Maurice A. de Gosson (born 13 March 1948), (also known as Maurice Alexis de Gosson de Varennes) is an Austrian mathematician and mathematical physicist, born in 1948 in Berlin. He is currently a Senior Researcher at the Numerical Harmonic Analysis Group (NuHAG) of the University of Vienna. After completing his PhD in microlocal analysis at the University of Nice in 1978 under the supervision of Jacques Chazarain, de Gosson soon became fascinated by Jean Leray's Lagrangian analysis. Under Leray's tutorship de Gosson completed a Habilitation à Diriger des Recherches en Mathématiques at the University of Paris 6 (1992). During this period he specialized in the study of the Leray–Maslov index and in the theory of the metaplectic group, and their applications to mathematical physics. In 1998 de Gosson met Basil Hiley, who triggered his interest in conceptual question in quantum mechanics. Basil Hiley wrote a foreword to de Gosson's book The Principles of Newtonian and Quantum Mechanics (Imperial College Press, London). After having spent several years in Sweden as Associate Professor and Professor in Sweden, de Gosson was appointed in 2006 at the Numerical Harmonic Analysis Group of the University of Vienna, created by Hans Georg Feichtinger (see www.nuhag.eu). He currently works in symplectic methods in harmonic analysis, and on conceptual questions in quantum mechanics, often in collaboration with Basil Hiley. Maurice de Gosson has held longer visiting positions at Yale University , University of Colorado in Boulder (Ulam Visiting Professor) , University of Potsdam, Albert-Einstein-Institut (Golm), Max-Planck-Institut für Mathematik (Bonn), Université Paul Sabatier (Toulouse), Jacobs Universität (Bremen) Maurice de Gosson was the first to prove that Mikhail Gromov's symplectic non-squeezing theorem (also called „the Principle of the Symplectic Camel“) allowed the derivation of a classical uncertainty principle formally totally similar to the Robertson–Schrödinger uncertainty relations (i.e. the Heisenberg inequalities in a stronger form where the covariances are taken into account). This rather unexpected result was discussed in the media. In 2004/2005, de Gosson showed that Gromov's non-squeezing theorem allows a coarse graining of phase space by symplectic quantum cells, each described by a mean momentum and a mean position. The cell is invariant under canonical transformations. De Gosson called such a quantum cell a quantum blob: "The quantum blob is the image of a phase space ball with radius by a (linear) symplectic transformation" and “Quantum blobs are the smallest phase space units of phase space compatible with the uncertainty principle of quantum mechanics and having the symplectic group as group of symmetries. Quantum blobs are in a bijective correspondence with the squeezed coherent states from standard quantum mechanics, of which they are a phase space picture.” Their invariance property distinguishes de Gosson's quantum blobs from the "quantum cells" known in thermodynamics, which are units of phase space with a volume of the size of Planck's constant h to the power of 3. De Gosson's notion of quantum blobs has given rise to a proposal for a new formulation of quantum mechanics, which is derived from postulates on quantum-blob-related limits to the extent and localization of quantum particles in phase space; this proposal is strengthened by the development of a phase space approach that applies to both quantum and classical physics, where a quantum-like evolution law for observables can be recovered from the classical Hamiltonian in a non-commutative phase space, where x and p are (non-commutative) c-numbers, not operators.
Yves Couder travaille au Laboratoire Matière et Systèmes complexes de l’Université Paris Diderot. Après une formation en physique de la matière condensée, il s’est orienté vers la physique non-linéaire sous ses aspects divers ; chaos spatio-temporel, turbulence en 2 et 3 dimensions et morphogénèse. Dans ce dernier domaine il s’est intéressé aux formes résultant de la croissance soit dans divers systèmes physiques, soit en biologie végétale. Ses travaux récents sont consacrés à la dualité onde-particule à l’échelle macroscopique.

Stephen Adler (b. 1939 in New York City) is an American physicist specializing in elementary particles and field theory. He received an A.B. degree at Harvard University in 1961 and a Ph.D. from Princeton University in 1964. He became a member of the Institute for Advanced Study in 1966, becoming a full Professor of Theoretical Physics in 1969, and was named "New Jersey Albert Einstein Professor" at the institute in 1979.
