Canonical quantization of all minisuperspaces with consistent symmetry reductions
Poula Tadros, Ivan Kolář, Otakar Svítek
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,…
Rotating Carroll Black Holes: A No Go Theorem
Ivan Kolář, 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…
Intrinsically-defined higher-derivative Carrollian scalar field theories without Ostrogradsky instability
Poula Tadros, Ivan Kolář
We derive the most generic Carrollian higher derivative free scalar field theory intrinsically on a Carrollian manifold. The solutions to these theories are massless free particles…
Carroll black holes in (A)dS and their higher-derivative modifications
Poula Tadros, Ivan Kolář
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 Kolář
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 Kolář
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…
Signatures of many-body localization of quasiparticles in a flat band superconductor
Koushik Swaminathan, Poula Tadros, Sebastiano Peotta
We construct a class of exact eigenstates of the Hamiltonian obtained by projecting the Hubbard interaction term onto the flat band subspace of a generic lattice model. These exact…
Fields and strings on non commutative q-deformed spaces
Poula Tadros
We study scalar field and string theory on non commutative q-deformed spaces. We define a product of functions on a non commutative algebra of functions resulting from the q-deform…
(1+1) dimensional scalar field theory on q-deformed space
Poula Tadros
We study scalar field theory in one space and one time dimensions on a q-deformed space with static background. We write the Lagrangian and the equation of motion and solve it to t…
Low energy models of string theory
Poula Tadros, Iiro Vilja
String theory is the prime candidate for the theory of everything. However, it must be defined in ten dimensions to be consistent. To get 4D physics, the 6 other dimensions should…
Non relativistic string compactifications on Calabi-Yau manifolds
Poula Tadros, Iiro Vilja
We study Calabi-Yau compactifications of non relativistic string theory and show that it can be derived from the corresponding relativistic Calabi-Yau compactifications by taking t…
Eliminating black holes singularity in Brane world Cosmology
Poula Tadros, Mohamed Assaad Abdel-Raouf
In recent works, a construction was proposed resulting emergent universes inside black holes. This result can be obtained from a 4D black hole embedded in a 5D space time with the…
On models of Cosmology
Poula Tadros, Mohamed Assaad Abdel-Raouf
In this work the most promising string cosmology models are re-viewed model by model in detail. These models are based on conceptsform string theory and heterotic M theory to const…
