Daughter states and their non-Abelian parent quantum Hall phases
Non-Abelian phases remain among the most elusive and intriguing states of matter. The fractional quantum Hall effect, especially at even-denominator fillings, provides a promising platform where non-Abelian anyons may emerge. Yet, identifying the precise topological order remains a formidable challenge.
In this talk, I will introduce daughter states observed near even-denominator states in various materials, including bilayer graphene and wide quantum wells. I will explain their origin and show how their presence serves as a diagnostic tool of the non-Abelian order of their parent states. I will present numerical evidence confirming the relations between the non-Abelian parents and their corresponding daughters. I will discuss recent experiments that observed the daughter states and show how they offer a new, accessible route to identifying non-Abelian phases in quantum Hall systems.
