# Entanglement negativity of fermions: Monotonicity, separability criterion, and classification of few-mode states

Author(s): Hassan Shapourian and Shinsei Ryu
We study quantum information aspects of the fermionic entanglement negativity recently introduced [H. Shapourian et al., Phys. Rev. B 95, 165101 (2017)] based on the fermionic partial transpose. In particular, we show that it is an entanglement monotone under the action of local quantum operations ...
