c-theorem and improvement in non-compact conformal field theories

Journal of High Energy Physics
Energy-momentum tensor in general conformal field theories have improvement ambiguity and it can affect the argument in deriving c-theorem. While the derivation of Zamolodchikov’s c-theorem is still formally valid with the improved energy-momentum tensor,

Machine Learning Guided Design of Nerve‐On‐A‐Chip Platforms with Promoted Neurite Outgrowth

Advanced Functional Materials, EarlyView.
Compared to labor‐intensive trial‐and‐error experimentation, a machine learning (ML)‐guided workflow, incorporating cell viability assays, data augmentation, ensemble modeling, and model interpretation, is developed to accelerate nerve‐on‐a‐chip optimization and uncover data‐driven design principles.

Metamaterial Adhesives‐Integrated Triboelectric Nanogenerators with Enhanced and Programmable Charge Generation and Adhesion

Advanced Functional Materials, EarlyView.
A metamaterial adhesive‐integrated triboelectric nanogenerator (MetaAdh‐TENG) that integrates nonlinear cuts and a TENG in a flexible adhesive film is presented. The MetaAdh‐TENG simultaneously provides enhanced charge generation and strong adhesion by controlling crack propagation during peeling.

Fatigue‐Resistant Mechanoresponsive Color‐Changing Hydrogels for Vision‐Based Tactile Robots

Advanced Materials, EarlyView.
Mechanoresponsive color‐changing materials that can reversibly and resiliently change color in response to stress are highly desirable for diverse technologies in optics, sensors, and robots; however, such materials are rarely achieved. This work reports a fatigue‐resistant mechanoresponsive color‐changing hydrogel that exhibits reversible, resilient ...

Manipulating Ferroelectric Topological Polar Structures with Twisted Light

Advanced Materials, EarlyView.
We demonstrate dynamic control of ferroelectric order in quasi‐2D CsBiNb2O7 using twisted ultraviolet light carrying orbital angular momentum. Our approach harnesses non‐resonant multiphoton absorption and induced strain to modulate topological of ferroelectric polarization textures.
