Konfigurationsraum und Zweite Quantelung. - [FOCK SPACE]
Berlin, Springer, 1932. 8vo. Bound in contemporary half cloth with gilt lettering, In ""Zeitschrift für Physik"", Band 75, 1932. Entire issue offered. Two stamps to title page, otherwise fine. Pp. 622-647. [Entire volume: VIII, 850 pp + frontiespiece].
First appearance of Fock's seminal paper in which he introduced his algebraic construction used in quantum mechanics to construct the quantum states space of a variable or unknown number of identical particles from a single particle Hilbert space, often referred to as Fock space. Technically, the Fock space is (the Hilbert space completion of) the direct sum of the symmetric or antisymmetric tensors in the tensor powers of a single-particle Hilbert space H.""Between 1928 and 1934, Fok obtained important results in the quantum field theory. He completed the mathematical method of secondary quantization proposed by Paul A.M. Dirac and developed by Pascual Jordan and Eugene Wigner. It has been shown that this method does not go beyond the traditional framework of quantum mechanics (as Jordan argued) and that the two ways of description are completely equivalent. As early as 1934 Fok suggested describing a system with a variable number of particles (bosons) in the representations of the secondary quantization with the aid of a generating functional (""Fok’s functional"").In his papers Fok introduced a number of new notions. such as ""the Fok space"" (a Hilbert space in the representation of secondary quantization). In papers written with Dirac and Boris Podolsky (1932), Dirac’s results on interaction of charged particles by the exchange of virtual photons were extended. The one-dimensional problem solved by Dirac was generalized to the realistic three-dimensional case: the multitime formalism of Dirac, Podolsky, and Fok was introduced"" and quantum electrodynamics was formulated in its modern form."" (DSB).

Beweis des Adiabatensatzes. - [ADIABATIC THEOREM]
Berlin, Springer, 1928. 8vo. Bound in contemporary half cloth with gilt lettering, In ""Zeitschrift für Physik"", Band 51, 1928. Entire issue offered. Two stamps to title page, otherwise fine. Pp. 165-80. [Entire volume: VII, (1) 903 pp].
First appearance of Born and Fock's important paper in which they introduced their adiabatic theorem, a concept in quantum mechanics which they stated as follows: "" A physical system remains in its instantaneous eigenstate if a given perturbation is acting on it slowly enough and if there is a gap between the eigenvalue and the rest of the Hamiltonian's spectrum."" (From the present paper). The concept of this theorem deals with the time-dependent Hamiltonian - a subject of Quantum dynamics - where the Hamiltonian changes with time.The present issue also contain Gamow's ""Zur Quantentheorie des Atomkernes"" containing the first direct calculation of the Geiger-Nuttall law.
Neue Unbestimmtheitseigenschften des elektromagnetischen Feldes.
Berlin, Springer, 1930. 8vo. In contemporary halv cloth with gilt lettering to spine. In ""Zeitschrift für Physik"", Bd. 66, 1930. Entire issue offered. Stamp to front free end-paper and titlepage, otherwise fine and clean. Pp. 178-81. [Entire volume: IV, 401 pp.].
First printing of Jordan and Fock's paper on what they called: ""new uncertainty characteristics and electromagnetic fields"". Here they examined how the quantized field strengths in Dirac's theory were to be measured and the status of the uncertainty relations with respect to these quantities. These examinations caused that for a while it seemed that particle theory and field theory might be in conflict.
