Quantization, Dequantization, and Distinguished States on causal sets and beyond
University of York
Abstract: In this talk I will discuss the results of the paper "Quantization, Dequantization, and Distinguished States" written in callaboration with Eli Hawkins and Christoph Minz. In this work we consider free quantum fields on a causal set and demonstrate how methods of geometric quantization can be applied in that case. We compare the result with the Sorkin-Johnson construction and demonstrate that both approaches single out the same quantum state.
