Abstract:
We consider fermionic chains where the two halves are either metals with
different bandwidths or a metal and an insulator. Both are coupled together by
a special bond. We study the ground-state entanglement entropy between the two
pieces, its dependence on the parameters and its asymptotic form. We also
discuss the features of the entanglement Hamiltonians in both subsystems and
the evolution of the entanglement entropy after joining the two parts of the
system.
