Gravity Generated by Motion: g = k·v Model and Orbital Simulation Open
This work proposes a motion-based model of gravity where gravitational acceleration is not determined by mass alone but emerges as a consequence of motion. If an object is motionless (v=0), gravity becomes zero; as velocity increases, grav…

Research on LSTM space target orbit prediction based on attention mechanism enhancement Open
To address the problem that orbit prediction for space targets is highly dependent on physical models and initial conditions, and errors cannot be completely eliminated, a satellite orbit prediction and correction method is proposed that i…

Chiral-phonon generation of orbital currents in light transition metals Open
Orbital angular momentum offers a new channel for information transport in a vast set of materials. Its coherent generation and detection remain, however, largely unexplored. Here, we demonstrate that chiral surface acoustic waves (SAWs) g…

Relationship between Poincaré Sections and Spectral Characteristics of Orbits of Globular Clusters in the Central Region of the Galaxy Open
In the paper, orbital dynamics, regular or chaotic, of globular clusters (GCs) in the central region of the Galaxy, which is subject to the greatest influence of the rotating bar, has been studied. Such methods for determining chaos as Poi…

The shape-velocity alignment of satellites forged by tidal locking and dynamical friction Open
Utilizing the TNG50 simulation, we study two types of alignments for satellites/subhalos: 1) the alignment of their major axes with the galactocentric radial directions (radial alignment), and 2) with the motion directions (orbital alignme…

Evidence for strong localization of orbital polarization Open
Whether orbital polarization propagates has become the most essential question of the blooming orbitronics that aims to generate non-local orbital torque and orbital pumping. Recent theories have suggested a strong orbital Hall effect with…
