Real-Space Imaging of Band Topology via Wavefunction Zeros

Julian Ingham, Raquel Queiroz

We prove that the wavefunction of a crystal at a high-symmetry momentum, , has symmetry-enforced zeros at certain positions in the unit cell,…

Magnetic Signatures of a Putative Fractional Topological Insulator in Twisted MoTe2

Yiping Wang, Gillian E. Minarik, Weijie Li +15

The interplay among electronic correlation, topology, and time-reversal-symmetry (TRS) often leads to exotic quantum states of matter, as highlighted by the discoveries of fraction…

Twist-angle evolution of the intervalley-coherent antiferromagnet in twisted WSe

Daniel Muñoz-Segovia, Valentin Crépel, Raquel Queiroz +1

Recent experimental reports of correlated physics in twisted homobilayer WSe have spurred interest in the interplay of electronic interactions and topology in this system. Here…

Flat band excitons in a three-dimensional supertwisted spiral transition metal dichalcogenide

Yinan Dong, Yuzhou Zhao, Lennart Klebl +19

A new frontier in van der Waals twistronics is the development of three-dimensional (3D) supertwisted materials, where each successive atomic layer rotates by the same angle. While…

Roadmap for Photonics with 2D Materials

F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145

Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…

Hidden States and Dynamics of Fractional Fillings in tMoTe2 Moiré Superlattices

Yiping Wang, Jeongheon Choe, Eric Anderson +14

The fractional quantum anomalous Hall (FQAH) effect was recently discovered in twisted MoTe2 bilayers (tMoTe2). Experiments to date have revealed Chern insulators from hole doping…
