurzhi, A. N. Kalinenko, A. I. Kopeliovich +3
A method for the evaluation of the angular width of an electron beam generated by a nanoconstriction is proposed and demonstrated. The approach is based on analysis of a narrow-wid…
Spin-Guide: A New Source of High Spin-Polarized Current
R. N. Gurzhi, A. N. Kalinenko, A. I. Kopeliovich +3
We propose a ``spin-guide'' source for generation of electric currents with a high degree of spin polarization, allowing long-distance transmission of the spin-polarization. In the…
Two-dimensional few electron systems in high magnetic fields: Composite-fermion or rotating-electron-molecule approach?
Constantine Yannouleas, Uzi Landman
A new class of analytic and parameter-free, strongly correlated wave functions of simple functional form is derived for few electrons in two-dimensional quantum dots under high mag…
Magnetic-field Manipulation of Chemical Bonding in Artificial Molecules
Constantine Yannouleas, Uzi Landman
The effect of orbital magnetism on the chemical bonding of lateral, two-dimensional artificial molecules is studied in the case of a 2e double quantum dot (artificial molecular hyd…
