Rényi-like entanglement probe of the chiral central charge
Julian Gass, Michael Levin
We propose a ground state entanglement probe for gapped, two-dimensional quantum many-body systems that involves taking powers of reduced density matrices in a particular geometric…

Physical proof of the topological entanglement entropy inequality
Michael Levin
Recently it was shown that the topological entanglement entropy (TEE) of a two-dimensional gapped ground state obeys the universal inequality , where is…

Many-body systems with spurious modular commutators
Julian Gass, Michael Levin
Recently, it was proposed that the chiral central charge of a gapped, two-dimensional quantum many-body system is proportional to a bulk ground state entanglement measure known as…
