Organisms of all domains of life use photoreceptor proteins to sense and respond to light.
The light-sensitivity of photoreceptor proteins arises from bound chromophores such as …

Ultrafast processes in light-absorbing proteins have been implicated in the primary step in
the light-to-energy conversion and the initialization of photoresponsive biological functions …

Vitamin A (all-trans-retinol, 1, Figure 1) is considered the most multifunctional vitamin in the
human body. 1 It plays key roles in many physiological processes such as vision …

This roadmap article highlights recent advances, challenges and future prospects in studies
of the dynamics of molecules and clusters in the gas phase. It comprises nineteen …

The Dalton Project provides a uniform platform access to the underlying full-fledged
quantum chemistry codes Dalton and LSDalton as well as the PyFraME package for …

Microbial rhodopsins are photoreceptive membrane proteins that transport various ions
using light energy. While they are widely used in optogenetics to optically control neuronal …

The chromophores of rhodopsins (Rh) and light-harvesting (LH) complexes still represent a
major challenge for a quantum chemical description due to their size and complex electronic …

The excited states of the three retinal proteins, bovine rhodopsin (Rh), bacteriorhodopsin
(bR), and sensory rhodopsin II (sRII) were studied using the symmetry-adapted cluster …

The retinal protonated Schiff-base (RPSB) in its all-trans form is found in bacterial
rhodopsins, whereas visual rhodopsin proteins host 11-cis RPSB. In both cases …

First-principle many-body Green's function theory (MBGFT) has been successfully used to
describe electronic excitations in many materials, from bulk crystals to nanoparticles. Here …
