Circular Polarimetric Imaging with a Metamaterial Integrated Long‐Wavelength Infrared Focal Plane Array

Advanced Science, EarlyView.
A quantum well infrared photodetector based long‐wavelength infrared division‐of‐focal‐plane‐array circular polarimeter featuring a 320 × 256 pixel array integrated with a chiral meta‐mirror structure array is established. The device achieves a circular polarization extinction ratio of 5.67, a 9.13‐fold enhancement in responsivity, a noise equivalent ...

Enhancing the Self‐Assembly of Step‐Growth Polymers by Narrowing Their Molar Mass Distribution: A Dynamic Bond‐Mediated Approach

Angewandte Chemie, EarlyView.
The study introduces asymmetric dynamic bond‐mediated polymerization (ADBP), a method to narrow molar mass distributions in step‐growth polymers via asymmetric, reversibly‐deactivated AA'‐type electrophiles. ADBP initially forms low‐dispersity dimers/trimers, later polymerizing into polyurethanes with controlled dispersities (Đ ≤ 1.5), yielding ...

Thermal Control of Vortex Motion in Nanoscale Superconductors

Advanced Electronic Materials, EarlyView.
Vortices in superconducting film can be thermally steered by a local heating from a tip. The work shows that the vortex is attracted by the hot spot by a force that emulates an electric field resulting in a fictious Lorentz‐force on the vortex. Abstract Thermally induced motion of vortices in nanoscale superconductors (SCs) is investigated.

Conformal symmetry in quantum gravity

European Physical Journal C: Particles and Fields
We study the problem of how to derive conformal symmetry in the framework of quantum gravity. We start with a generic gravitational theory which is invariant under both the general coordinate transformation (GCT) and Weyl transformation (or equivalently,

Voltage‐Induced Hysteretic Resistance in Nematic Order of SmFeAsO

Aggregate, EarlyView.
Electronic origin of nematicity revealed! This study uncovers a unique voltage‐driven hysteresis effect in the SmFeAsO's nematic phase through the advanced point‐contact spectroscopy. A bias voltage drives the point contact through antiferromagnetic and structural transitions via the ballistic Joule heating effect, revealing a distinctive hysteretic ...
