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,…
Candidate for a 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…
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…
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…
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…
Real-Space Imaging of the Band Topology of Transition Metal Dichalcogenides
Madisen Holbrook, Julian Ingham, Daniel Kaplan +11
The topological properties of Bloch bands are intimately tied to the structure of their electronic wavefunctions within the unit cell of a crystal. Here, we show that scanning tunn…
Electronic Bound States in the Continuum in a 2D Metal
Morgan Thinel, Simon Turkel, Sebastian E. Rossi +11
Bound states in the continuum (BICs) are quantum states that remain localized despite existing within a continuum of extended, delocalized states. They defy conventional wave theor…
Pomeranchuk Instability Induced by an Emergent Higher-Order van Hove Singularity on the Distorted Kagome Surface of CoSnS
Pranab Kumar Nag, Rajib Batabyal, Julian Ingham +11
Materials hosting flat bands at the vicinity of the Fermi level promote exotic symmetry broken states. Common to many of these are van Hove singularities at saddle points of the di…
Frustrated hopping from orbital decoration of a primitive two-dimensional lattice
Aravind Devarakonda, Christie S. Koay, Daniel G. Chica +18
Materials hosting flat electronic bands are a central focus of condensed matter physics as promising venues for novel electronic ground states. Two-dimensional (2D) geometrically f…
Electronic interactions in Dirac fluids visualized by nano-terahertz spacetime interference of electron-photon quasiparticles
Suheng Xu, Yutao Li, Rocco A. Vitalone +15
Ultraclean graphene at charge neutrality hosts a quantum critical Dirac fluid of interacting electrons and holes. Interactions profoundly affect the charge dynamics of graphene, wh…
Semi-Dirac Fermions in a Topological Metal
Yinming Shao, Seongphill Moon, A. N. Rudenko +14
Topological semimetals with massless Dirac and Weyl fermions represent the forefront of quantum materials research. In two dimensions (2D), a peculiar class of fermions that are ma…
