Ultra slow-turn inflation
Ana Achúcarro, Perseas Christodoulidis, Jinn-Ouk Gong +1
In standard multi-field models, tachyonic isocurvature perturbations generally indicate the presence of an instability. We revisit the stability of some known counterexamples and s…
Entropic order parameters and topological holography
Hua-Chen Zhang, Germán Sierra, Javier Molina-Vilaplana
We show that the symmetry topological field theory (SymTFT) construction, also known as the topological holography, provides a natural and intuitive framework for the entropic orde…
Traversable wormhole with double trace deformations via gravitational shear and sound channels
Fitria Khairunnisa, Hadyan Luthfan Prihadi, M. Zhahir Djogama +2
We investigate how non-local gravitational couplings from double trace deformation between two asymptotic boundaries of an AdS black brane can lead to the violation of the Aver…
Toward Krylov-based holography in double-scaled SYK
Yichao Fu, Hyun-Sik Jeong, Keun-Young Kim +1
Building on the duality between Krylov complexity and geodesic length in Jackiw-Teitelboim and sine-dilaton gravity, we develop a precise holographic dictionary for quantities in t…
An analytic approach for holographic entanglement entropy at (quantum) criticality
Parul Jain, Matti Järvinen
We consider holographic entanglement entropy in AdS black hole backgrounds by using the limit of large number of dimensions. By dividing the geometry to two patches (with one patch…
-term Multi-Field Inflation in Supergravity without Stabiliser Superfields
Jinn-Ouk Gong, Sergei V. Ketov, Takahiro Terada
Realising -term slow-roll inflation in supergravity is non-trivial due to the well-known -problem. The common strategy to solve the problem is to impose a shift symmetry on t…
