Dynamical spin-nematic correlation in a transverse field Ising chain with non-Hermitian Gamma interaction
This study investigates how non-Hermiticity ($\Gamma$) and an off-diagonal interaction modify quantum phase transitions in a transverse field Ising chain. The research found a gapless phase induced by parity-time symmetry breaking, which exhibits long-range spin correlations. It also establishes that dynamical spin-nematic correlation can be used to map out the static phase diagram.
