Variational Adaptive Gaussian Decomposition: Scalable Quadrature-Free Time-Sliced Thawed Gaussian Dynamics
Rahul Sharma, Amartya Bose
Time-slicing has emerged as a strategy for incorporating semiclassical propagation into real-time path integral formulation and recovering full quantum dynamics. A central step is…
Quantum-Classical Hierarchical Equations of Motion
Amartya Bose
We develop a quantum-classical hierarchical equations of motion (QC-HEOM) approach for simulating non-Markovian open quantum systems. The method combines the ensemble-averaged clas…
Path Integral Lindblad Dynamics in Presence of Time-Dependent Fields
Amartya Bose
The path integral Lindblad dynamics (PILD) method [A. Bose, J. Phys. Chem. Lett. 15(12), 3363-3368 (2024)] had been introduced as a way of incorporating the impact of certain empir…
Excitonic description of singlet fission beyond dimer model : a matrix product state approach
Supriyo Santra, Amartya Bose, Debashree Ghosh
The importance of singlet fission as a fundamental process with a variety of implications in energy harvesting cannot be overstated. The challenge is in characterizing the energy s…
