Exact formula with two dynamically screened electron-phonon couplings for positive phonon-linewidths approximations
Dr. Stefanucci and Dr. Perfetto from University of Rome Tor Vergata as members of the TIMES Project introduced an exact formula for the phonon linewidths involving only dressed electron-phonon couplings and ensuring the positivity property.

Excitonic Bloch equations from first principles
Dr. Stefanucci and Dr. Perfetto from University of Rome Tor Vergata as members of the TIMES Project published new excitonic Bloch equations. The introduction of an auxiliary exciton species, termed the irreducible exciton, enables to formulate a close set of equations describing exciton dynamics without unphysical overscreening.

TIMES partner published a theory of coherent phonons coupled to excitons
Last June, 2024, Dr. Perfetto, a researcher at the University of Rome Tor Vergata and member of the TIMES Project, published together with his colleagues Dr. Wu and Dr. Stefanucci a quantum many-body theory for the effective interaction between excitons and coherent phonons. This theory predicts that the exciton energy features a polaronic-like red-shift and…

UV leads times project to generate highly qualified PhD in subjects of priority interest to the EU
Marie Skłodowska-Curie Actions of the European Commission fund the development of excellent doctoral and postdoctoral training programmes and collaborative research projects worldwide. The TIMES doctoral network will train a new generation of scientists capable of devising new theoretical and computational frameworks to simulate non-equilibrium phenomena, such as those occurring in solar cells when light generates…
