Hace 3 días · Edward Witten; In the context of string theory, axions appear to provide the most plausible solution of the strong CP problem. However, as has been known for a long time, ...
Hace 2 días · These essential papers provided new methods which made the study of scattering amplitudes simpler and more efficient, culminating in the formulation of BCFW recursion relations by Witten and a group of IAS Members in the School of Natural Sciences at the time: Ruth Britto (2002–05, 2022–23), Freddy Cachazo (2002–05, 2009–10), and Bo Feng (2002–05).
Hace 3 días · 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.
Hace 3 días · Demanding this `axion species scale' not to exceed the gravitational species scale, we obtain the bound (8\pi^2/g^2)f \lesssim M_ {\rm Pl} (8π2/g2)f ≲ M Pl. This is quite similar to the axion weak gravity conjecture bound, but can be applied to any gauge as well as the string interactions which are relevant to towers of states.
Hace 3 días · "It's startling to see such a highly successful mathematician achieve success in another field," says Edward Witten, professor of physics at the Institute for Advanced Study in Princeton, New Jersey and considered by many of his peers to be the most accomplished theoretical physicist alive.
