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…
Streamlining Analysis and Design of Two-Dimensional Electronic Spectroscopy using Machine Learning
Nicholas I. Hausman, Joseph Kelly, Michael S. Chen +5
Two-dimensional electronic spectroscopy (2DES) offers unique insights into the coupling between electronic and nuclear motion and dynamics, making it a key technique in diverse fie…
Numerically exact quantum dynamics with tensor networks: Predicting the decoherence of interacting spin systems
Tianchu Li, Pranay Venkatesh, Nanako Shitara +1
Predicting the quantum dynamics of promising solid-state and molecular quantum technology candidates remains a formidable challenge. Yet, accessing these dynamics is key to underst…
Nonequilibrium relaxation exponentially delays the onset of quantum diffusion
Srijan Bhattacharyya, Thomas Sayer, Andrés Montoya-Castillo
Predicting the exact many-body quantum dynamics of polarons in materials with strong carrier-phonon interactions presents a fundamental challenge, often necessitating one to adopt…
