Stability of Spacelike Hypersurfaces in Foliated Spacetimes [PDF]
arXiv, 2006 We show that a given $x:M^n\to \bar{M}^{n+1}=I\times_{\phi}F^{n}$ closed spacelike hypersurface with constant mean curvature $H$ and warping function $\phi$ satisfying \phi ''\geq \ma\{H\phi'',0\}$ is either minimal or a spacelike slice $\{t_{o}\}\times F$ for some $t_{o}\in I$.

Advanced Functional Materials, EarlyView.By integrating machine learning into flux‐regulated crystallization (FRC), accurate prediction of solvent evaporation rates in real time, improving crystallization control and reducing crystal growth variability by over threefold, is achieved. This enhances the reproducibility and quality of perovskite single crystals, leading to reproducible ...

Advanced Functional Materials, EarlyView.[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

Chiroferromagnetic Quantum Dots for Chiroptical Synapse (ChiropS)
Advanced Materials, EarlyView.Chiroptical activity is enhanced by up to 0.003 in the g‐factor through the induction of ferromagnetism in quantum dots. A chiroptical neuromorphic synapse, composed of chiroferromagnetic quantum dots, generates different synaptic weights from multiple wavelengths and circularly polarized light.

Spreading of wave packets, Uncertainty Relations and the de Broglie Frequency [PDF]
Apeiron 8, n1 (2001), 1998 The spreading of quantum mechanical wave packets is studied in two cases. Firstly we look at the time behavior of the packet width of a free particle confined in the observable Universe. Secondly, by imposing the conservation of the time average of the packet width of a particle driven by a harmonic oscillator potential, we find a zero-point energy ...
