CV

Diego Frustaglia studied physics at University of Buenos Aires (1991-1993) and Balseiro Institute (1993-1996), Argentina. After graduation, in 1997 he moved as a doctoral student to the Max-Planck Institute for Physics of Complex Systems in Dresden, Germany. He obtained his PhD in 2001 from the Technical University of Dresden with a thesis work on quantum-transport theory. After postdoctoral stays at University of Karlsruhe (2001-2003), Germany, and Scuola Normal Superiore (2003-2007), Pisa, Italy, he joined the University of Seville, Spain, in 2007 as a tenure-track “Ramón y Cajal” Research Associate. Since 2012, he is an Associate Professor at University of Seville.

Prof. Frustaglia is a quantum theorist with an interest in experimental design and implementation. His research work has contributed to the fields of spin-electronics, quantum chaos, geometric and topologic phases, solid-state quantum information, and quantum correlations.

Geometric and Topological Resources for Spin Control

We aim to identify optimal tools for the manipulation of quantum spin states by engineering geometric and topological resources at reach in mesoscopic solid-state systems.

Electronic nanostructures are an ideal laboratory for studying the foundations of quantum mechanics. At the same time, they represent the paradigm of quantum-information technology for the development of new (quantum) formats of computation and communication, especially those relying on spin physics. A key resource is the possibility to tailor internal (spin-orbit) and external fields, resulting in a variety of hybrid magnetic textures. Our goal is to achieve a controlled manipulation of spin dynamics by exploiting the geometrical (local) and topological (global) properties of the effective fields as distinct resources in semiconducting nanocircuits, the working principle of which is spin interferometry. Specifically, we shall study the relevant mechanisms that can switch the spin dynamics between phases of different topological characteristics and modify the global properties dramatically (reflected in an observable such as the conductance) by tuning a control parameter (a magnetic or electric field) accessible to the state-of-the-art technologies. Similar phenomena are displayed in other two-level quantum systems as, e.g., strongly-driven superconducting qubits, which shall be also a subject of our study. The main activity will consist in the development of theoretical and numerical models for the design of experiments.
