Research Focus: Non-Markovian Memory Effects in Molecular Dynamics with Electronic Friction

Xuexun’s research explores how memory effects—where the system’s evolution depends on its past history—influence molecular dynamics on metal surfaces. Traditional electronic friction models often assume Markovian behavior (no memory), but real systems can exhibit more complex dynamics where past states influence current behavior.

Research Significance

Understanding non-Markovian effects is crucial for accurately modeling:

• Molecular motion on metal surfaces
• Energy dissipation mechanisms
• Surface chemical reactions
• Catalytic processes

By developing methods that properly account for memory effects, Xuexun’s work contributes to more accurate simulations of surface chemistry and dynamics.
