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 investigates the interaction of strong electromagnetic waves with unmagnetized pair plasmas, demonstrating that the process is governed by a single nonlinearity parameter which determines whether the wave acts as a relativistic piston driving a shock, with implications for neutron star radio pulses and future laser experiments.
This paper introduces a computationally efficient method for identifying bound states in the continuum (BICs) by analyzing their insensitivity to external boundary conditions through spectral histograms, offering a robust alternative to traditional quasi-normal mode analysis that avoids calculating complex eigenvalues.
This paper presents an elementary deduction of Newtonian force from Kepler's laws by generalizing Keplerian motion to non-Euclidean spaces with homogeneous functions, thereby revealing new convexity properties of orbits and describing their generalized hodographs.
This paper reports the experimental observation of two distinct Berry phases ( and ) on a triangular Möbius microwave resonator, where the phases arise specifically from resonant modes lacking rotational symmetry and are confirmed via frequency shifts compared to mirror-symmetric counterparts.
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 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 introduces a non-Hermitian causal generative model that produces statistically significant temporal correlations invisible to conventional spectral analysis, providing experimentally verified signatures of causal memory in open quantum systems.
This paper investigates electron dynamics in electromagnetic fields beyond the adiabatic approximation using Stormer theory, characterizing the spectrum of orbits as predominantly chaotic or hyperchaotic while highlighting unresolved questions regarding their impact on neutrino mass limits and correlation experiments.
This paper generalizes the construction of fracton models to phase space by classifying systems with multipole conservation laws and analyzing a new self-dual model that exhibits quasi-periodic orbits, thereby preventing full ergodic exploration of the phase space.
