Average eigenstate entanglement entropy of the XY chain in a transverse field and its universality for translationally invariant quadratic fermionic models
Lucas Hackl, Lev Vidmar, Marcos Rigol +1
We recently showed [Phys. Rev. Lett. 121, 220602 (2018)] that the average bipartite entanglement entropy of all energy eigenstates of the quantum Ising chain exhibits a universal (…
Volume Law and Quantum Criticality in the Entanglement Entropy of Excited Eigenstates of the Quantum Ising Model
Lev Vidmar, Lucas Hackl, Eugenio Bianchi +1
Much has been learned about universal properties of entanglement entropies in ground states of quantum many-body lattice systems. Here we unveil universal properties of the average…
Entanglement Entropy of Eigenstates of Quadratic Fermionic Hamiltonians
Lev Vidmar, Lucas Hackl, Eugenio Bianchi +1
In a seminal paper [D. N. Page, Phys. Rev. Lett. 71, 1291 (1993)], Page proved that the average entanglement entropy of subsystems of random pure states is $S_{\rm ave}\simeq\ln{\c…
