A numerical calculation of the electric conductivity of a hadron gas is presented using the hadronic transport approach SMASH (Simulating Many Accelerated Strongly-interacting Hadrons).
Transport coefficients are important properties of matter and a necessary input for dissipative fluid dynamics. They can be calculated analytically for a simplified setup e.g a pion gas. For more realistic systems like a full hadronic gas, it is only feasible to calculate the electric conductivity numerically.
As a first step towards the calculation of the electric conductivity of a full hadronic gas, a pion box with periodic boundary conditions is initialized within SMASH and extract the electric conductivity with the Green-Kubo formalism to compare it to previous results.
