Fast, Accurate Simulation of Polaron Dynamics and Multidimensional Spectroscopy by Multiple Davydov Trial States.
TL;DR: For the first time, 2D spectra have been calculated for systems with off-diagonal exciton-phonon coupling by employing themultiple D2 ansatz to compute the nonlinear response function, testifying to the great potential of the multiple D1 (D2) ansatz for fast, accurate implementation of multidimensional spectroscopy.
Excitonic energy transfer in light-harvesting complexes in purple bacteria
TL;DR: In this paper, two distinct approaches, the Frenkel-Dirac time-dependent variation and the Haken-Strobl model, are adopted to study energy transfer dynamics in single-ring and double-ring light-harvesting systems in purple bacteria.
Monitoring of singlet fission via two-dimensional photon-echo and transient-absorption spectroscopy: Simulations by multiple Davydov trial states
TL;DR: Employing the Dirac-Frenkel time dependent variational method, the nonlinear spectra monitoring the singlet fission process mediated by a conical intersection of the two lowest excited electronic states are investigated for different optical dephasings.

Photon-assisted Landau-Zener transitions in a periodically driven Rabi dimer coupled to a dissipative mode
TL;DR: In this paper, the authors investigate multiple photon-assisted Landau-Zener (LZ) transitions in a hybrid circuit quantum electrodynamics device in which each of two interacting transmission-line resonators is coupled to a qubit, and the qubits are driven by periodic driving fields and also coupled with a common phonon mode.

Theoretical examination of long-range energy propagation in nano-engineered light-harvesting antenna arrays
TL;DR: In this paper, a biomimetic molecular nanoarray constructed from LH2 antenna complexes is investigated by a master equation approach including the effect of coherent hopping, and the time-dependent fluorescence intensity is derived using the same formalism.
