Abstract:
In this work, we perform a holographic analysis to study non local observables associated to a uniformly
boosted strongly coupled large N thermal plasma in ddimensions. In order to accomplish the holographic analysis,
the appropriate dual bulk theory turns out to be d +1 dimensional boosted AdS-Schwarzschild blackhole background. In
particular, we compute entanglement entropy of the boosted
plasma at high temperature living inside a strip geometry with
entangling width l in the boundary at a particular instant of
time. We also study the two-point correlators in the boundary
by following geodesic approximation method. For analyzing
the effect of boosting on the thermal plasma and correspondingly on both non local observables, we keep the alignment of
the width of region of interest both parallel and perpendicular
to the direction of the boost. We find our results significantly
modified compared to those in un-boosted plasma up to the
quadratic order of the boost velocity v. More interestingly,
the relative orientation of the boost and the entangling width
play a crucial role to quantify the holographic entanglement
entropy in the boundary theory. The breaking of rotational
symmetry in the boundary theory due to the boosting of the
plasma along a specific flat direction causes this interesting
feature.
