Longitudinal-field fidelity susceptibility analysis of the $J_{1}$ - $J_{2}$ transverse-field Ising model around $J_{2} / J_{1} \approx 0.5$

Yoshihiro Nishiyama

The square-lattice $J_{1}$ - $J_{2}$ transverse-field (TF) Ising model was investigated with the exact diagonalization (ED) method. In order to analyze the TF-driven phase transition, we…
