A general approach to quantum Hall hierarchies
quantum Hall hierarchies
font style='font-size:12px;'>
2010/11/25
The abelian hierarchy of quantum Hall states accounts for most of the states in the
lowest Landau level, and there is evidence of a similar hierarchy of non-abelian states
emanating from the ν = 5/2...
