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.
Academic works
Enatsu has found [1]that the Canonical commutation relation [2] <math>[\psi (x, \tau), \psi ^*(x', \tau)] = \delta ( x - x' )</math> in a relativistic Hamiltonian formalism is equivalent to that in the conventional non-relativistic Hamiltonian formalism of quantum field theory, where <math>[\psi, \phi] = \psi \phi - \phi \psi</math> is the commutator, <math> x </math> is spacetime coordinates, <math>\tau</math> is proper time, <math>\psi ^*</math> is Hermitian adjoint of <math>\psi</math>, and <math>\delta (x)</math> is the Dirac delta function, with the aid of the relation <math>\epsilon ( x - x' ) \epsilon ( \tau - \tau' )=1</math>.
