This collection explores the fundamental physics concepts that govern how matter and energy interact across the universe. From the invisible forces shaping our daily lives to the complex mechanics driving cosmic phenomena, these studies reveal the underlying rules of reality. Here, we translate cutting-edge research into insights anyone can understand, bridging the gap between abstract theory and tangible discovery.
Every new preprint in this category originates from arXiv, where researchers first share their latest findings with the global community. At Gist.Science, we process each of these submissions to provide both detailed technical summaries and clear, plain-language explanations. This dual approach ensures that whether you are a seasoned physicist or a curious learner, you can grasp the significance of every breakthrough without getting lost in dense equations.
Below are the latest papers in Class-Ph, freshly processed and ready for you to explore.
This paper theoretically demonstrates that spatially varying oscillating magnetic fields induce eddy currents in non-magnetic conducting particles, generating steady forces and torques that drive magnetophoresis and amplify concentration fluctuations through anisotropic diffusion.
This paper develops a theoretical framework for Taylor dispersion in a soft, axisymmetric channel with Winkler-type compliant walls, demonstrating that wall softness significantly enhances both the effective advection velocity and the dispersion coefficient for solute transport under steady and pulsatile flow conditions.
This paper demonstrates that superpositions of toroidal electromagnetic pulses propagating in free space naturally generate localized regions where , thereby producing a co-propagating, space-time localized pseudoscalar field within the framework of axion electrodynamics, distinct from the physical creation of axion particles.
This paper presents concise analytical expressions and existence criteria for higher-order topological corner, edge, and bulk states in two-dimensional continuum grid-like frames, demonstrating their robustness and enabling direct engineering applications despite complex spectral overlaps.
This paper reviews, critiques, and extends analytical and numerical results on the equilibrium shapes of closed-loop catenaries (string shooters) by analyzing the bifurcations and vertical-orientation challenges inherent in closing such loops under gravity and drag, while relating these findings to similar systems like lariats and heavy elastica.
This paper utilizes molecular dynamics simulations of a harmonic lattice to reveal the complex thermalization process, highlighting distinct relaxation rates for velocity components, power-law frequency proliferation, concurrent defect generation, and two-stage out-of-plane fluctuation behaviors driven by broken symmetry.
This paper derives an analytical solution for the Strukov memristor model using basic algebra and calculus, and presents Lissajous figures illustrating its current response to a sinusoidal voltage.
This paper reinterprets the Hamilton-Jacobi equation as a model reduction that eliminates velocity degrees of freedom, thereby extending its applicability to general Newtonian systems with non-conservative forces and deriving a dissipative Schrödinger equation through a geometric optics approximation.
This paper develops and experimentally validates a comprehensive time-bandwidth framework for non-classically damped, linear two-degree-of-freedom systems with closely spaced modes, elucidating how strong modal interactions influence energy decay and frequency dispersion beyond the traditional unity limit.
This study utilizes numerical simulations to demonstrate that appropriately sized smoke curtains in ventilated tunnels significantly reduce the longitudinal air velocity required to contain fire smoke, despite the local thickening of the smoke layer caused by curtain-induced vortices.
