Origin of maximal symmetry breaking in even<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi mathvariant="script">PT</mml:mi></mml:math>-symmetric lattices
By investigating a parity- and time-reversal- ($\mathcal{P}\mathcal{T}$-) symmetric, $N$-site lattice with impurities $\ifmmode\pm\else\textpm\fi{}i\ensuremath{\gamma}$ and hopping amplitudes ${t}_{0}\phantom{\rule{0.28em}{0ex}}({t}_{b})$ for regions outside (between) the impurity locations, we probe the interimpurity-distance dependence of the critical impurity strength and the origin of maximal $\mathcal{P}\mathcal{T}$-symmetry breaking that occurs when the impurities are nearest neighbors.
