Quantum mechanics is at the heart of our technology and economy - the laser and the transistor are quantum devices - but its full potential is far from being realized. Recent technological advances in optics, nanoscience and engineering allow experimentalists to create artificial structures or put microscopic and mesoscopic systems under new manipulable conditions in which quantum phenomena play a fundamental role.

Quantum technologies exploit these effects with practical purposes. The objective of Quantum Science is to discover, study, and control quantum efects at a fundamental level. These are two sides of a virtuous circle: new technologies lead to the discovery and study of new phenomena that will lead to new technologies.

Our aim is  to control and understand quantum phenomena in a multidisciplinary intersection of  Quantum Information, Quantum optics and cold atoms, Quantum Control, Spintronics, Quantum metrology, Atom interferometry, Superconducting qubits and Circuit QED and Foundations of Quantum Mechanics.

QUINST is funded in part as a “Grupo Consolidado” from the Basque Government (IT472-10, IT986-16, IT1470-22)  and functions as a network of groups with their own funding, structure, and specific goals.

Title: Electrically Reversible Spin Polarization in Honeycomb Lattices

The spin-split states subject to spin-orbit coupling in two-dimensional systems has long been accepted as pointing in-plane and perpendicular to the corresponding wave vectors. This is in general true for free electron model, but exceptions do exist. We unveil the unusual upstanding behavior of those spins around high-symmetry points in honeycomb lattices. Our calculation  explains the recent experiment of the Tl/Si(111)-1x1 surface alloy [PRL 102,
096805 (2009)], where abrupt upstanding spin states near these points have been observed, and predicts an electrically reversible out-of-plane surface spin polarization. These results extend the ability of spin manipulation by electric field,
which is one of the goals of modern spintronics.
