Superrotations in Harmonic gauge

School
PARTICLES AND ACCELERATORS

Abstract: In this talk, I show how infinitesimal superrotations can be expressed, in harmonic gauge, in terms of metric components evaluated at the boundaries of null infinity that are subleading in a large radius expansion. Then I recast the spin memory observable in terms of these boundary values.
