38. Elettra 2.0: new advances in synchrotron radiation research

Dr Luca Gregoratti (Elettra - Sincrotrone Trieste S.C.p.A.)

12/3/24, 8:45 AM

Elettra 2.0 represents the latest evolution of Italy's third-generation synchrotron radiation facility, which has served scientific and industrial communities since 1993. Approved by the Italian Government in 2017, the Elettra 2.0 project involves replacing the current machine with a low-emittance storage ring, marking a significant milestone in synchrotron research. With enhanced brightness...

36. Three different charge orders in kagome lattice materials

Dr Min Gu Kang (Cornell University)

12/3/24, 9:15 AM

Invited Oral

Kagome lattice is one of the most fertile geometric motifs in condensed matter physics, where a unique interplay between topology, correlation, and frustration gives rise to a plethora of quantum phenomena. Charge ordering is an example of quantum states prevalently observed in various Kagome lattice materials, including AV3Sb5, ScV6Sn6, and FeGe, and is found to be intertwined with...

14. The rich physics of bilayer kagome metals

Prof. Domenico Di Sante (University of Bologna)

12/3/24, 9:45 AM

Invited Oral

Long-range electronic order descending from a metallic parent state constitutes a rich playground to study the intricate interplay of structural and electronic degrees of freedom. Kagome materials appeared as the perfect stage for such explorations. Specifically, RV6Sn6 (R = rare earth atom) bilayer kagome metals are topological systems with Dirac-like itinerant states, van Hove singularities...

15. 2D twistronics

Prof. Neil Wilson (University of Warwick)

12/3/24, 10:45 AM

Invited Oral

The wide family of 2D materials (2DMs) includes metals, semiconductors, superconductors, dielectrics, ferroics and more, each displaying novel phenomena due to the qualitatively different nature of interactions in 2D. However, the real delight is in the ability to combine different 2D materials into atomically defined heterostructures by simply stacking layers, engineering interactions between...

23. Kramers-Weyl fermions in chiral crystals

Dr Alberto Crepaldi (Politecnico di Milano)

12/3/24, 11:15 AM

Invited Oral

The study of chiral crystals is one of the frontiers in the field of topological materials. Weyl fermions with unique properties emerge in the absence of inversion and mirror symmetries [1]. Kramers-Weyl fermions, for example, are pinned at different high-symmetry points and surface arcs can connect them spanning over the entire Brillouin zone [2 - 4]. The physics of chiral crystals is further...

22. Signatures of surface spin-orbital chiral metal

Dr Federico Mazzola (CNR-SPIN)

12/3/24, 11:45 AM

Invited Oral

Surface experimental probes, such as angle-resolved photoelectron spectroscopy provide researchers access to the electronic structure of solids. Despite the advances in the field, recently, new forms of surface local magnetism completely different from standard descriptions have appeared. One example of such forms of magnetism are the one generated by the so-called loop currents, generated by...
