1 giorno fa · Il fisico Edward Witten fu il primo a ipotizzare la Teoria M nel 1995, fondendo la string theory “classica” con quella della supergravità a undici dimensioni: e di supergravità sembra parlare da subito il film di Francis Ford Coppola, con l’incipit in cui Catilina è sospeso ad un passo dal vuoto sul tetto di un edificio che somiglia al Chrysler Building di New York, solo che la città ...
4 giorni fa · In string theory, it was discovered in 1985 by Philip Candelas, Gary Horowitz, Andrew Strominger, and Edward Witten that these Calabi–Yau manifolds, due to their special holonomy, are the appropriate configuration spaces for superstrings.
2 giorni fa · Hawking with string theorists David Gross and Edward Witten at the Strings Conference in January 2001, TIFR, India. Hawking pursued his work in physics: in 1993 he co-edited a book on Euclidean quantum gravity with Gary Gibbons and published a collected edition of his own articles on black holes and the Big Bang.

2 giorni fa · We consider a bulk plus boundary extension of Jackiw-Teitelboim Gravity (JT) coupled with Yang-Mills fields. The generalization is performed in the Poisson Sigma Model formulation. We discuss the role of boundary conditions in relation to the symmetries of the boundary dynamics and we show that the boundary action can be written in terms of ...
4 giorni fa · In this work we have considered the cosmological dynamics of a scalar field with an axion like potential, in the background of non-standard spacetime metric. The metric we considered was in general that of a inhomogeneous and anisotropic spacetime, which in the far observer limit reduced to the case of a standard Kantowski-Sachs metric.

2 giorni fa · Edward Witten is an American theoretical physicist born on August 26, 1951, in Baltimore, Maryland. He is known for his contributions to string theory, quantum field theory, and mathematics. Witten's work has earned him numerous accolades, including the prestigious Fields Medal in 1990, which is often regarded as the highest honor a mathematician can receive.
