If $(E,g,w)$ is a vector space $E$ with a metric $g$ and a symplectic form $w$; then we can define the complex parts $(1,0)$ and $(0,1)$, so that the complex Clifford algebra is: $$e_1 . f_1 + f_1 . e_1= -2 g(e,f)$$ $$e_0 . f_0 + f_0 . e_0=-2 g(e,f)$$ $$e_1 .f_0 - f_0 . e_1= w(e,f)$$ with $e_1$ in the $(1,0)$ part and $e_0$ in the $(0,1)$ part. Could we define from this algebra (mixed between the Clifford algebra and the Heisenberg algebra) the Dirac operator?
