Longitudinal electric corner modes in continuum quantum gauge theory with matter
Goncalo Araujo-Regado, Philipp A. Hoehn, Alok Laddha +1
Subregions in gauge theories give rise to edge modes and corner charges supported on their boundaries. While this is well-established classically and in quantum lattice gauge theor…
Holographic Cosmology at Finite Time
Goncalo Araujo-Regado, Ayngaran Thavanesan, Aron C. Wall
We investigate Cauchy Slice Holography in de Sitter spacetime. By performing a deformation of a (bottom-up) dS/CFT model, we obtain a holographic theory living on flat Cauchy…
Relational entanglement entropies and quantum reference frames in gauge theories
Goncalo Araujo-Regado, Philipp A. Hoehn, Francesco Sartini
It has been shown that defining gravitational entanglement entropies relative to quantum reference frames (QRFs) intrinsically regularizes them. Here, we demonstrate that such rela…
Soft edges: the many links between soft and edge modes
Goncalo Araujo-Regado, Philipp A. Hoehn, Francesco Sartini +1
Boundaries in gauge theory and gravity give rise to symmetries and charges at both finite and asymptotic distance. Due to their structural similarities, it is often held that soft…
Holographic Cosmology on Closed Slices in 2+1 Dimensions
Goncalo Araujo-Regado
We apply the framework of Cauchy Slice Holography to the quantization of gravity on closed slices with (with a focus on dimensions for concreteness). We obtain solution…
Cauchy Slice Holography: A New AdS/CFT Dictionary
Goncalo Araujo-Regado, Rifath Khan, Aron C. Wall
We investigate a new approach to holography in asymptotically AdS spacetimes, in which time rather than space is the emergent dimension. By making a sufficiently large T^2-deformat…
