Gravitational back-reaction is magical
ChunJun Cao, Gong Cheng, Alioscia Hamma +3
We study the interplay between magic and entanglement in quantum many-body systems. We show that non-local magic, which is supported by the quantum correlations is lower bounded by…
Stabilizer entropy of quantum tetrahedra
Simone Cepollaro, Goffredo Chirco, Gianluca Cuffaro +2
How complex is the structure of quantum geometry? In several approaches, the spacetime atoms are obtained by the SU(2) intertwiner called quantum tetrahedron. The complexity of thi…
Scrambling Power of Soft Photons
Xuan-Lin Su, Alioscia Hamma, Antonino Marciano
Observable scattering processes entail emission-absorption of soft photons. As these degrees of freedom go undetected, some information is lost. Whether some of this information ca…
Trapped surfaces and emergent curved space in the Bose-Hubbard model
Francesco Caravelli, Alioscia Hamma, Fotini Markopoulou +1
A Bose-Hubbard model on a dynamical lattice was introduced in previous work as a spin system analogue of emergent geometry and gravity. Graphs with regions of high connectivity in…
Hidden entanglement at the Planck scale: loss of unitarity and the information paradox
Michele Arzano, Alioscia Hamma, Simone Severini
We discuss how relaxing the requirement of locality for quantum fields can equip the Hilbert space of the theory with a richer structure in its multi-particle sector. A physical co…
