Probing Planck-Scale Physics with Quantum Optics |
Speaker: | Igor Pikovski (Uni Wien) |
Abstract: | One of the main challenges in physics today is to merge quantum theory and the theory of general relativity into a unified framework. Various approaches towards developing such a theory of quantum gravity are pursued, but the lack of experimental evidence of quantum gravitational effects thus far is a major hindrance. Yet, the quantization of space-time itself can have experimental implications: the existence of a minimal length scale is widely expected to result in a modification of the Heisenberg uncertainty relation. Here we introduce a scheme that allows an experimental test of this conjecture by probing directly the canonical commutation relation of the center of mass mode of a massive mechanical oscillator with a mass close to the Planck mass. Our protocol utilizes quantum optical control and readout of the mechanical system to probe possible deviations from the quantum commutation |

Matrix models, branes and gravity |
Speaker: | Harold Steinacker |
Abstract: | An informal introduction to branes in Yang-Mills matrix model is given,
focusing on the IIB model. Aspects of the effective gauge theory, geometry and gravity on these branes are discussed, having in mind a brane-world scenario.
