Selfconsistent diagrammatic transport for light including time reversal symmetric entropy production — •Regine Frank^1,2 and Bart A. van Tiggelen³ — ¹College of Biomedical Sciences, Larkin University, Miami, Florida, USA — ²Donostia International Physics Center, 20018 Donostia-San Sebastian, Spain — ³University Grenoble Alpes, Centre National de la Recherche Scientifique, LPMMC, Grenoble, France

We present novel theory and numerics for transport of light in random complex media, where the production of entropy is positive under time reversal, an Onsager scenario. Numerical solutions based on weighted essentially non-oscillatory solvers (WENO) are introduced. Anderson localization is quantitatively discussed.
