NESSi 2.0: The Non-Equilibrium Systems Simulation package version 2.0
NESSi 2.0 extends quantum many-body simulation by incorporating memory truncation of Kadanoff-Baym equations and explicit Nonequilibrium Steady State (NESS) functionalities. This addresses severe computational bottlenecks in long-time simulations, allowing researchers to study complex transport phenomena and prethermal states with reduced complexity while maintaining high accuracy.
