Bioinspired Mechanisms and Actuation of Soft Robotic Crawlers

Advanced Science, EarlyView.
Researchers have been developing soft materials and robotic crawlers inspired by soft‐bodied animals to mimic effective crawling in complex environments. This review explores the state‐of‐the‐art in soft crawlers, highlighting the interaction between materials, crawling mechanisms, actuation, and applications. The review concludes by providing insights

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities

Advanced Science, EarlyView.
This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal

Spontaneous Supersymmetry Breaking and Nambu-Goldstone Modes in Interacting Majorana Chains [PDF]

arXiv
In modern physics, spontaneous symmetry breaking is one of the most important and ubiquitous ideas. It is well known that the breakdown of global and continuous symmetry gives rise to gapless excitations called Nambu-Goldstone (NG) bosons. This is called NG theorem. Since the generators of broken symmetries are bosonic, the excitations are also bosons.

Electrical Manipulation of Field‐Free Magnetization Switching Driven by Spin‐Orbit Torque in Amorphous Gradient‐Mn3Sn

Advanced Science, EarlyView.
A highly efficient spin current with z‐polarization is achieved in amorphous Mn3Sn with a spontaneous composition gradient, which allows field‐free magnetization switching. Spin current efficiency and magnetization switching polarity are reversibly manipulated by ionic liquid gating, enabling logic functions by pure electrical methods. This work offers

Boron‐Based Functional Additives Enable Solid Electrolyte Interphase Engineering in Calcium Metal Battery

Batteries &Supercaps, Volume 6, Issue 1, January 2023., 2023
Engineering of Ca‐based SEI using boron‐based additives is investigated and their morphology, composition, and properties are thoroughly characterized. The presence of boron‐crosslinked polymeric matrices in the passivation layer plays a major role allowing for Ca plating.

Embedding cosmological inflation, axion dark matter and seesaw mechanism in a 3-3-1 gauge model

Physics Letters B, 2017
The Peccei–Quinn symmetry is an intrinsic global symmetry of the 3-3-1 gauge models. Its spontaneous breaking mechanism engendering an invisible KSVZ-like axion links the 3-3-1 models with new physics at ∼1010 GeV scale.

3D Printed Sodiophilic Reduced Graphene Oxide/Diamane Microlattice Aerogel for Enhanced Sodium Metal Battery Anodes

Advanced Science, EarlyView.
A 3D printed sodiophilic rGO/diamane microlattice aerogel with uniform ions flux and exceptional sodiophilic features is demonstrated as a stable host for sodium metal anode. The sodiophilic diamane nanoflakes regulate the uniform deposition of metallic Na with a dendrite‐free deposition morphology, achieving an ultra‐high areal capacity of 78.60 mAh ...
