Publication High temperature behavior of non-local observables in boosted strongly coupled plasma: a holographic study(Springer Science and Business Media LLC, 2020-07) Atanu Bhatta; Shankhadeep Chakrabortty; Suat Dengiz; Ercan KilicarslanAbstractIn this work, we perform a holographic analysis to study non local observables associated to a uniformly boosted strongly coupled large N thermal plasma in d-dimensions. In order to accomplish the holographic analysis, the appropriate dual bulk theory turns out to be $$d+1$$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.Publication Impulsive waves in ghost-free infinite derivative gravity in anti–de Sitter spacetime(American Physical Society (APS), 2020-08-07) Suat Dengiz; Ercan Kilicarslan; Ivan Kolář; Anupam MazumdarPublication Lee-Wald charge and asymptotic behaviors of the Weyl-invariant topologically massive gravity(IOP Publishing, 2020-10-14) Suat Dengiz; Ercan Kilicarslan; M Reza SetareAbstract We apply the Lee–Wald covariant phase space method to the Weyl-invariant topologically massive gravity and compute the corresponding on-shell conserved charges. By using appropriate decay conditions for the existing propagating modes in the near-horizon of a stationary black hole, we obtain the charges generating the asymptotic symmetries. We show that the charges are integrable and the (modified) algebras among the asymptotic generators are closed for the certain choice of central extensions.Publication New chiral generalized minimal massive gravity(American Physical Society (APS), 2021-09-02) Mohammad Reza Setare; Seyed Naseh Sajadi; Suat Dengiz; Ercan KilicarslanPublication Exact gyratons in higher and infinite derivative gravity(American Physical Society (APS), 2022-02-11) Ivan Kolář; Tomáš Málek; Suat Dengiz; Ercan Kilicarslan
