Stability and Chaotic Dynamics in a Nonlinearly Confined ghost-sector Hamiltonian
Zahra Molaee, Soleyman Fatholahzadeh
We investigate the nonlinear dynamics of a Hamiltonian system containing a ghost degree of freedom coupled to a canonical sector through nonlinear interactions. The model consists…
Generators of Local Lorentz Transformation in ADM-Vielbein Formalism of Gravitational Relativity
Alireza Faraji, Zahra Molaee, Ahmad Shirzad
General relativity contains 16 variables in the framework of ADM-Vielbein formalism which are 6 more than metric formalism. These variables emerge due to additional symmetry of Loc…
Constraint structure of the Generalized Proca model in the Lagrangian formalism
Zahra Molaee, Ahmad Shirzad
We present a new Lagrangian approach for the dynamical structure of the generalized Proca theory (GP). This approach includes the A-Z constraint structure of the model in the Lagra…
Multi-field Cuscuton Cosmology
Seyed Ali Hosseini Mansoori, Zahra Molaee
In this paper, we first introduce a multi-field setup of Cuscuton gravity in a curved field space manifold. Then, we show that this model allows for a regular bouncing cosmology an…
Multi-field Mimetic Gravity
Seyed Ali Hosseini Mansoori, Alireza Talebian, Zahra Molaee +1
In this paper, we extend the mimetic gravity to the multi-field setup with a curved field space manifold. The multi-field mimetic scenario is realized via the singular limit of the…
Gauge generator for bi-gravity and multi-gravity models
Ali Dokhani, Zahra Molaee, Ahmad Shirzad
Following the Hamiltonian structure of bi-gravity and multi-gravity models in the full phase space, we have constructed the generating functional of diffeomorphism gauge symmetry.…
Hamiltonian formalism of the ghost free Tri(-Multi)gravity theory
Zahra Molaee, Ahmad Shirzad
We study the Hamiltonian structure of tri-gravity and four-gravity in the framework of ADM decomposition of the corresponding metrics. Hence we can deduce the general structure of…
Hamiltonian structure of bi-gravity, problem of ghost and bifurcation
Zahra Molaee, Ahmad Shirzad
We analyze the Hamiltonian structure of a general theory of bi-gravity where the interaction term is a scalar function of the form where may…
Massive gravity, canonical structure and gauge symmetry
Zahra Molaee, Ahmad Shirzad
Performing Hamiltonian analysis of the massive gravity [9] in full phase space, we see that the theory is ghost free. We also see in a more clear way that this result is intrinsic…
On Remarks on the spin-one Duffin-Kemmer-Petiau equation in the presence of nonminimal vector interactions in (3+1) dimensions
H. Hassanabadi, Z. Molaee, M. Ghominejad +1
In a very recent manuscript [arXiv:1403.6035], Castro and Oliveira have commented on our recently published paper [2]. Their main criticism is that we have used an improper nonmini…
