This collection explores the fascinating world of physics, specifically focusing on theories and experiments ranging from acoustics to the physics of open quantum systems. Here, you will find groundbreaking research that helps us understand how sound travels, how light interacts with matter, and the fundamental forces shaping our universe, all explained without dense academic barriers.
At Gist.Science, we process every new preprint in this category directly from arXiv to ensure you have immediate access to the latest discoveries. For each paper, we provide both a clear, plain-language explanation for curious minds and a detailed technical summary for researchers, bridging the gap between complex data and human understanding.
Below are the most recent physics papers from Ao to Ph, freshly processed and ready for you to explore.
This paper proposes that the observed damping of Earth's nutations is fully explained by energy dissipation from tidal flows interacting with kilometer-scale topography at the core-mantle boundary, offering a more complete solution than previously considered electromagnetic coupling mechanisms.
This paper documents the calibration of the kilometer-scale global atmospheric model ARP-GEM2 and demonstrates that, at resolutions up to 2.6 km, parameterized convection remains essential for accurately representing the mean state while a balance must be struck between mean state fidelity and climate variability, suggesting that even higher resolutions may be required to fully realize the benefits of explicit convection.
This paper develops and experimentally validates a statistical theory explaining how islands in random two-dimensional wavefields, particularly under the influence of the Coriolis effect, dramatically enhance the formation of high-probability, high-intensity vortices, thereby elucidating the mechanism behind tidal vortices observed around oceanic islands.
This paper presents a century-long, global climate simulation at 2.6 km resolution using the ARP-GEM model, demonstrating the feasibility of kilometer-scale modeling to better represent fine-scale phenomena and support climate services for France's dispersed overseas territories, despite current limitations regarding prescribed sea surface temperatures.
This paper presents a data-driven methodology using the Koopman operator to analyze metastability in stochastic bistable systems by tracking subdominant modes to accurately predict escape statistics, reconstruct basins of attraction, and characterize multi-scale dynamics in both equilibrium and nonequilibrium conditions without relying on trajectory following.
This paper introduces a finite-memory multiplicative reversion process to demonstrate that high PM2.5 pollution regimes exhibit dynamical criticality characterized by reduced resilience and critical slowing down, revealing that recovery capacity varies significantly across regions and serves as a crucial complementary dimension to concentration-based air-quality assessment.
Satellite observations from 2019–2023 reveal that methane emissions from four major US landfills are on average six times higher than official EPA reports and are increasing, suggesting that the reported national decline in landfill emissions is an artifact of reporting methodologies rather than a genuine reduction.
This paper demonstrates that shortwave infrared imaging spectroscopy, utilizing reflected sunlight rather than thermal emission, can effectively quantify atmospheric ammonia emissions from industrial sources, as validated by Tanager-1 satellite data from Pakistan and Uzbekistan.
This paper reports the direct observation of Wilsonian runaway electrons in thunderstorms at Aragats, demonstrating that such detection is only possible when the acceleration region is within tens of meters of the detector under specific meteorological conditions, thereby explaining the century-long rarity of these observations.
This paper reports the first time-resolved observations of intense positron fluxes during thunderstorms at the Aragats Observatory, introducing a dual dipole electrodynamic model to explain how localized positron acceleration occurs alongside traditional electron-driven Thunderstorm Ground Enhancements.
