In this letter, we study the scattering of particles from a spin-independent parity time complex potential, and for the first time, theoretically demonstrate the coexistence of and -broken phases for broadband energy spectra in this system. We also show the existence of anisotropic transmission resonances, accessible through the tuning of energy. Our results are promising for applications in spintronics, semiconductor-based devices, and a better understanding of the topological surface states.
