Topological Modes in Monitored Quantum Dynamics
Haining Pan, Hassan Shapourian, Chao-Ming Jian
Dynamical quantum systems both driven by unitary evolutions and monitored through measurements have proved to be fertile ground for exploring new dynamical quantum matters. While t…

Anyonic Partial Transpose I: Quantum Information Aspects
Hassan Shapourian, Roger S. K. Mong, Shinsei Ryu
A basic diagnostic of entanglement in mixed quantum states is known as the partial transpose and the corresponding entanglement measure is called the logarithmic negativity. Despit…

Entanglement negativity of fermions: monotonicity, separability criterion, and classification of few-mode states
Hassan Shapourian, Shinsei Ryu
We study quantum information aspects of the fermionic entanglement negativity recently introduced in [Phys. Rev. B 95, 165101 (2017)] based on the fermionic partial transpose. In p…
