Query: Non-abelian Thouless pumping in a photonic lattice   Non-abelian gauge fields emerge naturally in the description of adiabatically
evolving quantum systems having degenerate levels. Here we show that they also
play a role in Thouless pumping in the presence of degenerate bands. To this
end we consider a photonic Lieb lattice having two degenerate non-dispersive
modes and we show that, when the lattice parameters are slowly modulated, the
propagation of the photons bear the fingerprints of the underlying non-abelian
gauge structure. The non-dispersive character of the bands enables a high
degree of control on photon propagation. Our work paves the way to the
generation and detection of non-abelian gauge fields in photonic and optical
lattices.
