Hidden Gauge Freedom in Complex-Pole Hierarchical Equations of Motion
Tianchu Li, Andrés Montoya-Castillo
While complex-pole hierarchical equations of motion (HEOM) have dramatically expanded the reach of numerically exact quantum dynamics simulations of open quantum systems, they suff…

Is there a finite mobility for the one vibrational mode Holstein model? Implications from real time simulations
Tianchu Li, Yaming Yan, Qiang shi
The question of whether there exists a finite mobility in the standard Holstein model with one vibrational mode on each site remains unclear. In this letter, we approach this probl…
