Light-induced States and Phase Transitions in Quantum Materials investigated by Photoemission Spectroscopy and Epitaxial Synthesis
… delve into three compelling studies: (1) Floquet-Bloch states, photon-dressed Bloch states, were investigated in graphene. These states are generated by a time-periodic potential of light, closely related to the topic of Floquet engineering. (2) A light-induced insulator-to-metal …

Phase transitions in quasiperiodic and driven optical lattices
… with a novel lattice geometry, and the use of Floquet driving to engineer behaviours qualitatively different from static systems. In particular I will present our work using periodic driving to make a continuous quantum phase transition become discontinuous, which to our knowledge has never …

Artificial gauge fields and quantum hall physics in optical lattices
The engineering of artificial gauge fields for ultracold atoms in optical lattices opens a new chapter for the quantum simulation of quantum Hall physics. Motivated by recent advances and refined techniques in controlling quantum gases in optical lattices, this thesis explores how the …

Manipulation and analysis of topological properties in hybrid Dirac materials [Manipolazione ed analisi delle proprietà topologiche dei materiali di Dirac]
… a linea nodale ingegnerizzati tramite campi Floquet e le eterostrutture superconduttive a base di grafene. Nella prima parte della tesi, studiamo gli stati di interfaccia che emergono quando due regioni di un semimetallo a linea nodale sono illuminate da fasci di luce con polarizzazioni …
