IAS Amplitudes Group Meeting
The No-Boundary Density Matrix
Abstract: Based on a recent paper with Juan and Yue-Zhou (https://arxiv.org/pdf/2409.14218). In this talk I will first review the no-boundary wavefunction in the context of inflation, and explain its natural generalization to the density matrix of a subregion. I will then illustrate it in a couple of examples, and explain properties and issues with this density matrix. If time permits, I will discuss how bubble nucleation saddles contribute to this state.
