Spectral statistics for ensembles of various real random matrices

Sachin Kumar, Zafar Ahmed

We investigate spacing statistics $p (s)$ and distribution of eigenvalues $D (ε)$ for ensembles of various real random matrices (of order $n \times n, n = 2$ and $n >> 2$ ) where the matr…

Zero width resonance (spectral singularity) in a complex PT-symmetric potential

Zafar Ahmed

We show that the complex PT-Symmetric potential, $V (x) = - V_{1} sec h^{2} x + i V_{2} sec h x tanh x,$ , entails a single zero-width resonance (spectral singularity) when $V_1+|V_2|=4n^2+…
