  Motivated by multiple possible physical realizations, we study the SU(4)
quantum antiferromagnet with a fundamental representation on each site of the
triangular lattice. We provide evidence for a gapless liquid ground state of
this system with an emergent Fermi surface of fractionalized fermionic partons
coupled with a U(1) gauge field. Our conclusions are based on numerical
simulations using the density matrix renormalization group (DMRG) method, which
we support with a field theory analysis.
