Daya Shankar Kulshreshtha
Daya Shankar Kulshreshtha (born December, 1951) is an Indian theoretical physicist, specializing in formal aspects of quantum field theory, string theory, supersymmetry, supergravity and superstring theory, Dirac's instant-form and light-front quantization of field theories and D-brane actions. His work on the models of gravity focuses on the studies of charged compact boson stars and boson shells. Education and career Kulshreshtha obtained B.Sc. (1969) and M.Sc. (1971) degrees from Jiwaji University, Gwalior. He received his Ph.D. in 1979 from the University of Delhi, under the supervision of R. P. Saxena. He worked as a postdoctoral researcher at the University of Kaiserslautern (1982–1984). He then held a five-year position of a UGC-Research Scientist of the University Grants Commission of India at the University of Delhi (1986–1991) followed by a five-year position at the University of Kaiserslautern, Germany (1990–1994) before being appointed a professor at the ...

D-brane
In string theory, D-branes, short for ''Dirichlet membrane'', are a class of extended objects upon which open strings can end with Dirichlet boundary conditions, after which they are named. D-branes were discovered by Jin Dai, Leigh, and Polchinski, and independently by Hořava, in 1989. In 1995, Polchinski identified D-branes with black p-brane solutions of supergravity, a discovery that triggered the Second Superstring Revolution and led to both holographic and M-theory dualities. D-branes are typically classified by their spatial dimension, which is indicated by a number written after the ''D.'' A D0-brane is a single point, a D1-brane is a line (sometimes called a "D-string"), a D2-brane is a plane, and a D25-brane fills the highest-dimensional space considered in bosonic string theory. There are also instantonic D(–1)-branes, which are localized in both space and time. Theoretical background The equations of motion of string theory require that the endpoints of an o ...

Helvetica Physica Acta
Helvetica (originally Neue Haas Grotesk) is a widely used sans-serif typeface developed in 1957 by Swiss typeface designer Max Miedinger and Eduard Hoffmann. Helvetica is a neo-grotesque design, one influenced by the famous 19th century (1890s) typeface Akzidenz-Grotesk and other German and Swiss designs. Its use became a hallmark of the International Typographic Style that emerged from the work of Swiss designers in the 1950s and '60s, becoming one of the most popular typefaces of the mid-20th century. Over the years, a wide range of variants have been released in different weights, widths, and sizes, as well as matching designs for a range of non-Latin alphabets. Notable features of Helvetica as originally designed include a high x-height, the termination of strokes on horizontal or vertical lines and an unusually tight spacing between letters, which combine to give it a dense, solid appearance. Developed by the ''Haas'sche Schriftgiesserei'' (Haas Type Foundry) of Münchens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BRST Quantization
In theoretical physics, the BRST formalism, or BRST quantization (where the ''BRST'' refers to the last names of Carlo Becchi, , Raymond Stora and Igor Tyutin) denotes a relatively rigorous mathematical approach to Quantization (physics), quantizing a quantum field theory, field theory with a gauge symmetry. Quantization (physics), Quantization rules in earlier quantum field theory (QFT) frameworks resembled "prescriptions" or "heuristics" more than proofs, especially in non-abelian group, non-abelian QFT, where the use of "ghost fields" with superficially bizarre properties is almost unavoidable for technical reasons related to renormalization and anomaly cancellation. The BRST global supersymmetry introduced in the mid-1970s was quickly understood to rationalize the introduction of these Faddeev–Popov ghosts and their exclusion from "physical" asymptotic states when performing QFT calculations. Crucially, this symmetry of the path integral is preserved in loop order, and thu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Path Integral Formulation
The path integral formulation is a description in quantum mechanics that generalizes the action principle of classical mechanics. It replaces the classical notion of a single, unique classical trajectory for a system with a sum, or functional integral, over an infinity of quantum-mechanically possible trajectories to compute a quantum amplitude. This formulation has proven crucial to the subsequent development of theoretical physics, because manifest Lorentz covariance (time and space components of quantities enter equations in the same way) is easier to achieve than in the operator formalism of canonical quantization. Unlike previous methods, the path integral allows one to easily change coordinates between very different canonical descriptions of the same quantum system. Another advantage is that it is in practice easier to guess the correct form of the Lagrangian of a theory, which naturally enters the path integrals (for interactions of a certain type, these are ''coordinat ...

Proceedings Of Science
The International School for Advanced Studies (Italian: ''Scuola Internazionale Superiore di Studi Avanzati''; SISSA) is an international, state-supported, post-graduate-education and research institute in Trieste, Italy. SISSA is active in the fields of mathematics, physics and neuroscience, offering both undergraduate and post-graduate courses. Each year, about 70 PhD students are admitted to SISSA based on their scientific qualifications. SISSA also runs master's programs in the same areas, in collaboration with both Italian and other European universities. History SISSA was founded in 1978, as a part of the reconstruction following the Friuli earthquake of 1976. Although the city of Trieste itself did not suffer any damage, physicist Paolo Budinich asked and obtained from the Italian government to include in the interventions the institution of a new, post-graduate teaching and research institute, modeled on the Scuola Normale Superiore di Pisa. The school became operati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physics Letters B
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. ( ...

University Of Oldenburg
The Carl von Ossietzky University of Oldenburg (german: Carl von Ossietzky Universität Oldenburg) is a university located in Oldenburg, Germany. It is one of the most important and highly regarded educational facilities in northwestern Germany and specialises in interdisciplinary and sustainable development studies and renewable energy studies with focus on solar and wind energy. History The first teachers training was held in Oldenburg as early as 1793, launched by Duke Peter Friedrich Ludwig. A garden seminar for teachers training was created in 1882. During the Weimar Republic, the establishment of the ''Pedagogical Academy'' (Pädagogische Akademie) in Oldenburg in 1929 enabled the vocational training of teachers. On 1 October 1945, the institution reopened in postwar Germany. In 1948 it was renamed the ''Pedagogical College Oldenburg'' (Pädagogische Hochschule Oldenburg). The first step towards the university was taken on 23 February 1959 with the decision of the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
