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…
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…
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…
Charge-ordered states in twisted MoTe
Sparsh Mishra, Tobias M. R. Wolf, Allan H. MacDonald
We analyze interaction-driven charge-density-wave (CDW) states in the spin-valley polarized first valence miniband of twisted MoTe (tMoTe) using an adiabatic mapping from t…
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 h…
Topological excitonic insulators in electron bilayers modulated by twisted hBN
Yongxin Zeng, Allan H. MacDonald, Nemin Wei
Equilibrium interlayer exciton condensation is common in bilayer quantum Hall systems and is characterized by spontaneous phase coherence between isolated layers. It has been predi…
Quantum Phases in Twisted Homobilayer Transition Metal Dichalcogenides
Bohao Li, Wen-Xuan Qiu, Fengcheng Wu +1
Twisted homobilayer transition metal dichalcogenides - specifically twisted bilayer MoTe and twisted bilayer WSe - have recently emerged as a versatile platform for strongl…
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 quant…
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…
Experimental signature of layer skyrmions and implications for band topology in twisted WSe2 bilayers
Fan Zhang, Nicolás Morales-Durán, Yanxing Li +13
Transition metal dichalcogenide (TMD) twisted homobilayers have been established as an ideal platform for studying strong correlation phenomena, as exemplified by the recent discov…
Ab-initio study of the energy competition between Γand K valleys in bilayer transition metal dichalcogenides
Sam Olin, Erekle Jmukhadze, Allan H. MacDonald +1
Moiré engineering in two-dimensional van der Waals bilayer crystals has emerged as a flexible platform for controlling strongly correlated electron systems. The competition between…
