Spin precession and laser-induced spin-polarized photocurrents
Esteban A. Rodríguez-Mena, Matías Berdakin, Luis E. F. Foa Torres
Controlling spin currents in topological insulators (TIs) is crucial for spintronics but challenged by the robustness of their chiral edge states, which impedes the spin manipulati…
Dressed basis sets for the modeling of exchange interactions in double quantum dots
Mauricio J. Rodríguez, Esteban A. Rodríguez-Mena, Ahmad Fouad Kalo +1
We discuss the microscopic modeling of exchange interactions between double semiconductor quantum dots used as spin qubits. Starting from a reference full configuration interaction…
A two-dimensional 10-qubit array in germanium with robust and localised qubit control
Valentin John, Cécile X. Yu, Barnaby van Straaten +10
Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for \textit{in situ} electric fast and hi…
Spin-polarized tunable photocurrents
Matías Berdakin, Esteban A. Rodríguez-Mena, L. E. F. Foa Torres
Harnessing the unique features of topological materials for the development of a new generation of topological based devices is a challenge of paramount importance. Using Floquet s…
