Record‐High Birefringence Achieved by Linearly Extended π‑Conjugated Building Blocks in Metal‐Free Sulfate

ABSTRACT The advancement of birefringent materials is critical for next‐generation integrated photonics, yet conventional systems face intrinsic limitations in birefringence magnitude. Sulfate crystals offer a promising platform but have been hindered by their dependence on speci...

Wafer-scale low-symmetry graphene moiré superlattice for integrated quantum rectifiers

Low-symmetry materials unlock rich Berry curvature physics and anomalous transport phenomena that are forbidden in high-symmetry quantum systems through rigorous crystalline symmetry constraints. Current approaches rely on external fields or complex heterogeneous stacking to brea...

Odd‐even effects in molecular junctions: A Solomonic resolution of conflicting reports on conductance trends, metal specificity, and microscopic origin

Abstract Odd–even conductance alternation in alkanethiol (CnT, –12) self‐assembled monolayers has been debated for two decades, with conflicting reports on trends, metal dependence, and microscopic origin. Using conducting probe atomic force microscopy (CP‐AFM) with Ag, Au, and P...

Direct experimental test of Feynman’s path integral postulates with single photons

The experimental validation of fundamental thought experiments in quantum mechanics has profoundly advanced quantum science and technology while deepening our understanding of quantum mechanics. However, experimental studies of the path integral formulation, a cornerstone of quan...

Experimental causal inference from measurements alone in the presence of spatial and temporal quantum correlations

The causal structure of a set of events specifies which events influence which others. Determining this structure, known as causal inference, is a fundamental task in science. Reset-style intervention is commonly used to determine causal structure in classical scenarios. However,...
