Four-dimensional de Sitter space is a Glauber-Sudarshan state in string theory

Abstract We show that four-dimensional de Sitter space is a Glauber-Sudarshan state, i.e. a coherent state, over a supersymmetric solitonic background in full string theory. We argue that such a state is only realized in the presence of temporally varying degrees of freedom and after including quant...
