Spectral Weight Suppression and Fermi Arc-like Features with Strong Holographic Lattices

Understand

We investigate holographic fermions in uni-directional striped phases, where the breaking of translational invariance can be generated either spontaneously or explicitly.

• We solve the Dirac equation for a probe fermion in the associated background geometry.
• When the spatial modulation effect becomes sufficiently strong, we see a spectral weight suppression whenever the Fermi surface is larger than the first Brillouin zone.
• This leads to the gradual disappearance of the Fermi surface along the symmetry breaking direction, in all of the cases we have examined.
