PT-Symmetric $S U (2)$ -like Random Matrix Ensembles: Invariant Distributions and Spectral Fluctuations

Stalin Abraham, A. Bhagwat, Sudhir Ranjan Jain

We consider an ensemble of $2 \times 2$ normal matrices with complex entries representing operators in the quantum mechanics of 2 - level parity-time reversal (PT) symmetric systems…

On Classification and Geometric Characterizations of Ensembled $2 \times 2$ Pseudo Hermitian and PT-Symmetric Matrices

Stalin Abraham, Ameeya A. Bhagwat

Non-Hermitian matrices $H \in M_{2} (C)$ satisfying the relation $H^{a^} G = G H$ , for invertible and singular Hermitian matrices $G$ have been studied. The matrices $H$ corres…
