    Particlization with local event-by-event conservation laws

    Dmytro Oliinychenko🇺🇸 · Volker Koch🇺🇸

    We present a sampling method for the transition from relativistic hydrodynamics to particle transport, commonly referred to as particlization, which preserves the local event-by-event conservation of energy, momentum, baryon number, strangeness, and electric charge. The proposed method is essential for studying fluctuations and correlations by means of stochastic hydrodynamics. It is also useful for studying small systems. The method is based on Metropolis sampling applied to particles within distinct patches of the hypersurface, where hydrodynamics and kinetic evolutions are matched.

    Fredholm Method for Podolsky Quantum Wave Function

    Pedro Henrique Sales Girotto🇧🇷 · Jorge Henrique Sales🇧🇷

    In this paper we used the Fredholm method in Schroedinger's integral equation in the investigation of the scattering effect near the center of it between a stationary quantum wave function and an electrostatic potential. Two potentials are studied one Coulombian and the other Podolsky. The result shows the importance of the proposal of Podolsky to regularize the effect near the scattering center in the quantum wave function. Being that the coulombian potential presents with strong variation in the amplitude of the wave after the scattering. In the case of Podolsky's potential, this is corrected by adopting a constant that removes this strong variation.
