CASUS Institute Seminar, Dr. Jan Novák, Czech Technical University, Faculty of Mechanical Engineering, Department of Physics
Jan received his PhD in physics at the Charles University of Prague in 2015. His interests include the phenomenology of quantum gravity, gravitational waves from the early universe and mathematical physics.
Abstract of the talk // One of the biggest open problems in cosmology is to find a model of the accelerated expansion of the Universe in the last five billion years. There were trials to investigate it classically by adding some other fluid, modifying the field equations of general relativity, or using extra-dimensional models. But one can also utilize quantum gravity. Therefore, Jan and his colleagues formulated a new approach to the quantization of gravity, which they call the ring paradigm. Graviton is not a real particle, but it emerges as a vibration of a grid of rings that are new phenomenological objects. This has an immediate consequence for the resolution of the dark energy problem, and Jan and his team obtain a new model of the accelerated expansion. In this seminar, Jan will also explain an application of his results to classical cosmological models with a scalar field.
Jan will be talking live in Görlitz. However, as the event is organized in a hybrid format that includes a videoconferencing tool by Zoom Inc., people interested in the topic have the chance to also join the talk remotely. Please ask for the login details via email@example.com.
