Frustrated Quantum Magnets

A description of different phases of two dimensional magnetic insulators is given. The first chapters are devoted to the understanding of the symmetry breaking mechanism in the semi-classical Néel phases. Order by disorder selection is illustrated. All these phases break SU(2) symmetry and are gapless phases with ∆Sz = 1 magnon excitations. Different gapful quantum phases exist in two dimension...

Effect of asymmetric quantum dot rings in electron transport through a quantum wire

The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

Symmetry lowering in extreme-electron-density perovskite quantum wells.

We report on structural distortions in extreme-electron density (∼6×10(14)  cm(-2)) confined quantum wells of SrTiO3 embedded in GdTiO3. Sr-column displacements are measured using high-angle annular dark-field imaging in scanning transmission electron microscopy. Using thick SrTiO3 layers as a reference, orthorhombic-like Sr-site displacements are observed when SrTiO3 quantum wells are thinner ...
