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. The primordial seeds to all structures in the universe could in fact have been provided by tiny primordial quantum fluctuations of the spacetime. Thus studying such quantum fluctuations we can understand what kind of processes happened in the early universe and why our universe looks like it does and not something completely different.

Do you have a favourite figure from a paper you authored?

aus „No-Boundary Proposal as a Path Integral with Robin Boundary Conditions“ (Phys. Rev. Lett. 122, 201302)

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).
