Abstract

An electron, when added to a fractional quantum Hall fluid, famously splits into fractionally charged composite-fermion quasiparticles. We show here that a high energy composite fermion carrying a fractional charge decays into a collection of particles, including quasiparticles, quasiholes, and even whole electrons.

Kagome goldene with flat bands and Dirac nodal line fermions via line-graph epitaxy

The kagome lattice has emerged as a promising platform for investigating exotic quantum phases. However, achieving a single-atomic-layer kagome lattice in elemental materials remains a significant challenge. Here, we introduce line-graph epitaxy, a novel approach that enables the atomic-scale synthesis of goldene, a monolayer of elemental gold atoms arranged in a kagome lattice. Through scanning tunneling microscopy/spectroscopy (STM/STS), and density functional theory (DFT) calculations, we demonstrate the formation of kagome goldene, featuring a flat band with a van Hove singularity approximately 1.1 eV below the Fermi level, signaling strong electron correlation effects. Notably, the flat band is disrupted at the zigzag edges of goldene nanoflakes, revealing substantial edge effects. Furthermore, our calculations show that weak interlayer interactions between goldene and the underlying Au2Ge substrate generate dual Dirac nodal lines through a proximity effect. These findings offer not only a novel strategy for constructing elemental kagome lattices, but also a generalizable framework for fabricating and controlling line-graph materials. This research advances the exploration of quantum phases driven by strong correlations and the design of materials for next-generation quantum technologies.

Chirality-induced spin selectivity due to an emergent molecular orbital moment

The microscopic origin of chirality-induced spin selectivity (CISS), a phenomena where chiral molecules connected to a magnetic electrode show large spin-dependent conductance asymmetry even in ambient temperature, still remains an open question. Most of the existent theories are based on some sort of effective spin-orbit coupling or interfacial scattering, which do not provide satisfactory explanations for experimental observations such as the magnitude of spin polarization or the length dependence of the effect. We propose an alternative theoretical framework rooted in an intrinsic molecular contribution that shows a robust CISS effect and scales with the length of the molecule. The mechanism is based on the emergent molecular magnetic moment (MOM), which can produce experimentally observed point-symmetric I-V curves without violating the Onsager-Casimir reciprocity relation. The MOM has an intrinsic component that is governed by the chirality of the molecule and leads to finite CISS magnetoresistance and magnetochiral conductance asymmetry (MChA) that are even in bias voltage. By decomposing the MOM into its Fermi sea and Fermi surface components, we show that under strong bias, the MOM can be dominated by the Fermi surface contribution, which causes a sign change in the MChA leading to a behavior similar to that of electric magnetochiral anisotropy (eMChA). Finally, we analyze the effect of a magnetic field within the same framework, which may provide better insight into the crossover between CISS and eMChA.

Visualizing Chiral Edge Modes in Twisted Cuprate Superconductors via Scanning-Probe Quantum Sensing

Recently, unconventional superconductivity hosted by twisted van der Waals (vdW) heterostructures has received immense interest due to the exotic pairing symmetry, electronic interactions and nontrivial topological nature that are naturally relevant to the fast-advancing quantum technologies. Here, we report scanning-probe quantum sensing of nanoscale electromagnetic behaviors of twisted vdW cuprate superconductors. Using single-spin relaxometry, we directly visualize edge modes spontaneously formed in twisted Bi2Sr2CaCu2O8+x (BSCCO). By investigating temperature dependent variations of edge-state-induced quantum spin relaxation, we experimentally evaluate the magnitude of nontrivial topological band gap opened at nodal points in twisted BSCCO and its critical temperature behaviors under different twist angles. We further observe alternating chiral domains defined by edge modes, exploring experimental signatures of in-plane magnetic field-induced topology in 45° twisted BSCCO. Our results advance the current understanding of twisted vdW nodal superconductors, presenting an appealing high-temperature topological superconducting material platform for cutting-edge quantum innovation.
