Abstract:
We consider fermionic and bosonic quantum chains where a defect separates two
subsystems and compare the corresponding entanglement spectra. With these, we
calculate their Rényi entanglement entropies and obtain analytical formulae
for the continuously varying coefficient of the leading logarithmic term. For
the bosonic case we also present numerical results.
