The localization length of the non-Hermitian skin effect is encoded in the quantum metric of right eigenstates, exhibiting power-law divergences at gapless points and discontinuities at cusps of the generalized Brillouin zone.
Non-Hermitian Gamma interaction in the transverse-field Ising chain creates a gapless phase with long-range spin-nematic order from PT symmetry breaking and produces dynamical spin-nematic signatures for phase characterization.
