Abstract Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons well nuclei. As a future high energy nuclear physics project, Electron-ion collider in China (EicC) has been proposed. It will be constructed based on upgraded heavy-ion accelerator, High Intensity Accelerator Facility (HIAF) which currently under construction, together with new electron ring. The proposed provide highly polarized electrons (with polarization ∼80%) and...
The Carroll group was originally introduced by Levy-Leblond [1] considering the limit of Poincar\'e as $c\to0$. In this paper an alternative definition, based on geometric properties a non-Minkowskian, non-Galilean but nevertheless boost-invariant, space-time structure is proposed. A "duality" with Galilean $c\to\infty$ established. Our theory illustrated Carrollian electromagnetism.
We give an account of the gravitational memory effect in presence exact plane wave solution Einstein's vacuum equations. This allows elementary but description soft gravitons and how their may be detected by observing motion freely falling particles. The theorem Bondi Pirani on caustics (for which we present a new proof) implies that asymptotic relative velocity is constant not zero, contradiction with permanent displacement claimed Zel'dovich Polnarev. A non-vanishing might used to detect...
The "gravitational memory effect" due to an exact plane wave provides us with elementary description of the diffeomorphisms associated soft gravitons. It is explained how presence latter may be detected by observing motion freely falling particles or other forms gravitational detection. Numerical calculations confirm relevance first, second and third time integrals Riemann tensor pointed out earlier. Solutions for various profiles are constructed. also shown extend our treatment...
We investigate the generalized second law of thermodynamics (GSL) in theories gravity. examine total entropy evolution with time including horizon entropy, non-equilibrium production, and all matter, field energy components. derive a universal condition to protect study its validity different gravity theories. In Einstein (even phantom-dominated universe Schwarzschild black hole), Lovelock braneworld gravity, we show that keep GSL can always be satisfied. f(R) scalar–tensor also hold because...
The well-known 5-parameter isometry group of plane gravitational waves in 4 dimensions is identified as Lévy-Leblond's Carroll with no rotations. Our clue that are Bargmann spaces into which manifolds can be embedded. We also comment on the scattering light by a wave and calculate its electric permittivity considered an impedance-matched metamaterial.
The problem of the position and spin in relativistic quantum mechanics is analyzed detail. It definitively shown that operators Foldy-Wouthuysen representation (but not Dirac one) are quantum-mechanical counterparts classical variables. probabilistic interpretation valid only for wave functions. discussed. spin-orbit interaction does exist a free particle if conventional orbital angular momentum rest-frame used. Alternative definitions based on noncommutative geometry, do satisfy standard...
The particle with first-order dynamics proposed by Dunne, Jackiw and Trugenberger (DJT) to justify the ``Peierls substitution" is obtained reduction from both of planar two-parameter centrally extended Galilean Carroll systems. In latter case extension parameters $\kappa_{exo}$ $\kappa_{mag}$ generate non-commutativity coordinates resp. behave as an internal magnetic field. position momentum follow uncoupled anomalous Hall motions. Consistently partial immobility, one boost generators broken...

Approximating the derivative-of-the-Gaussian profile proposed by Gibbons and Hawking scarf potential, scattering of particles a gravitational wave generated flyby is described analytically following Nikiforov-Uvarov method. Pure displacement arises when zone contains an integer number half-waves. The results confirm prediction Zel'dovich Polnarev.
Chiral fermions can be embedded into Souriau's massless spinning particle model by "enslaving" the spin, viewed as a gauge constraint. The latter is not invariant under Lorentz boosts; spin enslavement restored, however, subsequent Wigner-Souriau (WS) translation, analogous to compensating transformation. combined transformation precisely recently uncovered twisted boost, which we now extend finite transformations. WS-translations are identified with stability group of motion acting on right...
Circularly polarized gravitational sandwich waves exhibit, as do their linearly counterparts, the Velocity Memory Effect: freely falling test particles in flat after-zone fly apart along straight lines with constant velocity. In inside zone trajectories combine oscillatory and rotational motions a complicated way. For circularly periodic some remain bounded, while others spiral outward. These admit an additional "screw" isometry beyond usual five. The consequences of this extra symmetry are explored.
Due to their low flammability, good dimensional stability and chemical stability, solid polymer electrolytes are currently attracting extensive interest for building lithium metal batteries. But severe safety issues such as cracks or breakage, resulting in short circuits will prevent widespread application. Here, we report a new design of self-healing electrolyte (ShSPE) based on imine bonds, fabricated from varying amounts polyoxyethylenebis(amine) terephthalaldehyde through simple Schiff...
