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…
For molecular polaritons, disorder and phonon timescales control the activation of dark states in the thermodynamic limit
Tianchu Li, Pranay Venkatesh, Qiang Shi +1
Collective light-matter systems host an extensive manifold of dark states whose role in the emergence of thermodynamic behavior remains poorly understood, especially in the presenc…
Coherent and Dynamic Small Polaron Delocalization in CuFeO
Jocelyn L. Mendes, Srijan Bhattacharyya, Chengye Huang +10
Small polarons remain a significant bottleneck in the realization of efficient devices using transition metal oxides. Routes to engineer small polaron coupling to electronic states…
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…
