Sichuan University scholar publishes PRL, proposes new channel for probing quantum gravity
Recently, Dr. Andrea Addazi and co-workers from the School of Physics, Sichuan University published a high-level paper in the top international physics journal Physical Review Letters, proposing a new channel to explore quantum gravity, with Sichuan University as the first and corresponding author. Andrea Addazi joined Sichuan University as an introduced talent in November 2019.
The bubble incompatibility principle refers to the fact that only one fermion is allowed to exist on the same quantum state, which is derived from the spin-statistics theorem and is closely related to causal determinism, Lorentz symmetry and spacetime microstructure, and plays an important role in modern physics. It has been shown that quantum gravitational effects can induce the failure of the bubble incompatibility principle, so the experimental detection of this principle will provide new clues for the discovery of new physics at the Planck scale. One representative experiment among many is the VIP experiment (VIolation of the Pauli exclusion principle) conducted at the Gran Sasso National Laboratory (Italy). The main goal of this experiment is to measure the probability of certain rare atomic orbital jumps. These orbital jumps are forbidden in the traditional Pauli incompatibility principle, but would be allowed in a quantum gravity model with non-parity spacetime coordinates, and the corresponding jumps can be calculated.
