主讲人简介：Kristina Giesel has been a professor at the Institute for Quantum Gravity at the Friedrich-Alexander Universität Erlangen-Nürnberg since 2011. She was previously an Assistant Professor at Louisiana State University in Baton Rouge and held postdoctoral positions at the Albert Einstein Institute, Max Planck Institute for Gravitational Physics in Postdam, the Nordic Institute for Theoretical Physics (Nordita) in Stockholm and the Excellence Cluster Universe at LMU in Munich. In 2025, she was awarded a Simons Emmy Noether Fellowship from the Perimeter Institute for Theoretical Physics in Waterloo. Her research field is quantum gravity, with a particular focus on the dynamics including the formulation of the Quantum Einstein Equations in loop quantum gravity and with applications to cosmology and black holes. This also includes the role and properties of (quantum) reference frames in this context. In addition, she has recently started to investigate open quantum systems including gravity and gravitationally induced decoherence with applications in the context of neutrino oscillations.
报告题目：The Quantum Einstein Equations of Loop Quantum Gravity
报告摘要：Loop quantum gravity is a candidate for a theory of quantum gravity that takes general relativity as its classical starting point. In the canonical approach, the quantum theory is obtained by applying a canonical quantization to general relativity. To this end, the techniques known from quantum field theory, which are used in the standard model of particle physics, need to be generalized in order to apply them to general relativity, in which the geometry of spacetime is a dynamical quantity. The dynamics of the quantum theory is described by the so-called Quantum Einstein equations, the quantum analog of Einstein's equations. After a brief introduction to the ideas and concepts of loop quantum gravity, we will discuss recent applications of loop quantum gravity in the context of cosmology and black holes.
