Heisenberg equation of motion -- Partial derivative question
2021年4月23日 · The Heisenberg equation of motion is a fundamental equation in quantum mechanics that describes how a quantum system evolves over time. It is based on the principle of Heisenberg's uncertainty principle, which states that the more precisely we know the position of a particle, the less precisely we can know its momentum, and vice versa.

2020年12月20日 · In this paper, in Appendix A, it is said the Liouville representation of the Heisenberg equation is given by \begin{equation} \frac{\mathrm{d}}{\mathrm{d}t}\vec{v}(t)=\left(\frac{\mathrm{i}}{\hbar}\left[H(t),\cdot\right]+\frac{\partial}{\partial t}\right)\vec{v}(t). \end{equation} I cannot really make any sense of this equation and I am not ...
Heisenberg equation with time-dependent Hamiltonian
It is the root of quantum mechanics that Heisenberg picture and Schrödinger picture are equivalent? In most textbooks and wikipedia, the equivalence is proved with a time-independent Hamiltonian.
Schrodinger equation and Heisenberg equation of motion
2017年8月13日 · The Heisenberg equation of motion is another fundamental equation in quantum mechanics that describes the time evolution of a quantum system. Unlike the Schrodinger equation, it describes the time evolution of the operators that represent physical observables, such as position and momentum.
