dc.description.abstract | We study the spectral function of holographic fermions with Pauli term. We find the k-dependent instability signaled by the tachyonic spectrum (k-gap) from the m ˃ 1/2 regime where unitarity is violated. We suggest that this is the instability toward the charge density wave (CDW) based on the similarity of the unitarity violation in conformal field theory (CFT) and the nesting Fermi surface phenomena in weakly interaction system: both of them give divergent enhancement of degree of freedom. | en_US |
