Jerzy Lewandowski
Jerzy Lewandowski is a Polish theoretical physicist who studies quantum gravity . He is a professor at the University of Warsaw .
Lewandowski received his doctorate in Warsaw under Andrzej Trautman . He worked closely in the 1990s with Abhay Ashtekar at the Pennsylvania State University in the mathematical justification of loop quantum gravity (Loop Quantum Gravity, LQG) together. Among other things, he was at the Erwin Schrödinger Institute in Vienna and at the Max Planck Institute for Gravitational Physics in Golm near Potsdam.
He dealt with cosmological models and the entropy of black holes in the LQG. In 2010 he and his colleagues investigated a scalar field together with the gravitational field within the framework of the LQG and was able to show the emergence of a time as the ratio of the scalar to the gravitational field and the quantization of the gravitational field.
