Abstract In holographic theories. the Hubeny-Rangamani-Takayanagi (HRT) area operator plays a key role in our understanding of the emergence of semiclassical Einstein-Hilbert gravity. When higher derivative corrections are included. the role of the area is instead played by a more general functional known as the geometric entropy. https://www.marcelovicente.com/product-category/angel-light-hold-gel/
