Femtosecond nonlinear spectroscopy is the main tool for the time-resolved detection of
photophysical and photochemical processes. Since most systems of chemical interest are …

Due to the subtle interplay of site-to-site electronic couplings, exciton delocalization,
nonadiabatic effects, and vibronic couplings, quantum dynamical studies are needed to …

This Perspective presents an overview of the development of the hierarchy of Davydov's
Ansätze and a few of their applications in many-body problems in computational chemical …

The eigenstate thermalization hypothesis (ETH) is a successful theory that provides
sufficient criteria for ergodicity in quantum many-body systems. Most studies were carried …

By employing the time-dependent variational principle and the versatile multi-D 2 Davydov
trial states, in combination with the Green's function method, we study the dynamics of the …

This review provides a bird's eye view over the development of the hierarchy of Davydov's
Ansätze and its applications in a variety of problems in computational physical chemistry …

The twin-formulation of quantum statistical mechanics is employed to describe a new
methodology for the solution of the equations of motion of the reduced density matrix in their …

Transient localization has been proposed as a transport mechanism in organic materials, for
both charge carriers and excitons. Here, we characterize a quantum coherent transient …

The photosynthetic apparatus of plants and bacteria combine atomically precise pigment–
protein complexes with dynamic membrane architectures to control energy transfer on the …

In this paper, we present dyadic adaptive HOPS (DadHOPS), a new method for calculating
linear absorption spectra for large molecular aggregates. This method combines the …
