PhD student Lehel Csillag from Doctoral School of Physics, supervised by Prof. dr. Ladislau Nagy, presented a poster, together with a short talk (15minutes) at the spring school: Searching for quantum gravity in the sky, Bad Honnef, Germany. The main topic of the school was about experimental evidence of modified dispersion relations, signs of effective descriptions of quantum gravity. His poster about the Yano-Schrödinger hyperfluid fits into the picture, as its field equations contain modifications on the large scale to general relativity.
