Breathing mode of rapidly rotating Bose-Einstein condensates

open access: yes, 2006
We show that the breathing mode of a rapidly-rotating, harmonically-trapped Bose-Einstein condensate may be described by a generalized lowest Landau level (LLL) wave function, in which the oscillator length is treated as a variable.

Correlated Dual‐Gradient Electrodes Enabling Spatially Synchronized Sulfur Redox in High‐Mass‐Loading Li–S Batteries Under High Current Densities

open access: yesAdvanced Materials, EarlyView.
Coupling a dual‐gradient carbonized framework with Fe2O3/Fe‐N‐C catalytic sites enables spatially synchronized sulfur redox across the entire electrode thickness in high‐mass‐loading Li–S batteries. This synergistic structural–catalytic design effectively mitigates concentration, ohmic, and electrochemical polarization, thereby achieving high‐capacity ...

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes

open access: yesAdvanced Materials, EarlyView.
Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications

open access: yesAdvanced Materials, EarlyView.
In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...

Atomically Resolved Acoustic Dynamics Coupled with Magnetic Order in a Van der Waals Antiferromagnet

open access: yesAdvanced Materials, EarlyView.
Magnetically coupled acoustic phonon modes (f1, f2, f3) are captured by ultrafast X‐ray diffraction in a prototypical van der Waals antiferromagnet FePS3, including their atomic displacement vectors (u) and the acoustic propagation wave vectors (k). Notably, the atomic displacement vector and amplitude of these modes, represented by the direction and ...
