J-P. Gazeau
Jean-Pierre Gazeau (born 10 October 1945) is a French physicist and mathematician who works in the field of symmetry in quantum physics. His research has focused on coherent states; beta numeration for quasicrystals, and more generally for aperiodic order; and de Sitter space and anti-de Sitter space times. He is a professor emeritus at Paris Diderot University, Sorbonne Paris Cité University (group).Through a career spanning 50 years, he has held research and teaching positions on five continents, with a particular concentration on developing and emerging countries. Education Gazeau graduated in applied mathematics from the University of Paris Faculty of Sciences in 1967. He earned his doctorate in science at the University Paris 6 (Pierre-et-Marie Curie) in 1978. Career Gazeau is the author ''"Coherent States in Quantum Physics"'' (2009). He is the co-author of ''"Coherent States, Wavelets and Their Generalizations"'', initially published in 2000 with a revised edition in 20 ...

Coherent States
In physics, specifically in quantum mechanics, a coherent state is the specific quantum state of the quantum harmonic oscillator, often described as a state which has dynamics most closely resembling the oscillatory behavior of a classical harmonic oscillator. It was the first example of quantum dynamics when Erwin Schrödinger derived it in 1926, while searching for solutions of the Schrödinger equation that satisfy the correspondence principle. The quantum harmonic oscillator (and hence the coherent states) arise in the quantum theory of a wide range of physical systems.J.R. Klauder and B. Skagerstam, ''Coherent States'', World Scientific, Singapore, 1985. For instance, a coherent state describes the oscillating motion of a particle confined in a quadratic potential well (for an early reference, see e.g. Schiff's textbook). The coherent state describes a state in a system for which the ground-state wavepacket is displaced from the origin of the system. This state can be relate ...

Pierre And Marie Curie University Faculty
Pierre is a masculine given name. It is a French form of the name Peter. Pierre originally meant "rock" or "stone" in French (derived from the Greek word πέτρος (''petros'') meaning "stone, rock", via Latin "petra"). It is a translation of Aramaic כיפא (''Kefa),'' the nickname Jesus gave to apostle Simon Bar-Jona, referred in English as Saint Peter. Pierre is also found as a surname. People with the given name * Abbé Pierre, Henri Marie Joseph Grouès (1912–2007), French Catholic priest who founded the Emmaus Movement * Monsieur Pierre, Pierre Jean Philippe Zurcher-Margolle (c. 1890–1963), French ballroom dancer and dance teacher * Pierre (footballer), Lucas Pierre Santos Oliveira (born 1982), Brazilian footballer * Pierre, Baron of Beauvau (c. 1380–1453) * Pierre, Duke of Penthièvre (1845–1919) * Pierre, marquis de Fayet (died 1737), French naval commander and Governor General of Saint-Domingue * Prince Pierre, Duke of Valentinois (1895–1964), father ...

University Of Paris Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

People From Lozère
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Sophie Toscan Du Plantier
Sophie Toscan du Plantier, a 39-year-old French woman, was killed outside her holiday home near Toormore, Goleen, County Cork, Ireland, on the night of 23 December 1996. British journalist Ian Bailey, who lived near Toscan du Plantier's home in Ireland, was a suspect arrested twice by the Garda Síochána, yet no charges were laid as the Director of Public Prosecutions (DPP) found there was insufficient evidence to proceed to trial. Bailey lost a libel case against six newspapers in 2003. He also lost a wrongful arrest case against the Gardaí, Minister for Justice, and Attorney General in 2015. In 2019, Bailey was convicted of murder by the ''Cour d'Assises'' in Paris, France, and sentenced to 25 years in prison. He was tried ''in absentia'' in France after winning a legal battle against extradition. In 2020, Ireland's High Court ruled that Bailey could not be extradited. Victim Sophie Toscan du Plantier, ''née'' Bouniol, a French television producer, lived in Paris with h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Sitter Space
In mathematical physics, ''n''-dimensional de Sitter space (often abbreviated to dS''n'') is a maximally symmetric Lorentzian manifold with constant positive scalar curvature. It is the Lorentzian analogue of an ''n''-sphere (with its canonical Riemannian metric). The main application of de Sitter space is its use in general relativity, where it serves as one of the simplest mathematical models of the universe consistent with the observed accelerating expansion of the universe. More specifically, de Sitter space is the maximally symmetric vacuum solution of Einstein's field equations with a positive cosmological constant \Lambda (corresponding to a positive vacuum energy density and negative pressure). There is cosmological evidence that the universe itself is asymptotically de Sitter, i.e. it will evolve like the de Sitter universe in the far future when dark energy dominates. de Sitter space and anti-de Sitter space are named after Willem de&nb ...
