Discretization of Structured Bosonic Environments at Finite Temperature by Interpolative Decomposition: Theory and Application
Hideaki Takahashi, Raffaele Borrelli
We present a comprehensive theory for a novel method to discretize the spectral density of a bosonic heat bath, as introduced in [H. Takahashi and R. Borrelli, J. Chem. Phys. \text…

Nonadiabatic Quantum Dynamics of Molecules Scattering from Metal Surfaces
Riley J. Preston, Yaling Ke, Samuel L. Rudge +4
Nonadiabatic coupling between electrons and molecular motion at metal surfaces leads to energy dissipation and dynamical steering effects during chemical surface dynamics. We prese…

Finite temperature dynamics in a polarized sub-Ohmic heat bath: a hierarchical equations of motion-tensor train study
Hideaki Takahashi, Raffaele Borrelli, Maxim F. Gelin +1
Dynamics of the sub-Ohmic spin-boson model under polarized initial conditions at finite temperature is investigated by employing both analytical tools and the numerically accurate…
