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…

Doping a Wigner-Mott insulator: Exotic charge orders in transition metal dichalcogenide moiré heterobilayers
Yuting Tan, Pak Ki Henry Tsang, Vladimir Dobrosavljević and Louk Rademaker

Physical review research 5 4, 043190 (2023)

Recent experiments on TMD heterobilayers show a multitude of charge ordered phases, which are likely Wigner-Mott crystals. In this publication we study what happens if you dope away from the fractional fillings. This leads to yet more variety of exotic charge orders, from “standard” doped…

Universal Scaling near Band-Tuned Metal-Insulator Phase Transitions
Simone Fratini, Sergio Ciuchi, Vladimir Dobrosavljević and Louk Rademaker

Physical review letters 131 19, 196303 (2023)

We present a theory for band-tuned metal-insulator transitions based on the Kubo formalism. Such a transition exhibits scaling of the resistivity curves, in the regime where Tτ>1 or μτ>1, where τ is the scattering time and μ the chemical potential. At the critical value of the chemical…

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…

Spin-orbit coupling in transition metal dichalcogenide heterobilayer flat bands
Louk Rademaker

Physical review. B 105 19, 195428 (2022)

The valence flat bands in transition metal dichalcogenide (TMD) heterobilayers are shown to exhibit strong intralayer spin-orbit coupling. I show that symmetry constrains the spin-dependent complex phase of hopping terms in an effective tight-binding model of the valence flat bands. A perpendicular …

How to Recognize the Universal Aspects of Mott Criticality?
Yuting Tan, Vladimir Dobrosavljević and Louk Rademaker

Crystals 12 7, 932 (2022)

In this paper we critically discuss several examples of two-dimensional electronic systems displaying interaction-driven metal-insulator transitions of the Mott (or Wigner–Mott) type, including dilute two-dimension electron gases (2DEG) in semiconductors, Mott organic materials, as well as the…
