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 predicts and experimentally demonstrates a unique flat-band skin effect in non-Hermitian systems, where the phenomenon arises from the spectral topology of surrounding dispersive bands rather than the flat band itself, exhibiting a counterintuitive disappearance at high non-Hermiticity and singular gap-closing behavior at exceptional points.
This paper identifies and characterizes "eversion buckling" in toroidal shells as a pitchfork-type bifurcation mechanism that enables the design of omnidirectional, high-efficiency energy-absorbing granular systems with stable stress plateaus.
This paper presents an exact analytical solution for electron dynamics in a plane electromagnetic wave by incorporating a Gaunt-factor-modified quantum radiation reaction into the Landau-Lifshitz equation, demonstrating that the system retains its classical integrability and yields a deterministic description of semiclassical energy evolution.
This paper introduces a procedure for thermodynamical verification that establishes internal settings to ensure constitutive equations are consistent with both energy and entropy balances by accounting for the interdependence of heat flux, entropy flux, and their time differentials.
This paper proposes a Lagrangian extension to Newtonian gravity involving a second dynamical scalar field, derives its post-Newtonian potential and N-body equations, and constrains the model's free parameter using observational data from the Nordtvedt effect and Mercury's perihelion shift.
This paper demonstrates through nanometer-resolution experiments and theoretical modeling that static friction is not an intrinsic material property but an emergent phenomenon arising from the collective configurational evolution of surface asperities, which generates a friction overshoot as the system transitions toward a steady-state kinetic friction.
This paper demonstrates how to model a beer bottle's acoustical resonance as a one-dimensional driven-damped oscillator and proposes using Fourier methods to efficiently collect the necessary data for parameter fitting in undergraduate laboratory experiments.
This paper proposes a framework that extends Equilibrium Propagation to arbitrary non-conservative systems by modifying the learning-phase dynamics to account for non-reciprocal interactions, thereby enabling the exact computation of cost function gradients and achieving superior performance compared to previous methods.
This paper resolves the long-standing controversy over relativistic temperature transformations by demonstrating that effective temperature increases with velocity in a manner dependent on the system's equation of state, thereby supporting the Ott-Eddington interpretation and establishing temperature as an observer-dependent quantity linked to the inverse-temperature four-vector.
This study introduces a novel theoretical framework for electromagnetic superlensing that clarifies the resolution potential of complex-frequency and pulse illuminations while revealing intrinsic limitations that temper the high expectations raised by recent infrared experiments.
