Holography and drag force in thermal plasma of non-commutative Yang-Mills theories in diverse dimensions

Understand

We use holography and a string probe approach to compute the drag force on a quark moving in a thermal plasma of non-commutative Yang-Mills (NCYM) theories in various dimensions.

• The gravity background in these cases are described by a particular decoupling limit of non-extremal (D$(p-2)$, D$p$) brane bound state system.
• We show how the drag force on an external quark moving in the dual NCYM theories gets corrected due to non-commutativity and as a result the effective viscosity of the plasma gets reduced.
• We have obtained the drag force for both small and large non-commutativity.
