Query: Emergence of Neutral Modes in Laughlin-like Fractional Quantum Hall
  Phases   Chiral gapless boundary modes are characteristic of quantum Hall (QH) states.
For hole-conjugate fractional QH phases counter-propagating edge modes
(upstream and downstream) are expected. In the presence of electrostatic
interactions and disorder these modes may renormalize into charge and upstream
neutral modes. Orthodox models of Laughlin phases anticipate only a downstream
charge mode. Here we show that in the latter case, in the presence of a smooth
confining potential, edge reconstruction leads to the emergence of pairs of
counter-propagating modes, which, by way of mode renormalization, may give rise
to non-topological upstream neutral modes, possessing non-trivial statistics.
This may explain the experimental observation of ubiquitous neutral modes, and
the overwhelming suppression of anyonic interference in Mach-Zehnder
interferometry platforms. We also point out other signatures of such edge
reconstruction.
