Alice Di Tucci
PhD student in the independent research group “Theoretical Cosmology"
What is your current position at our institute?
I'm a 3rd year PhD student in the Theoretical Cosmology group.
What is your academic education?
- BSc in physics (Università La Sapienza, Roma, Italy)
- MSc in theoretical physics (Università La Sapienza, Roma, Italy)
- on-going PhD in Mathematical and Physical aspects of Gravitation, Cosmology and Quantum Field Theory at the AEI
Can you please describe your research?
My research deals with quantum effects in the early universe and the role they play in setting the initial conditions of the universe. In this semiclassical approach one tries to go one step beyond the framework of quantum field theory in curved space time giving quantum properties to the background universe. This is achieved by means of gravitational path integrals i.e. sums over geometries in the saddle point approximation.
Do you have a favourite figure from a paper you authored?
This figure is from our paper The No-Boundary Proposal as a Path Integral with Robin Boundary Conditions. There, we rewrite Hartle’s and Hawking’s no-boundary wave function as a path integral with Robin boundary conditions: On the left we have the smooth saddle point geometry of the Harte-Hawking type. By contrast, with Robin boundary conditions a typical off-shell geometry will not start at zero size (middle). Some off-shell geometries contain a recollapse to zero size and it is these geometries that we avoid summing over (right).
