Reflection positivity and a refined index for 2d invertible phases

Nikita Sopenko

We analyze the validity of reflection positivity in the classification of invertible phases of quantum spin systems. We provide a mathematical model in which every 2d invertible st…

Optimal bound on long-range distillable entanglement

Jonah Kudler-Flam, Vladimir Narovlansky, Nikita Sopenko

We prove an upper bound on long-range distillable entanglement in spatial dimensions. Namely, it must decay faster than , where is the distance between entangled regio…
