Physical review letters 131 4, 046401 (2023)

The recent observation of correlated phases in transition metal dichalcogenide moir\’e systems at integer and fractional filling promises new insight into metal-insulator transitions and the unusual states of matter that can emerge near such transitions. Here, we combine real- and momentum-space…

Black phosphorus (BP) stands out among two-dimensional (2D) semiconductors because of its high mobility and thickness dependent direct band gap. However, the quasiparticle band structure of ultrathin BP has remained inaccessible to experiment thus far. Here we use a recently developed laser-based…

Multiple antiferromagnetic phases and magnetic anisotropy in exfoliated CrBr3 multilayers
Fengrui Yao, Volodymyr Multian, Zhe Wang, Nicolas Ubrig, Jérémie Teyssier, Fan Wu, Enrico Giannini, Marco Gibertini, Ignacio Gutierrez Lezama and Alberto Morpurgo

Nature communications 14 1, 4969 (2023)

In twisted two-dimensional (2D) magnets, the stacking dependence of the magnetic exchange interaction can lead to regions of ferromagnetic and antiferromagnetic interlayer order, separated by non-collinear, skyrmion-like spin textures. Recent experimental searches for these textures have focused on …

Determining spin-orbit coupling in graphene by quasiparticle interference imaging
Lihuan Sun, Louk Rademaker, Diego Mauro, Alessandro Scarfato, Arpad Pasztor, Ignacio Gutierrez Lezama, Zhen Wang, José Martinez Castro, Alberto Morpurgo and Christoph Renner

Nature communications 14 1, 3771 (2023)

Inducing and controlling spin-orbit coupling (SOC) in graphene is key to create topological states of matter, and for the realization of spintronic devices. Placing graphene onto a transition metal dichalcogenide is currently the most successful strategy to achieve this goal, but there is no…
