Topologically Protected Negative Entanglement

open access: yesAdvanced Science, EarlyView.
It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.

LEGO‐like Origami Robots Standardize Structure Design of Soft Robots

open access: yesAdvanced Science, EarlyView.
The paper proposes a comprehensive design framework that standardizes the soft robot development process as the assembly of LEGO‐like, off‐the‐shelf origami actuator modules. With actuators designed to accommodate thickness and an optimization‐based assembly strategy, it establishes a repeatable, systematic workflow that streamlines and accelerates ...

Electrically and Geometrically Tunable Photon Pair Entanglement from Ferroelectric Nematic Liquid Crystal

open access: yesAdvanced Science, EarlyView.
By exploiting the strong nonlinear optical response and controllable molecular ordering of ferroelectric nematic liquid crystals (FNLCs), these materials can serve as tunable sources of polarization‐entangled photons. Adjusting the sample geometry or applying an external electric field enables continuous control of the entanglement degree, advancing ...

Recent Advances in Mediator and Proton Relay Usage in Molecular Catalysis

open access: yesAdvanced Science, EarlyView.
The use of electron–proton transfer mediators, redox mediators, and proton relays in synergy with molecular catalysts in energy‐related small‐molecule and organic transformations is discussed, with a focus on recent advances. Linear free‐energy relationship and catalytic Tafel plots provide a systematic foundation for benchmarking these catalytic ...
