# Simulating chiral magnetic effect and anomalous transport phenomena in the pre-equilibrium stages of heavy-ion collisions

## TL;DR

This paper uses real-time lattice simulations to study the Chiral Magnetic Effect during the early stages of heavy-ion collisions, revealing how quark mass influences charge transport phenomena.

## Contribution

It introduces a first principles simulation framework to analyze chiral magnetic phenomena in pre-equilibrium heavy-ion collisions, incorporating dynamical fermions and electromagnetic interactions.

## Key findings

- Light quarks exhibit dissipation-less charge transport similar to anomalous hydrodynamics.
- Heavier quarks show reduced currents due to explicit chiral symmetry breaking.
- The approach provides insights into early-stage chiral effects in heavy-ion collisions.

## Abstract

We present a first principles approach to study the Chiral Magnetic Effect during the pre-equilibrium stage of a heavy-ion collision. We discuss the dynamics of the Chiral Magnetic Effect and Chiral Magnetic Wave based on real-time lattice simulations with dynamical (Wilson and Overlap) fermions simultaneously coupled to color and electromagnetic fields. While for light quarks we observe a dissipation-less transport of charges as in anomalous hydrodynamics, we demonstrate that for heavier quarks the effects of explicit chiral symmetry breaking lead to a significant reduction of the associated currents.
