‎Coherent Light Emission From GaAs Junctions. - [THE INVENTION OF THE LASER DIODE]‎

‎(New York), American physical Society, 1962. Lex8vo. Volume 9, No. 9, November 1, 1962 of ""Physical Review Letters"", In the original printed blue wrappers. A very nice and clean copy externally as well as internally, near mint. Pp. 366-368. [Entire issue: 361-414].‎

‎First edition of this groundbreaking paper in which the first demonstration of a coherent light emission from a semiconductor diode or laser diode is presented. The semiconductor laser is built upon Gallium arsenide (GaAs) which is a compound of the elements gallium and arsenic. It is a III/V semiconductor, and is used in a wide variety of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows.Later advances and improvements in materials has made the injection laser a fundamental and essential device in many important systems such as DVD- and CD-players.‎

[Entire issue: Pp. 687-720].‎

‎Rare first appearance of Hawking's first published paper, published a year before his Ph.D. was approved. It signposted the beginning of the area of research in black holes and singularities in general. Shortly after the present paper was published, Hawking followed up with three other seminal papers, in which he applied the Penrose-singularity (that a gravitationally collapsing star will inevitably end in a space-time singularity) to the whole universe. This resulted in his famous conclusion that: ""Yes, a universe governed by the classical (i.e., nonquantum) general theory of relativity must necessarily have started in a space-time singularity"" (Kragh, Cosmology and Controversy).When Hawking began his graduate studies, there was much debate in the physics community about the prevailing theories of the creation of the universe: the Big Bang and Steady State theories. Inspired by Roger Penrose's theorem of a spacetime singularity in the centre of black holes, Hawking applied the same thinking to the entire universe and during 1965, he wrote his thesis and the present paper on this topic. ""Hawking [in the present paper] realized that closed trapped surfaces, in its past version, will be present in any expanding Universe close to be spatially homogeneous and isotropic. This started a series of papers by him, Ellis, Geroch and others on the question of the inevitability of an initial singularity in our past if GR is assumed to hold and some reasonable conditions are met.""

‎First printing of Heiseberg's seminal and groundbreaking paper which laid the foundation for matrix mechanics and thereby giving birth to modern quantum mechanics"" a theory that states quantum mechanics should be based ""exclusively on relationship between quantities which in principle are observable"" (From the abstract). ""The alternative, which he [Heisenberg] chose in his historic paper [the present] and which led to the development of matrix machanics, the earliest formulation of modern quantum mechanics, abandoned Bohr's description of motion in terms of classical physics altogether and replaced it by a description in terms of what Heisenberg regarded as observable magnitudes"" (Jammer, The Conceptual Development of Quantum Mechanics, P. 197).""After nearly two weeks on Helgoland, Heisenberg returned to Göttingen, where he drafted his fundamental paper ""Über die quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen,"" which he completed in July. In this paper Heisenberg proclaimed that the quantum mechanics of atoms should contain only relations between experimentally observable quantities. Theresulting formalism served as the starting point for the new quantum mechanics, based, as Heisenberg's multiplication rule implied, on the manipulation of ordered sets of data forming a mathematical matrix."" (DSB)Before Heisenberg's discovery the Bohr-Sommerfeld quantum theory was the leading theory. By the early 1920's most physicists agreed that the Bohr-Sommerfeld theory had problems and that there was a need to replace it with a new quantum theory. Heisenberg's main achievement was to replace the idea of orbital path with what could be observed, namely the light emitted and absorbed by the atoms. Because of the unfamiliar mathematics which Heisenberg's new theory used, several physicists had doubts about its consistency. But Max Born soon realized that the laws, which the theory relied on, were the same as the laws, which apply to matrix algebra. In 1925 Born and his student Pascual Jordan published ""Zur Quantenmechanik"" which reformulated Heisenbergs theory in terms of matrices, in the special case of one degree of freedom. With ""Zur Quantenmechanik II"" (or the ""Three Man Paper"") published 1926, Heisenberg, Born and Jordan described the new theory in the general case of arbitrarely many freedom degrees.‎

‎First printings of these four absolutely fundamental papers, which together MARK THE TURNING POINT IN THE FABRICATION OF A NEW PHYSICS, Quantum Mechanics, also called ""Matrix Mechanics"".""In May 1925, Heisenberg took on a new and difficult problem, the calculation of the line intensities of the hydrogen spectrum. Just as he had done with Kramers and Bohr, Heisenberg began with a Fourier analysis of the electron orbits. When the hydrogen orbit proved too difficult, he turned to the anharmonic oscillator. With a new multiplication rule relating the amplitudes and frequencies of the Fourier components to observed quantities, Heisenberg succeeded in quantizing the equations of motion for this system in close analogy with the classical equations of motion.....in June Heisenberg returned to Göttingen, where he drafted his fundamental paper [the first paper offered], which he completed in July. In this paper Heisenberg proclaimed that the quantum mechanics of atoms should contain only relations between experimentally observable quantities. The resulting formalism served as the starting point for the new quantum mechanics, based, as Heisenberg's multiplication rule implied, on the manipulation of ordered sets of data forming a mathematical matrix....Born and his assistant, Pascual Jordan, quickly developed the mathematical content of Heisenberg's work into a consistent theory with the help of abstract matrix algebra [the second paper offered].Their work, in collaboration with Heisenberg, culminated in their ""three-man paper"" [""Dreimännerarbeit"" - the third paper offered] that served as the foundation of matrix mechanics. Confident of the correctness of the new theory, Heisenberg, Pauli, Born, Dirac, and others began applying the difficult mathematical formalism to the solution of lingering problems."" (DSB).In the last paper offered, the Pauli-paper, he shows that the hydrogen spectrum can be derived from the new theory. His starting-point constitutes, due to Lez, a method for integrating the classical equations of motion of a particle in a Coulomb field. Pauli's paper was received on January 17, 1926, but the main result must have been obtained before November 3, 1925, for on that date, Heisenberg writes Pauli: ""..Ich brauche Ihnen wohl nicht zu schreiben, wie sehr ich mich über die neue Theorie des Wasserstoffs freue..."" Pauli's paper convinced most physicists that Quantum Mechanics is correct. (Van der Waerden).‎
