Cosmological Particle Creation in the Presence of Lorentz Violation
E. Khajeh, N. Khosravi, H. Salehi
In recent years, the effects of Lorentz symmetry breaking in cosmology has attracted considerable amount of attention. In cosmological context several topics can be affected by Lor…
Unruh's detector in the presence of Lorentz symmetry breaking
R. Rashidi, N. Khosravi, E. Khajeh +1
We investigate the quantum field theory of a Lorentz non-invariant model with a massive nonlinear dispersion relation in Minkowski space. The model involves some non-causal signals…
Stabilization of internal space in noncommutative multidimensional cosmology
N. Khosravi, S. Jalalzadeh, H. R. Sepangi
We study the cosmological aspects of a noncommutative, multidimensional universe where the matter source is assumed to be a scalar field which does not commute with the internal sc…
Quantum noncommutative multidimensional cosmology
N. Khosravi, S. Jalalzadeh, H. R. Sepangi
We present exact quantum solutions for a noncommutative, multidimensional cosmological model and show that stabilization of extra dimensions sets in with the introduction of noncom…
Bianchi spacetimes in noncommutative phase-space
B. Vakili, N. Khosravi, H. R. Sepangi
The effects of noncommutativity in the phase-space of the classical and quantum cosmology of Bianchi models are investigated. Exact solutions in both commutative and noncommutative…
