"Zur Theorie der Metalle" in Zeitschrift für Physik, Volume 71, 1931, pp. 205-226

Berlin: Julius Springer, 1931. 1st Edition. FIRST EDITION OF HANS BETHE’S NOW FAMOUS ANSATZ, "the first time a strongly interacting many-body system has been 'solved exactly'" (Weiss, Reflected Brownian Motion, 1). Bethe's ansatz, or approach, provides exact solutions of certain one-dimensional quantum many-body models. It has been used to solve "genuine interacting quantum man-body systems for which perturbative approaches and mean-field theories often fail. In the case of interacting bosons and fermions, the spatial confinement to one dimension leads to enhanced dynamics and correlations, and ultimately to new quantum phases” (Batchelor, "The Bethe Ansatz after 75 Years" in Physics Today, 2007).

The 75th anniversary of Bethe's Ansatz was celebrated for its "profound influence on the field of exactly solved models in statistical mechanics to insights into the subtle nature of quantum many-body effects observed in cold quantum gases" (ibid). Today, Bethe’s approach and solution to a quantum mechanical model has found its way to everything from superconductors to string theory. Despite its widely praised rigorous mathematical structure and the richness of the results it yielded, Bethe's paper lay in obscurity for decades.
