Abstract
In this talk I'll discuss how and why a four-dimensional de Sitter space can only exist as an excited state and not as a vacuum state in string theory. This excited state differs from the usual coherent state and is called the Glauber-Sudarshan state.
Reading suggestion: It might be useful to read sec 8.1 of our recent paper 2404.11680.
