Quantum dynamics in the self-consistent quadratic approximation

Autor: Rodriguez, Frank Ernesto Quintela

A self-consistent quadratic theory is presented to account for nonlinear contributions in quantum dynamics. Evolution equations are shown to depend on higher-order gradients of the Hamiltonian, which are incorporated via their equations of motion or

Vibrational response functions for multidimensional electronic spectroscopy: from Duschinsky rotations to multimode squeezed coherent states

Autor: Rodriguez, Frank Ernesto Quintela, Troiani, Filippo

Publikováno v: J. Chem. Phys. 159, 084111 (2023)

Multidimensional spectroscopy unveils the interplay of nuclear and electronic dynamics, which characterizes the ultrafast dynamics of various molecular and solid-state systems. In a class of models widely used for the simulation of such dynamics, fie

Vibrational response functions for multidimensional electronic spectroscopy in the adiabatic regime: a coherent-state approach

Autor: Rodriguez, Frank Ernesto Quintela, Troiani, Filippo

Publikováno v: J. Chem. Phys. 157, 034107 (2022)

Multi-dimensional spectroscopy represents a particularly insightful tool for investigating the interplay of nuclear and electronic dynamics, which plays an important role in a number of photophysical processes and photochemical reactions. Here we pre
