Probability distribution for the quantum universe
Alex Kehagias, Hervé Partouche, Nicolaos Toumbas
We determine the inner product on the Hilbert space of wavefunctions of the universe by imposing the Hermiticity of the quantum Hamiltonian in the context of the minisuperspace mod…
Geometry of orientifold vacua and supersymmetry breaking
Thibaut Coudarchet, Emilian Dudas, Hervé Partouche
Starting from a peculiar orientifold projection proposed long ago by Angelantonj and Cardella, we elaborate on a novel perturbative scenario that involves only D-branes, together w…
Gauge fixing and field redefinitions of the Hartle--Hawking wavefunction path integral
Hervé Partouche, Nicolaos Toumbas, Balthazar de Vaulchier
We review some recent results concerning the Hartle--Hawking wavefunction of the universe. We focus on pure Einstein theory of gravity in the presence of a positive cosmological co…
Wavefunction of the universe: Reparametrization invariance and field redefinitions of the minisuperspace path integral
Hervé Partouche, Nicolaos Toumbas, Balthazar de Vaulchier
We consider the Hartle-Hawking wavefunction of the universe defined as a Euclidean path integral that satisfies the "no-boundary proposal." We focus on the simplest minisuperspace…
