Degenerate Limits of Scalar-Tensor Gravity
Bekir Baytaş, Xiao-Kan Guo
We study the degenerate limits of the scalar-tensor theory of gravity in its Hamiltonian connection dynamics formulation. The degenerate limit of the spatial triad is effectuated b…
Observational Constraints on Emergent Fractional Fractal Cosmology
Raheleh Jalalzadeh, Hooman Moradpour, Shahram Jalalzadeh
We constrain the Emergent Fractional Fractal (EFF) cosmological model through a joint likelihood analysis of recent cosmological observations at the background and perturbation lev…
Finite Hilbert space and maximum mass of Schwarzschild black holes from a Generalized Uncertainty Principle
S. Jalalzadeh, H. Moradpour
We show that implementing a generalized uncertainty principle (GUP) with both minimal length and maximal momentum directly on the reduced phase space of the Schwarzschild black hol…
Constraining fractionality using some observational tests
H. Moradpour, S. Jalalzadeh, R. Jalalzadeh +1
Recently, a fractional version of the Schwarzschild-Tangherlini black hole with a fractal horizon has been introduced. Motivated by the key role of the Schwarzschild solution in gr…
A class of entangled and diffeomorphism-invariant states in loop quantum gravity: Bell-network states
Bekir Baytaş
Bell-network states constitute a class of diffeomorphism-invariant and entangled states of the geometry within loop quantum gravity (LQG) that satisfy an area-law for the entanglem…
Effective geometry of Bell-network states on a dipole graph
Bekir Baytaş, Nelson Yokomizo
Bell-network states are a class of entangled states of the geometry that satisfy an area-law for the entanglement entropy in a limit of large spins and are automorphism-invariant,…
