I Is there any operator for momentum in terms of t?

[Aswin Sasikumar 1729]

Since there is an energy operator interms of t and a momentum operator interms of x as expected.For energy there is a hamiltanion operator interms of t which is unexpected for me.Similarly whether there is any operator interms of t for momentum also?

 

[Simon Bridge]

Off the kinetic energy operator: $2m\hat T=\hat p^2$ ...
Note: the Hamiltonian operator is the energy operator.

Please provide example of "energy operator in terms of t".

ih/2π *∂/∂t is an operator of energy

This is misleading since time is a parameter in quantum theory not an observable, represented by an operator. The Hamiltonian represents the total energy of the system and is a function (or functional) of the fundamental operators of the theory's observable algebra like $\hat{\vec{x}}$ and $\hat{\vec{p}}$ for one particle in non-relativistic quantum theory ("first quantization") or the field operators in quantum field theories ("second quantization").
