Gauging anomalous unitary operators
Yuhan Liu, Hassan Shapourian, Paolo Glorioso +1
Boundary theories of static bulk topological phases of matter are obstructed in the sense that they cannot be realized on their own as isolated systems. The obstruction can be quan…
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 spectrum of random mixed states: A diagrammatic approach
Hassan Shapourian, Shang Liu, Jonah Kudler-Flam +1
The entanglement properties of random pure states are relevant to a variety of problems ranging from chaotic quantum dynamics to black hole physics. The averaged bipartite entangle…
Andreev reflection in the fractional quantum Hall state
Önder Gül, Yuval Ronen, Si Young Lee +8
We construct high-quality graphene-based van der Waals devices with narrow superconducting niobium nitride (NbN) electrodes, in which superconductivity and robust fqH coexist. We f…
