Long-range spin transport in asymmetric quadruple quantum dots configurations
David Fernández-Fernández, Johannes C. Bayer, Rolf J. Haug +1
We theoretically investigate long-range coherent charge transport in linear quadruple quantum dot (QQD) arrays under reduced symmetry configurations. Employing a master equation ap…

Unifying adiabatic state-transfer protocols with -hypergeometries
Christian Ventura Meinersen, David Fernandez-Fernandez, Gloria Platero +1
Adiabatic optimal control schemes are essential for advancing the practical implementation of quantum technologies. However, the vast array of possible adiabatic protocols, combine…

Hidden topology in flat-band topological insulators: Strong, weak and square-root topological states
Juan Zurita, Charles E. Creffield, Gloria Platero
In this Letter, we study a previously unexplored class of topological states protected by hidden chiral symmetries that are local, that is, that protect against any off-diagonal di…
