Continuous Representation Theory of the Hierarchical Equations of Motion
Tianchu Li, Pranay Venkatesh, Andrés Montoya-Castillo
The numerical stability of the hierarchical equations of motion (HEOM) depends on the representation of their Liouvillian. Here, we introduce a continuous gauge freedom through a g…
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…
Development and Evaluation of a Narrow Linewidth Laser System for 171Yb+ E2 Transition
Yani Zuo, Shiying Cao, Shaoyang Dai +9
We report the construction and characterization of a narrow-linewidth laser system to interrogate the E2 clock transitions at 436 nm of ytterbium ions trapped in end-cap traps. The…
