Quantum information of a free fermion in 1+1 dimensions — •Christian Simon — Institut für Theoretische Physik und Astrophysik, Universität Würzburg, 97074 Würzburg, Germany

The free fermion in 1+1 dimensions provides a solvable yet non-trivial model for studying quantum information aspects in QFT. A key concept is the entanglement (or modular) Hamiltonian which gives the entanglement spectrum. We study the associated modular flow induced by it, focusing on the non-local part in different spin sectors. Non-locality in quantum physics has recently appeared to play an important role in the emergence of spacetime in the AdS/CFT correspondence which we seek to understand better.
