Charged Weyssenhoff fluid spheres in Einstein–Cartan–Maxwell theory: a general algorithm
European Physical Journal C: Particles and FieldsWe construct exact static, spherically symmetric charged fluid solutions within the framework of Einstein–Cartan–Maxwell (ECM) theory, in which intrinsic spin and spacetime torsion are incorporated through the Weyssenhoff spin fluid.

Advanced Materials, EarlyView.We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Harmonicity and minimality of distributions on Riemannian manifolds via the intrinsic torsion
Revista Matemática Iberoamericana, 2014 We consider a q -dimensional distribution as a section of the Grassmannian bundle G_{q}(M^{n}) of q -planes and we derive, in terms of the intrinsic torsion of the corresponding

Advanced Materials, EarlyView.Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions
Advanced Materials, EarlyView.Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

A review of Einstein Cartan Theory to describe superstrings with intrinsic torsion
, 2020 This paper reviews the Einstein Cartan theory (ECT), the famous extension of general relativity (GR) in presence of spacetime torsion. The vacuum equations are derived step by step. Vielbein formulation is discussed for determining the field equations in presence of matter.

Advanced Materials, EarlyView.ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...
