Uncertainty Relation and Micro Black Holes in a Planck Scale Lattice Universe

Abstract: We study a model of the universe with crystal-like structure and lattice spacing of about the Planck length, and in this universe we formulate a generalized uncertainty relation. We then apply our results to micro black hole physics, and derive a modified temperature for Hawking radiation. Our temperature formula predicts both a finite temperature and a zero
mass at the end of the micro black hole evaporation. We also briefly mention a few other connections, in particular with a possible modification of special relativity.

Bio: Fabio Scardigli earned his PhD studying General Relativity at the Institute for Theoretical Physics-Bern (ITP) with Petr Hajicek. He was a postdoc fellow at the Center for Relativistic Astrophysics (CENTRA), Instituto Superior Tecnico in Lisbon ,where he studied with Jose' Lemos. Dr. Scardigli was also a fellow at the Japan Society for the Promotion of Science (JSPS), Yukawa Institute,Kyoto, where he studied with Misao Sasaki. He is currently a Distinguished Assistant Fellow at Leung Center for Cosmology and Particle Astrophysics (LeCosPA) National Taiwan University, Tapei ,where he is working with Pisin Chen.
