On the underlying nonrelativistic nature of relativistic holography
摘要
Over the past quarter century, considerable effort has been invested in the study of nonrelativistic (NR) string theory, its U-dual NR brane theories, and their geometric foundations in (generalized) Newton-Cartan geometry. Many interesting results have been obtained, both for their intrinsic value and in the hope that they hold useful lessons for relativistic string/M theory. By synthesizing two strands of recent developments (especially, arXiv:2312.13243 and arXiv:2410.03591), we argue that this hope has already come to fruition, because standard, relativistic holography can now be recognized as a statement within a corresponding nonrelativistic brane theory. Our main conclusions are general, but in the familiar example of D3-brane based holography, they read as follows: (i)
