Canonical quantization of all minisuperspaces with consistent symmetry reductions
Poula Tadros, Ivan KoláÅ, Otakar SvÃtek
We present the quantization of all symmetry reductions of the Einstein--Hilbert Lagrangian that correctly reproduce the reduced Einstein's field equations -- i.e., characterized by…
New Rotating Black Holes in String Theory
Watse Sybesma, Poula Tadros
We present new black hole solutions to the low-energy effective action of string theory. We introduce three- and four-dimensional solutions that are rotating, asymptotically flat,…
Carroll black holes in (A)dS and their higher-derivative modifications
Poula Tadros, Ivan KoláÅ
We define the Carrollian black holes corresponding to the limit of Schwarzschild-(A)dS spacetime and its higher-derivative counterpart known as Schwarzschild-Bach-(A)dS spacetime,…
Uniqueness of Galilean and Carrollian limits of gravitational theories and application to higher derivative gravity
Poula Tadros, Ivan KoláÅ
We show that the seemingly different methods used to derive non-Lorentzian (Galilean and Carrollian) gravitational theories from Lorentzian ones are equivalent. Specifically, the p…
Carrollian limit of quadratic gravity
Poula Tadros, Ivan KoláÅ
We study the Carrollian limit of the (general) quadratic gravity in four dimensions. We find that in order for the Carrollian theory to be a modification of the Carrollian limit of…
Rotating Carroll Black Holes: A No Go Theorem
Ivan KoláÅ, David Kubiznak, Poula Tadros
Recently, there has been a lot of interest in Carroll black holes and in particular whether or not one could find a Carrollian analogue of a rotating black hole spacetime. Here we…
