August Krönig
August Karl Krönig (; 20 September 1822 – 5 June 1879) was a German chemist and physicist who published an account of the kinetic theory of gases in 1856, probably after reading a paper by John James Waterston. Biography Krönig was born in Schildesche, now part of Bielefeld. After completing his Abitur he attended the University of Bonn for three semesters beginning in 1839 studying primarily Oriental languages. In 1840 he changed focus to physics, chemistry and mathematics and transferred to the University of Berlin, where he completed his doctorate in 1845 with a thesis on chromate salts. He then taught at two schools in Berlin, the ''Realgymnasium'' in Cölln and the ''Königliche Realschule'' attached to the Friedrich-Wilhelms-Gymnasium in Berlin. In 1864 he was given a professorship, but he was forced to retire the same year for reasons of ill health. In 1851 Krönig self-published the ''Journal für Physik und physikalische Chemie des Auslandes in vollständigen Üb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralph Kronig
Ralph Kronig (10 March 1904 – 16 November 1995) was a German physicist. He is noted for the discovery of particle spin and for his theory of X-ray absorption spectroscopy. His theories include the Kronig–Penney model, the Coster–Kronig transition and the Kramers–Kronig relations. Background Ralph Kronig (later Ralph de Laer Kronig) was born on 10 March 1904 to German parents (Harold Theodor Kronig, Augusta de Laer) in Dresden, Germany. He died in Zeist on 16 November 1995 at the age of 91. Kronig received his primary and high-school education in Dresden and went to New York City to study at Columbia University where he received his PhD in 1925 and subsequently became instructor (1925) and assistant professor (1927). Early in Kronig's career he had encountered Paul Ehrenfest who, while visiting America in 1924, had advised the young physicist Ralph Kronig to revisit Europe. Kronig left for that continent later in 1924 and paid visits to the important centers for theoreti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kramers–Kronig Relations
The Kramers–Kronig relations are bidirectional mathematical relations, connecting the real and imaginary parts of any complex function that is analytic in the upper half-plane. The relations are often used to compute the real part from the imaginary part (or vice versa) of response functions in physical systems, because for stable systems, causality implies the condition of analyticity, and conversely, analyticity implies causality of the corresponding stable physical system. The relation is named in honor of Ralph Kronig and Hans Kramers. In mathematics, these relations are known by the names Sokhotski–Plemelj theorem and Hilbert transform. Formulation Let \chi(\omega) = \chi_1(\omega) + i \chi_2(\omega) be a complex function of the complex variable \omega , where \chi_1(\omega) and \chi_2(\omega) are real. Suppose this function is analytic in the closed upper half-plane of \omega and vanishes faster than 1/, \omega, as , \omega, \to \infty. Slightly weaker conditi ...
