Python's Lunches in Jackiw-Teitelboim gravity with matter
Dongsu Bak, Chanju Kim, Sang-Heon Yi +1
We study Python's lunch geometries in the two-dimensional Jackiw-Teitelboim model coupled to a massless scalar field in the semiclassical limit. We show that all extrema including…
Complexity from Spinning Primaries
Robert de Mello Koch, Minkyoo Kim, Hendrik J. R. Van Zyl
We define circuits given by unitary representations of Lorentzian conformal field theory in 3 and 4 dimensions. Our circuits start from a spinning primary state, allowing us to gen…
Tests of Standard Cosmology in Horava Gravity and Bayesian Evidence for a Closed Universe, and the Hubble Tension
Nils A. Nilsson, Mu-In Park
We consider some background tests of standard cosmology in the context of Horava gravity with different scaling dimensions for space and time, which has been proposed as a renormal…
Engineering 3D theories using the quantum affine algebra
Jean-Emile Bourgine
The algebraic engineering technique is applied to a class of 3D gauge theories on the omega-deformed background . The vortex partition fun…
Identifying Riemannian singularities with regular non-Riemannian geometry
Kevin Morand, Jeong-Hyuck Park, Miok Park
Admitting non-Riemannian geometries, Double Field Theory extends the notion of spacetime beyond the Riemannian paradigm. We identify a class of singular spacetimes known in General…
Entanglement entropy of asymptotically flat non-extremal and extremal black holes with an island
Wontae Kim, Mungon Nam
The island rule for the entanglement entropy is applied to an eternal Reissner-Nordström black hole. The key ingredient is that the black hole is assumed to be in thermal equilibri…
