Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

Measuring topological invariants for higher-order exceptional points in quantum three-mode systems

Nature Communications
Owing to the presence of exceptional points (EPs), non-Hermitian (NH) systems can display intriguing topological phenomena without Hermitian analogs. However, experimental characterizations of exceptional topological invariants have been restricted to ...

Heisenberg-limited single-mode quantum metrology in a superconducting circuit

Nature Communications, 2019
Reaching a quantum advantage in metrology usually requires hard-to-prepare two-mode entangled states such as NOON states. Here, instead, the authors demonstrate single-mode phase estimation using Fock states superpositions in a superconducting qubit ...

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...
