  We study the spectral functions of fermionic operators in 1+1 dimensional
SU(N) Super Yang-Mills theory with 16 supercharges at finite density using the
holographically dual D1-brane geometry. This system exhibits quasi-particle
peaks indicating the existence of Fermi points about which excitations have a
finite relaxation time, in contrast with the Tomonaga-Luttinger model. The
finite width may be attributed to the non-trivial interactions of the probe
operators with the background density matrix, modeled holographically as a
charged black hole. We show that the fermionic correlators can in fact be
deduced from known results for fermion probes of the charged AdS4 black hole
background, owing to some remarkable coincidences in supergravity truncations.
