Locality and Exceptional Points in Pseudo-Hermitian Physics
Jacob L. Barnett
Pseudo-Hermitian operators generalize the concept of Hermiticity. This class of operators includes the quasi-Hermitian operators, which reformulate quantum theory while retaining r…

Effects of detuning on -symmetric, tridiagonal, tight-binding models
Jacob L. Barnett, Yogesh N. Joglekar
Non-Hermitian, tight-binding -symmetric models are extensively studied in the literature. Here, we investigate two forms of non-Hermitian Hamiltonians to study the $\…
