Temperature dependent nonlinear optics


Temperature dependent nonlinear optics

Our new work on “Temperature dependent nonlinear optics” is finally online. In this work we combine many-body perturbation theory for the electron-phonon coupling with real-time dynamics for the electrons in such a way to describe the temperature effects in the non-linear response. The preprint is available here: https://arxiv.org/abs/2609.07796v1

Lumen 2.1


Lumen 2.1

After 7 months from the first version of Lumen the 2.0 we release a new version the 2.1. This version fixes different bugs in compilation and executions but it also introduce different new features as non-linear response within the Floquet formalism or the symmetry analysis for the excitons. Release notes can be found here:https://www.lumen-code.org/wiki/index.php?title=Lumen_2.1 and… Read More
