Fermionic Backreaction on Quantum Spacetimes: Cosmological Implications
Y. Tavakoli, A. Khaleghi Ardabili, S. Mosaddegh
This article reviews a Hamiltonian framework for describing Dirac fermions propagating on quantum cosmological spacetimes within loop quantum cosmology. Expanding the fermionic fie…
Fermions in a loop quantum cosmological spacetime
Yaser Tavakoli, Ahad K. Ardabili, Sara Mosaddegh
We present a detailed Hamiltonian treatment of an inhomogeneous fermionic perturbation propagating on a closed FLRW spacetime quantized via LQC. Expanding the fermion in spinor har…
Role of Gauss-Bonnet corrections in a DGP brane gravitational collapse
Yaser Tavakoli, Ahad K. Ardabili, Mariam Bouhmadi-López +1
An Oppenheimer-Snyder (OS)-type collapse is considered for a Dvali-Gabadadze-Porrati (DGP) brane, whereas a Gauss-Bonnet (GB) term is provided for the bulk. We study the combined e…
Exploring the cosmic censorship conjecture with a Gauss-Bonnet sector
Yaser Tavakoli, Ahad K. Ardabili, Paulo Vargas Moniz
The Dvali-Gabadadze-Porrati (DGP) braneworld model is employed to study the gravitational collapse of dust, with a Gauss-Bonnet (GB) term present in the five-dimensional bulk. We f…
A tight binding model for quantum spin Hall effect on triangular optical lattice
Ahad K. Ardabili, Tekin Dereli, Özgür E. Müstecaplıoğlu
We propose a tight binding model for the quantum spin Hall system on triangular optical lattice and we determined the edge state spectrum which contains gap traversing states as th…
Z2 Topological insulator of ultra cold atoms in bichromatic optical lattices
Ahad K. Ardabili, Tekin Dereli, Özgür E. Müstecaplıoğlu
We investigate the effect of a strong bichromatic deformation to the topological insulator in a fermionic ultracold atomic system proposed by B. Béri and N. R. Coo…
