We investigate the superfluidity of indirect momentum space dark dipolar excitons in a double layer of tilted 1T′-MoS₂ with Dirac bands. By considering the effects of an external vertical electric field and circularly polarized light, we analyze the exciton binding energies, wave functions, and critical temperature for superfluidity. Our calculations reveal that the anisotropic Bose gas of two-component excitons exhibits anisotropic critical velocity, collective excitations, and concentrations of the superfluid and normal component. We propose an experimental approach using phonon-assisted photoluminescence to observe the directional superfluidity of the indirect momentum space dark excitons in the double layer of 1T′-MoS₂.
