15-1-21 Hamiltonian (quantum mechanics) - Wikipedia, the free encyclopedia Hamiltonian (quantum mechanics) From Wikipedia, the free encyclopedia In quantum mechanics, the Hamiltonian is the operator corresponding to the total energy of the system. It is usually denoted by H, also ? or ?. Its ...
Historically this fact became obvious as soon as modern quantum mechanics was constituted by Heisenberg, Schrdinger, Dirac and others. Schrdinger himself used a term for this mathematical object that translates to " the wave operator analogous to the Hamiltonian function " [5] in comparing his ...
in the Supplementary Materials].We can now explicitly write the Hamiltonian-density operator taking into account all the constraints of the Poincaré. With the help of the set of equations [eqs (4), (5) and (7)] and the constraints [...
The relationship between the continuity equation and the Hamiltonian H of a quantum system is investigated from a nonstandard point of view. In contrast to the usual approaches, the expression of the current density J ψ is given ab initio by means of a transport-velocity operator V T , whos...

In order to take advantage of the nearsightedness of electronic matter29, the Hamiltonian operator is expressed in the picture of localized pseudo-atomic orbital (PAO) basis. The basis is separated into radial and angular parts, having the form\({\phi }_{i\alpha }({{{\bf{r}}})={R}...
In the early years of quantum mechanics, energy and time were believed to be related similarly, by a so-called time-energy uncertainty relation (TEUR), though a similar proof does not apply since time is not an operator. Several alternative formulations of the TEUR were studied2,3,4,5. ...
