Hugh Osborn
Hugh Osborn is a British theoretical high-energy physicist and a professor emeritus at the University of Cambridge, Department of Applied Mathematics and Theoretical Physics. He is known for his work on Conformal Field Theory and Quantum Field Theory. Education Osborn obtained his PhD in 1967 from the University College London. His PhD advisor was Sigurd Zienau. Career and research After postdoctoral research positions at the University of Sussex and Queen Mary University of London, he became a professor first at the University of Glasgow and then in 1971 moved to the University of Cambridge where he remained ever since. He is a fellow of Trinity College. In April 2020 he was elected a Fellow of the Royal Society. In 1989, Osborn obtained the first proof of the four-dimensional C-theorem, which was conjectured one year earlier by John Cardy. Osborn's proof was applicable to renormalization group flows which are perturbative, that is do not deviate far from the free quantum f ...

Theoretical Physicist
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ian Jack (physicist)
Ian Grant Jack Fellow of the Royal Society of Literature, FRSL (7 February 1945 – 28 October 2022) was a British reporter, writer and editor. He edited the ''Independent on Sunday'', the literary magazine ''Granta'' and wrote regularly for ''The Guardian''. Early life Jack was born in Farnworth, Lancashire, on 7 February 1945, to parents who had migrated from Fife in 1930. Jack's mother, Isabella (née Gillespie), was born in Kirkcaldy and brought up in Hill of Beath, and his father Henry was born in Dunfermline. The family returned to Scotland when he was seven, in 1952. He grew up in North Queensferry and was educated there and at Dunfermline High School. Career After a false start as a would-be librarian, Jack joined ''The Glasgow Herald'' as a trainee journalist in 1965. After a short spell in its head office he was sent to work on two weekly papers in Lanarkshire, the now-defunct ''Cambuslang Advertiser'' and the ''East Kilbride News''.

University Of Würzburg
The Julius Maximilian University of Würzburg (also referred to as the University of Würzburg, in German ''Julius-Maximilians-Universität Würzburg'') is a public research university in Würzburg, Germany. The University of Würzburg is one of the oldest institutions of higher learning in Germany, having been founded in 1402. The university initially had a brief run and was closed in 1415. It was reopened in 1582 on the initiative of Julius Echter von Mespelbrunn. Today, the university is named for Julius Echter von Mespelbrunn and Maximilian Joseph. The University of Würzburg is part of the U15 group of research-intensive German universities. The university is also a member of the Coimbra Group. Name Its official name is Julius-Maximilians-Universität Würzburg (or "Julius-Maximilian University of Würzburg") but it is commonly referred to as the University of Würzburg.

Johanna Erdmenger
Johanna is a feminine name, a variant form of Joanna that originated in Latin in the Middle Ages, including an -h- by analogy with the Latin masculine name Johannes. The original Greek form ''Iōanna'' lacks a medial /h/ because in Greek /h/ could only occur initially. For more information on the name's origin, see the article on Joanna.

Conformal Field Theory
A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations. In two dimensions, there is an infinite-dimensional algebra of local conformal transformations, and conformal field theories can sometimes be exactly solved or classified. Conformal field theory has important applications to condensed matter physics, statistical mechanics, quantum statistical mechanics, and string theory. Statistical and condensed matter systems are indeed often conformally invariant at their thermodynamic or quantum critical points. Scale invariance vs conformal invariance In quantum field theory, scale invariance is a common and natural symmetry, because any fixed point of the renormalization group is by definition scale invariant. Conformal symmetry is stronger than scale invariance, and one needs additional assumptions to argue that it should appear in nature. The basic idea behind its plausibility is that ''local'' scale invariant theories have their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conformal Bootstrap
The conformal bootstrap is a non-perturbative mathematical method to constrain and solve conformal field theories, i.e. models of particle physics or statistical physics that exhibit similar properties at different levels of resolution. Overview Unlike more traditional techniques of quantum field theory, conformal bootstrap does not use the Lagrangian of the theory. Instead, it operates with the general axiomatic parameters, such as the scaling dimensions of the local operators and their operator product expansion coefficients. A key axiom is that the product of local operators must be expressible as a sum over local operators (thus turning the product into an algebra); the sum must have a non-zero radius of convergence. This leads to decompositions of correlation functions into structure constants and conformal blocks. The main ideas of the conformal bootstrap were formulated in the 1970s by the Soviet physicist Alexander Polyakov and the Italian physicists Sergio Ferrara, R ...

Adam Schwimmer
Adam; el, Ἀδάμ, Adám; la, Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, ''adam'' is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind". tells of God's creation of the world and its creatures, including ''adam'', meaning humankind; in God forms "Adam", this time meaning a single male human, out of "the dust of the ground", places him in the Garden of Eden, and forms a woman, Eve, as his helpmate; in Adam and Eve eat the fruit of the tree of knowledge and God condemns Adam to labour on the earth for his food and to return to it on his death; deals with the birth of Adam's sons, and lists his descendants from Seth to Noah. The Genesis creation myth was adopted by both Christianity and Islam, and the name of Adam accordingly appears in the Christian scriptures and in the Quran.
