Low’s Subleading Soft Theorem as a Symmetry of QED
V. Lysov, S. Pasterski and A. Strominger

It was shown by F. Low in the 1950s that the subleading terms of soft photon S-matrix elements obey a universal linear relation. In this paper we give a new interpretation to this old relation, for the case of massless QED, as an infinitesimal symmetry of the S-matrix.
July 31, 2014
Classical Interpretation of the Weinberg Soft Factor
Sabrina Gonzalez Pasterski

I show how the radiation emitted during the scattering of non-relativistic charged particles corresponds to the O(1/w) soft factor in QED.
(Origins of 'the Triangle' or: How I almost convinced Andy of the third vertex of 'the Triangle')
September 10, 2014
Generalizing the Soft Factor/Classical Connection
Sabrina Gonzalez Pasterski

I show that the polarization vector times the soft factor for a photon emitted in the xˆ direction is proportional to the time integral of the classical radiated electric field for the same scattering process, as measured by an observer sitting along that direction far away.

New Gravitational Memories
S. Pasterski, A. Strominger and A. Zhiboedov

We propose a new method for detecting gravitational waves:
a cumulative ‘spin memory effect’ in which beams on clockwise and counterclockwise orbits acquire a relative delay induced by radiative angular momentum flux.

Higher d Supertranslations and Weinberg's Soft Graviton Theorem
D. Kapec, V. Lysov, S. Pasterski and A. Strominger
