Query: Spin-Selective Equilibration among Integer Quantum Hall Edge Channels   The equilibration between quantum Hall edge modes is known to depend on the
disorder potential and the steepness of the edge. Modern samples with higher
mobilities and setups with lower electron temperatures call for a further
exploration of the topic. We develop a framework to systematically measure and
analyze the equilibration of many (up to 8) integer edge modes. Our results
show that spin-selective coupling dominates even for non-neighboring channels
with parallel spin. Changes in magnetic field and bulk density let us control
the equilibration until it is almost completely suppressed and dominated only
by individual microscopic scatterers. This method could serve as a guideline to
investigate and design improved devices, and to study fractional and other
exotic states.
