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 study demonstrates that thermal boundary conductance at metal/semiconductor interfaces can be significantly enhanced, such as by 40% in n-doped silicon/titanium junctions, by applying an electric current to shrink the space charge area, thereby establishing a method to modulate interfacial heat transfer through electrical tuning.
This study derives closed-form analytical expressions for the first and second-order terms in an asymptotic expansion of skin temperature distribution under electromagnetic heating, thereby accurately capturing the significant effects of both incident angle and lateral heat conduction even at moderate length scale ratios where previous leading-term approximations were insufficient.
This paper derives new exact proportional and double Kerr-Schild solutions in multigravity by extending General Relativity results with constant Ricci scalars, while also investigating the associated classical double copy relations and their single and zero copy field dynamics.
This paper proposes a graph-based framework that leverages lobe dynamics within the circular restricted three-body problem to systematically design and optimize low-energy cislunar transfer trajectories, which are subsequently refined using the bicircular restricted four-body problem.
This paper proposes an alternative framework for classical mechanics that resolves ambiguities in Newton's formulation by integrating the ideas of Huygens, Leibniz, and Lange, demonstrating that this approach successfully rederives standard results for point masses and extends to relativistic particles.
This paper demonstrates that first-order phase transitions can manifest as either discontinuous or continuous phenomena depending on whether the number of extensive state variables is less than or greater than or equal to the number of coexisting phases, respectively.
This paper presents and validates a novel sharp-interface immersed boundary method integrated with the blastFOAM library on OpenFOAM, which effectively simulates high-speed compressible flows with complex and dynamic geometries by combining slip boundary conditions, polynomial reconstruction, and multiple flux schemes to achieve accurate shock resolution without requiring body-fitted meshes.
This paper proposes and substantiates a conjecture that the infinite symmetries of integrable systems are linear combinations of translation symmetries associated with the free parameters of multi-wave solutions, suggesting that undiscovered symmetries exist and that a unified hierarchical framework for classical, supersymmetric, and ren-symmetric integrable systems can be established using ren-variables.
This paper reviews the foundational theory of Brownian motion from Einstein and Langevin to modern stochastic thermodynamics and fluctuation theorems, while also analyzing non-Markovian dynamics through generalized Langevin equations to elucidate the fluctuation-dissipation relation and the effective-mass framework.
This paper presents a compact, dual-slot on-chip antenna operating at 290 GHz that achieves a maximum efficiency of 42% and a 39% impedance bandwidth on a low-resistivity silicon substrate, making it suitable for sub-terahertz transceivers and radar applications.
