Entanglement Gap and a New Principle of Adiabatic Continuity
Entanglement Gap and a New Principle of Adiabatic Continuity
We give a complete definition of the entanglement gap separating low-energy, topological levels, from high-energy, generic ones, in the "entanglement spectrum" of Fractional Quantum Hall (FQH) states. By removing the magnetic length inherent in the FQH problem - a procedure which we call taking the "conformal limit", we find that …
