Roger James Elliott
Sir Roger James Elliott (8 December 1928 – 16 April 2018) was a British theoretical physicist specialising in the magnetic, semiconductor, and optical properties of condensed matter. Born in Chesterfield, Elliott obtained a DPhil in mathematics and theoretical physics from the University of Oxford in 1952. He was a research fellow at the University of California, Berkeley, in 1952–3, then at the Atomic Energy Research Establishment until 1955, when he was appointed to a lecturership at the University of Reading. He returned to the University of Oxford in 1957, where he was the Wykeham Professor of Physics from 1974 until 1988. He served as chief executive of Oxford University Press from 1988 until 1993. The Institute of Physics awarded the Maxwell Medal and Prize jointly to Elliott and Kenneth William Harry Stevens in 1968, and the Guthrie Medal and Prize to Elliott in 1990. Elliott was elected a fellow of the Royal Society in 1976 and knighted in 1987. He has been award ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert Einstein was concerned with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elliott Formula
The Elliott formula describes analytically, or with few adjustable parameters such as the dephasing constant, the light absorption or emission spectra of solids. It was originally derived by Roger James Elliott to describe linear absorption based on properties of a single electron–hole pair. Kuper, C. G.; Whitfield, G. D. (1963). ''Polarons and Excitons''. Plenum Press. LCC63021217 The analysis can be extended to a many-body investigation with full predictive powers when all parameters are computed microscopically using, e.g., the semiconductor Bloch equations (abbreviated as SBEs) or the semiconductor luminescence equations (abbreviated as SLEs). Background One of the most accurate theories of semiconductor absorption and photoluminescence is provided by the SBEs and SLEs, respectively. Both of them are systematically derived starting from the many-body/quantum-optical system Hamiltonian and fully describe the resulting quantum dynamics of optical and quantum-optical obs ...

Robert J
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and '' berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It c ...

Department Of Physics, University Of Oxford
The Department of Physics at the University of Oxford is located on Parks Road in Oxford, England. The department consists of multiple buildings and sub-departments including the Clarendon Laboratory, Denys Wilkinson's building, Dobson Square and the Beecroft building. Each of these facilities contribute in studying different sub-types of physics such as Atomic and Laser Physics, Astrophysics, Theoretical Physics, etc. The physics division have made scientific contributions towards this branch of science since the establishment of the department. Facilities Clarendon Laboratory The Clarendon Laboratory was constructed at the University of Oxford in 1872. The building was named after Edward Hyde, who was the 1st Earl of Clarendon, making it the oldest physics laboratory built in England. The Clarendon building was designed by a British scientist named Robert Bellamy Clifton, who made the laboratory a space for undergraduates to prepare for their examinations rather than for ...

Doctor Of Science
Doctor of Science ( la, links=no, Scientiae Doctor), usually abbreviated Sc.D., D.Sc., S.D., or D.S., is an academic research degree awarded in a number of countries throughout the world. In some countries, "Doctor of Science" is the degree used for the standard doctorate in the sciences; elsewhere the Sc.D. is a "higher doctorate" awarded in recognition of a substantial and sustained contribution to scientific knowledge beyond that required for a Doctor of Philosophy (PhD). Africa Algeria and Morocco In Algeria, Morocco, Libya and Tunisia, all universities accredited by the state award a "Doctorate" in all fields of science and humanities, equivalent to a PhD in the United Kingdom or United States. Some universities in these four Arab countries award a "Doctorate of the State" in some fields of study and science. A "Doctorate of the State" is slightly higher in esteem than a regular doctorate, and is awarded after performing additional in-depth post-doctorate research or ach ...
