En la misma época en la que Heisenberg encontraba su modelo de la mecánica cuántica, Erwin Schrödinger encontraba otra solución, que luego se vió que era equivalente. En el capítulo 6 de su biografía científica, leo el recuerdo de Heisenberg de esos tiempos:

During the first few months of 1926, at about the same time that I delivered my lecture in Berlin, G6ttingen first became familiar with the work of the Viennese physicist, Erwin Schrodinger, who was approaching atomic theory from an entirely fresh side. The year before, Louis de Broglie in France had drawn attention to the fact that the strange wave-particle dualism which, at the time, seemed to prevent a rational explanation of light phenomena might be equally involved in the behavior of matter, for instance of electrons. Schrodinger developed this idea further and, by means of a new wave equation, formulated the law governing the propagation of material waves under the influence of an electromagnetic field. In Schrodinger's model, the stationary states of an atomic shell are compared with the stationary vibrations of a system, for instance of a vibrating string, except that all the magnitudes normally considered as energies of the stationary states are treated as frequencies of the stationary vibrations. The results Schrodinger obtained in this way fitted in very well with the new quantum mechanics, and Schrodinger quickly succeeded in proving that his own wave mechanics was mathematically equivalent to quantum mechanics; in other words, that the two were but different mathematical formulations of the same structures. Needless to say, we were delighted by this new development, for it greatly strengthened our confidence in the correctness of the new mathematical formulation. Moreover, Schrodinger's procedure lent itself readily to the simplification of calculations that had severely strained the powers of quantum mechanics.

Todo se dispara con la propuesta de de Broglie, que estaba madura para caer en esos tiempos. Ver

La Ecuación de Schrödinger (1) Introducción

El camino de Schrödinger era más potable para muchos físicos, porque acudía a funciones, derivadas, ondas, todos elementos más familiares que las matrices de Heisenberg. Si bien a Heisenberg le interesó el trabajo de Schrödinger, también pensaba que estaba en alguna parte errado, porque era una especie de vuelta a "lo clásico", cuando él quería destacar que había una nueva mecánica. Veremos esto en el próximo post.

Nos leemos!
