Insensitivity points and performance of open quantum interferometers under number-conserving & non-conserving Lindblad dynamics
Tommaso Favalli, Žan Kokalj, Andrea Trombettoni
We investigate the phase sensitivity of a linear two-mode atom interferometer subject to environmental noise, modeled within the framework of open quantum systems with both number-…
On the Emergence of Time and Space in Closed Quantum Systems
Tommaso Favalli
Time, space and entanglement are the main characters in this work. Their nature is still a great mystery in physics and we study here the possibility that these three phenomena are…
Effect of Energy Extensivity on the Performance of Open Quantum Interferometers
Žan Kokalj, Tommaso Favalli, Andrea Trombettoni
Studying the performance of a quantum interferometer coupled to an external environment is a problem of conceptual and practical importance. If we consider a quantum interferometer…
Quantum spacetime from constraints: wave equations and fields
Tommaso Favalli
In previous works, we showed that both time and space can emerge from entanglement within a globally constrained quantum Universe, with no background coordinates. By extending the…
Relativistic limits on the discretization and temporal resolution of a quantum clock
Tommaso Favalli
We provide a brief discussion regarding relativistic limits on the discretization and temporal resolution of time values in a quantum clock. Our clock is characterized by a time ob…
Time dilation of quantum clocks in a relativistic gravitational potential
Tommaso Favalli, Augusto Smerzi
We study the dynamical evolution of two quantum clocks interacting with a relativistic gravitational potential. We find a time dilation effect for the clocks in agreement with the…
A model of quantum spacetime
Tommaso Favalli, Augusto Smerzi
We consider a global quantum system (the "Universe") satisfying a double constraint, both on total energy and total momentum. Generalizing the Page and Wootters quantum clock forma…
Peaceful coexistence of thermal equilibrium and the emergence of time
Tommaso Favalli, Augusto Smerzi
We consider a quantum Universe composed by a small system S and a large environment. It has been demonstrated that, for the vast majority of randomly chosen wave-functions of the U…
Time Observables in a Timeless Universe
Tommaso Favalli, Augusto Smerzi
Time in quantum mechanics is peculiar: it is an observable that cannot be associated to an Hermitian operator. As a consequence it is impossible to explain dynamics in an isolated…
