Deformed phase space in a two dimensional minisuperspace model
H. R. Sepangi, B. Shakerin, B. Vakili
We study the effects of noncommutativity and deformed Heisenberg algebra on the evolution of a two dimensional minisuperspace cosmological model in classical and quantum regimes. T…

Cosmology with minimal length uncertainty relations
Babak Vakili
We study the effects of the existence of a minimal observable length in the phase space of classical and quantum de Sitter (dS) and Anti de Sitter (AdS) cosmology. Since this lengt…

Thermodynamics of noncommutative de Sitter spacetime
B. Vakili, N. Khosravi, H. R. Sepangi
We study the effects of noncommutativity of spacetime geometry on the thermodynamical properties of the de Sitter horizon. We show that noncommutativity results in modifications in…
