Abstract:
The interplay of crystal symmetries and electron correlations often results into the formation of unconventional magnetism beyond the traditional forms, arising from the long-range order of magnetic dipole moments. Detection of such hidden orders is a key challenge in condensed matter physics. Here, we present a theory for symmetry-broken chiral ground states and a methodology based on circularly polarized spin-selective angular-resolved photoelectron spectroscopy to probe them. We exploit the archetypal quantum material Sr2RuO4 and consider the nature of spectroscopic signatures which may be reconciled with the formation of spin-orbital chiral currents at the material surface.

Mario Cuoco, Senior Researcher, CNR-SPIN, Italy. My research activity focuses on modelling and computation of electronic, magnetic, transport and spectroscopic properties of correlated electron systems, topological phases, unconventional superconductivity, and superconducting magneto-electric effects. Awarded as Marie-Curie Research Fellow at CNRS Grenoble. Coordinator of FP7 project MAMA- “Multifunctional Advanced MAterials and nanoscale phenomena”. Task leader for “Fundamental Understanding” within the Cost-Action TO-BE “Towards Oxide Based Electronics”. Supervisor of the IEF-Marie Curie UFOX “Unveiling functional properties of hybrid oxides”. He has contributed to several EU and national projects, e.g. CNQT- FET Open for curved topological materials, Quantera QUANTOX “QUANtum Technologies with 2D-Oxides” and TOPSPIN PRIN projects. He is currently involved (WP leader) in the SUPERGATE “Gate Tuneable Superconducting Quantum Electronics” FET-Open project as well as in the National Quantum Science and Technology Institute PNRR project.
