Hiroshi Enatsu

Hiroshi Enatsu (12 September 1922 - 4 August 2019) was a Japanese theoretical physics who contributed to a special relativity Hamiltonian mechanics formalism in quantum field theory. 
Enatsu has found Matej Pavšič, "The Landscape of Theoretical Physics: A Global View, From Point Particles to the Brane World and Beyond, in Search of a Unifying Principle", Kluwer Academic, 2001that the Canonical commutation relation Relativistic Hamiltonian Formalism in Quantum Field Theory and Micro-Noncausality, August 1963
[\psi (x, \tau), \psi ^*(x', \tau)] = \delta ( x - x' ) in a relativistic Hamiltonian formalism 
is equivalent to that in the conventional non-relativistic Hamiltonian formalism of quantum field theory, 
where [\psi, \phi] = \psi \phi - \phi \psi is the commutator, 
 x is spacetime coordinates, 
\tau is proper time, 
\psi ^* is Hermitian adjoint of \psi, 
and \delta (x) is the Dirac delta function, 
with the aid of the relation
\epsilon ( x - x' ) \epsilon ( \tau - \tau' )=1.
