FQAH and Anyon Density-Wave Halo in Twisted Bilayer MoTe2

Published:Dec 29, 2025 17:03
1 min read
ArXiv

Analysis

This paper investigates the interplay between topological order and symmetry breaking phases in twisted bilayer MoTe2, a material where fractional quantum anomalous Hall (FQAH) states have been experimentally observed. The study uses large-scale DMRG simulations to explore the system's behavior at a specific filling factor. The findings provide numerical evidence for FQAH ground states and anyon excitations, supporting the 'anyon density-wave halo' picture. The paper also maps out a phase diagram, revealing charge-ordered states emerging from the FQAH, including a quantum anomalous Hall crystal (QAHC). This work is significant because it contributes to understanding correlated topological phases in moiré systems, which are of great interest in condensed matter physics.
Reference

“The paper provides clear numerical evidences for anyon excitations with fractional charge and pronounced real-space density modulations, directly supporting the recently proposed anyon density-wave halo picture.”

Quantum Tunneling in Twisted Bilayer Graphene Superlattices

Published:Dec 25, 2025 21:40
1 min read
ArXiv

Analysis

This paper explores how quantum tunneling of electrons is affected by the structure of twisted bilayer graphene (TBG) superlattices. It investigates the impact of factors like twist angle, barrier geometry, and defects on electron transmission. The research is significant because it provides insights into controlling electron transport in TBG, potentially leading to new nanoelectronic and quantum devices.
Reference

“The presence of defects, particularly at smaller twist angles, provides additional control of tunneling behavior, allowing complete suppression of Klein tunneling under certain conditions.”

Topological edge states in curved zigzag superlattices in nonlinear exciton-polaritons

Published:Nov 25, 2025 18:39
1 min read
ArXiv

Analysis

This article reports on research into topological edge states within a specific physical system (curved zigzag superlattices) using nonlinear exciton-polaritons. The focus is on a specialized area of physics, likely exploring novel quantum phenomena or applications in photonics. The use of 'ArXiv' as the source indicates this is a pre-print, meaning it has not yet undergone peer review.
Reference

“The article's abstract or key findings would be needed to provide a specific quote. Without that, a general statement about the research's focus on topological edge states and nonlinear exciton-polaritons is the best I can offer.”
