Query: Russian doll spectrum in a non-Abelian string-net ladder   We study a string-net ladder in the presence of a string tension. Focusing on
the simplest non-Abelian anyon theory with a quantum dimension larger than two,
we determine the phase diagram and find a Russian doll spectrum featuring
size-independent energy levels as well as highly degenerate zero-energy
eigenstates. At the self-dual points, we compute the gap exactly by using a
mapping onto the Temperley-Lieb chain. These results are in stark constrast
with the ones obtained for Fibonacci or Ising theories.
