Stripe antiferromagnetism and chiral superconductivity in tWSe
Erekle Jmukhadze, Sam Olin, Allan H. MacDonald +1
The layer-dependent Hamiltonians of parallel-stacked MoTe and WSe homobilayer moiré materials are topologically non-trivial, both in real space and in momentum space, and…
Coexisting Charge Density Wave and Superconducting Order in Quantizing Magnetic Fields
Ron Q. Nguyen, Peiyu Qin, Hai-Tian Wu +12
Charge density wave (CDW) and superconductivity are both common in strongly interacting electron systems. While CDW order is ubiquitous in both quantum Hall systems and unconventio…
Emergent Trion Resonance Driven by Lattice Reconstruction in a Moiré Superlattice
Zhida Liu, Haonan Wang, Xiaohui Liu +20
We investigate how many-electron excited states emerge in twisted MoSe2 homobilayers when the lattice reconstructions evolve. Notably, we identify a new trion resonance that arises…
Transition Metal Dichalcogenide Excitons in Periodic Electrostatic Potentials: Center-of-Mass Models
Jose M. Torres-Lopez, Sudipta Kundu, Felipe H. da Jornada +2
Two-dimensional (2D) van-der-Waals materials are a promising platform for exciton state engineering. In this paper, we study the properties of excitons in 2D group VI transition-me…
Theory of magnetoroton bands in moiré materials
Bishoy M. Kousa, Nicolás Morales-Durán, Tobias M. R. Wolf +2
The recent realization of Hofstadter spectra and fractional Chern insulators in moiré materials has introduced a new ingredient, a periodic lattice potential, to the study of quan…
Half-quantized anomalous Hall conductance in topological insulator/ferromagnet van der Waals heterostructures
Shahid Sattar, Roman Stepanov, Alexander Tyner +3
The half-quantized anomalous Hall conductance (AHC) in topological materials is a condensed matter physics realization of the parity anomaly of (2+1) quantum field theory and an im…
