Roger Balian (born 18 January 1933) is a French-Armenian physicist who has worked on quantum field theory, quantum thermodynamics, and theory of measurement. [1] Balian is a member of the French Academy of Sciences. [2] His important works include the Balian-Low theorem. He teaches statistical physics at the École polytechnique. [3]
Baron Augustin-Louis Cauchy was a French mathematician, engineer, and physicist. He was one of the first to rigorously state and prove the key theorems of calculus, pioneered the field complex analysis, and the study of permutation groups in abstract algebra. Cauchy also contributed to a number of topics in mathematical physics, notably continuum mechanics.
Baron Siméon Denis Poisson FRS FRSE was a French mathematician and physicist who worked on statistics, complex analysis, partial differential equations, the calculus of variations, analytical mechanics, electricity and magnetism, thermodynamics, elasticity, and fluid mechanics. Moreover, he predicted the Arago spot in his attempt to disprove the wave theory of Augustin-Jean Fresnel.
Louis Victor Pierre Raymond, 7th Duc de Broglie was a French physicist and aristocrat who made groundbreaking contributions to quantum theory. In his 1924 PhD thesis, he postulated the wave nature of electrons and suggested that all matter has wave properties. This concept is known as the de Broglie hypothesis, an example of wave-particle duality, and forms a central part of the theory of quantum mechanics.
Jean-Victor Poncelet was a French engineer and mathematician who served most notably as the Commanding General of the École Polytechnique. He is considered a reviver of projective geometry, and his work Traité des propriétés projectives des figures is considered the first definitive text on the subject since Gérard Desargues' work on it in the 17th century. He later wrote an introduction to it: Applications d'analyse et de géométrie.
Jacques Charles François Sturm was a French mathematician, who made a significant addition to equation theory with his work, Sturm's theorem.
Alain Aspect is a French physicist noted for his experimental work on quantum entanglement.
Bernard d'Espagnat was a French theoretical physicist, philosopher of science, and author, best known for his work on the nature of reality. The Wigner–d'Espagnat inequality is partially named after him.
Michel Bitbol is a French researcher in philosophy of science.
Claude Burdin was a French engineer. Born in Lépin-le-Lac, Savoie, when it was known as the Duchy of Savoy, he was professor at the school of mines, École nationale supérieure des mines de Saint-Étienne, in Saint-Étienne. He became a French citizen on 4 June 1817. He proposed the concept and developed the term turbine from the Greek word τύρβη, meaning "whirling" or a "vortex".
Jean-Baptiste Joseph Fourier was a French mathematician and physicist born in Auxerre and best known for initiating the investigation of Fourier series, which eventually developed into Fourier analysis and harmonic analysis, and their applications to problems of heat transfer and vibrations. The Fourier transform and Fourier's law of conduction are also named in his honour. Fourier is also generally credited with the discovery of the greenhouse effect.
The Institut Polytechnique des Sciences Avancées (IPSA), is a French private grande école in aerospace engineering located at Ivry-sur-Seine, Lyon and Toulouse, recognized by the French state since 2010, whose diploma has been accredited by the French Commission des Titres d'Ingénieur since 2011. It was founded in 1961 and has been part of IONIS Education Group since 1998.
Jean Zinn-Justin is a French theoretical physicist.
Marcel Boll was a French scientist, sociologist, philosopher, educator, scientific journalist, and a founding member (1930) of the Rationalist Union. Boll was one of the most prolific contributors of articles to Les Cahiers Rationalistes and Raison Présente, two journals published by the Rationalist Union. He was one of the main popularizers of the theory of relativity, the quantum theory, and other aspects of the physical sciences during the interwar period (1918-1939) and in the early 1950s. An advocate of neopositivism, his numerous works on physics, philosophy, sociology, education, and other subjects all reflect his neopositivist perspective. He was the first person to draw the French public's attention to the Vienna Circle. Louis Rougier (1889-1982) and Général Charles-Ernest Vouillemin (1865-1954) later joined Boll in being among the first to introduce and promote the Vienna Circle and its overall philosophical outlook in France.
Jean-Michel Bony is a French mathematician, specializing in mathematical analysis. He is known for his work on microlocal analysis and pseudodifferential operators.
Jean-Pierre Dupuy is a French engineer and philosopher.
Claude Georges Itzykson, was a French theoretical physicist who worked in quantum field theory and statistical mechanics.
Daniel Kaplan is a French condensed matter physicist whose main work concerns the electronic properties of semiconductors, magnetic resonance and ultra-short pulse lasers. He is a member of the French Academy of Sciences.
Michel Spiro is a French physicist.
Jean-Paul Poirier is a French physicist and member of the French Academy of Sciences.
The Institute of Theoretical Physics (IPhT) is a research institute of the Direction of Fundamental Research (DRF) of the French Alternative Energies and Atomic Energy Commission (CEA). The Institute is also a joint research unit of the Institute of Physics (INP), a subsidiary of the French National Center for Scientific Research (CNRS). It is associated to the Paris-Saclay University. IPhT is situated on the Saclay Plateau South of Paris.
