Classical and Quantum Fermions Linked by an Algebraic Deformation

Ali Mostafazadeh

We study the regular representation $ρ_{ζ}$ of the single-fermion algebra $A_{ζ}$ , i.e., $c^{2} = c^{+ 2} = 0$ , $c c^{+} + c^{+} c = ζ 1$ , for $ζ \in [0, 1]$ . We show that $ρ_{0}$ is a four-dimensio…

Pseudo-Unitary Operators and Pseudo-Unitary Quantum Dynamics

Ali Mostafazadeh

We consider pseudo-unitary quantum systems and discuss various properties of pseudo-unitary operators. In particular we prove a characterization theorem for block-diagonalizable ps…
