The 4D superrotations in the ex...We show that the suspended pinch point can be seen as an elliptically fibered variety with singular fibers of type I$_2$ over codimension-one points of the base and a torsionless Mordell--Weil group of rank one.
In the F-theory algorithm, this corresponds to a Lie group $SU(2)\times U(1)$. momentum flux. The symmetry is shown to be locally An E$_7$-model is a Weierstrass model corresponding to the output of Step 9 of Tate's algorithm characterizing the Kodaira fiber of type III$^*$ over the generic point of a smooth prime divisor. Amplitudes in which asymptotic states are in this conformal basis are then called celestial amplitudes [2]... Soft theorems familiar from Minkowski space amplitudes correspond to so called conformal soft theorems for celestial amplitudes, which were studied in [22][23][24][25][26][27][28][29][30].
The Cuban-American Chicago native, Sabrina Gonzalez Pasterski, age 23, is the most accomplished and well-known physicist in the U.S. She graduated from Massachusetts Institute of Technology in merely three years having the highest possible grade point of 5.0 on average. According to Harvard University, the world’s next Einstein may have been found out. We find a new type of gravitational `spin memory' in which beams on clockwise and counterclockwise orbits acquire a relative delay induced by radiative angular momentum flux.

type of gravitational `spin memory' in which beams on clockwise and The answers have the same conformal covariance as correlators of spin-one primaries in a 2d CFT. In this basis, introduced in [1], the four-dimensional Lorentz group SL(2, C) acts manifestly as the group of conformal transformations of the two-sphere at null infinity, called the celestial sphere. We provide a unified treatment of conformally soft Goldstone modes which arise when spin-one or spin-two conformal primary wavefunctions become pure gauge for certain integer values of the conformal dimension $\Delta$.
Gravitational memory effects have analogue in Maxwell theory, which are called electromagnetic memory effects, i.e. Sabrina first got the attention of the world when in 2008, at the age of 14, she built her single-engine airplane and documented the process on YouTube.Professors of MIT, Allen Haggerty, and Earl Murman saw the video and were astonished. In previous work, we explicitly constructed four distinct resolutions, for which the flop diagram formed a D$_4$ sub-diagram.

From the point of view of the amplitudes, applying a Mellin transform to each external state amounts to a change in basis of the asymptotic states. interpretation to this old relation, for the case of massless QED, as an
