We show that the soft part of the charge generating 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. We then recast the spin memory observable in terms of these boundary values.

  1. Gravitational memory and Ward identities in the local detector frame

    gr-qc 2024-12 conditional novelty 6.0 of 10

    Gravitational memory in TT gauge is encoded in large residual diffeomorphisms that equal BMS transformations, and their Ward identities yield soft graviton theorems and flat-space consistency relations.

  2. Gravitational memory and soft theorems: The local perspective

    gr-qc 2024-12 conditional novelty 6.0 of 10

    Gravitational memory is shown to be a large residual coordinate transformation in TT gauge, yielding new flat-space soft theorems for equal-time correlators that mirror inflationary consistency relations.
