Abstract

In this work, the effects of non-commutative and commutative vacua on the phase space generated by a scalar field in a scalar torsion scenario are investigated. For both classical and quantum regimes, the commutative and non-commutative cases are compared. To take account the effects of non-commutativity, two well known non-commutative parameters, θ\theta and β,\beta, are introduced. It should be emphasized, the effects of β\beta which is related to momentum sector has more key role in comparison to θ\theta which is related to space sector. Also the different boundary conditions and mathematical interpretations of non-commutativity are explored.
