The NonCommutative Geometry of the Quantum Hall Effect
, 2002
"... A mathematical framework based on NonCommutative Geometry is proposed to described the Integer Quantum Hall Effect. It takes localization effects into account. It permits to prove rigorously that the Hall conductivity is quantized and that plateaus occur when the Fermi energy varies in a region of ..."

The electronic properties of graphene
 Rev. Mod. Phys. 2009
"... This article reviews the basic theoretical aspects of graphene, a oneatomthick allotrope of carbon, with unusual twodimensional Diraclike electronic excitations. The Dirac electrons can be controlled by application of external electric and magnetic fields, or by altering sample geometry and/or t ..."

/or topology. The Dirac electrons behave in unusual ways in tunneling, confinement, and the integer quantum Hall effect. The electronic properties of graphene stacks are discussed and vary with stacking order and number of layers. Edge �surface � states in graphene depend on the edge termination �zigzag
ARTICLES Roomtemperature coherent coupling of single spins in diamond
, 2006
"... Coherent coupling between single quantum objects is at the very heart of modern quantum physics. When the coupling is strong enough to prevail over decoherence, it can be used to engineer quantum entangled states. Entangled states have attracted widespread attention because of applications to quantu ..."

Quantum Quivers and Hall/Hole Halos
, 2002
"... Two pictures of BPS bound states in CalabiYau compactifications of type II string theory exist, one as a set of particles at equilibrium separations from each other, the other as a fusion of Dbranes at a single point of space. We show how stringy quiver quantum mechanics smoothly interpolates be ..."

A crucial ingredient is a
A Roomtemperature Ultrafast Spinpolarized Polariton Laser
"... Lightmatter interactions are greatly altered in resonators and heterostructures where both electrons and photons are confined. These interactions lead to nonlinear optical processes and lasing where both photon mode control and electron quantum confinement play a role. Lasing in semiconductors is g ..."

. In principle, optical or electrical injection of spinpolarized carriers can reduce the lasing threshold6 and switching time7. Here, we demonstrate roomtemperature spinpolarized ultrafast (sub10ps) pulsed lasing in a highly optically excited GaAs microcavity embedded with InGaAs multiple quantum wells
ROOMTEMPERATURE FUNCTIONAL NANOELECTRONIC DEVICES AND CIRCUITS WITH BALLISTIC JUNCTIONS
"... Present digital logic gates are primarily built from field effect transistors (FETs) such as complementary metal oxide semiconductors with the gate length in the deep subµm regime. As device feature sizes approach the nanometer regime, fundamental physical constraints and increasingly prohibitive e ..."

These devices function at room temperature, and the device layout features fabrication by a singlestep lithography process that is suitable for mass production with lowcost approaches such as nanoimprint
Quantum Hall Effect

"... We show that a large class of incompressible quantum Hall states correspond to different representations of the W ∞ algebra by explicit construction of the second quantized generators of the algebra in terms of fermion and vortex operators. These are parametrized by a set of integers which are relat ..."
