Frame dependence of anisotropy in other holographic nonlocal observables

Determine whether the frame-dependent anisotropy found for Wilson-loop observables in the equal-rotation Myers–Perry holographic plasma persists for other nonlocal probes, specifically the Schwinger effect and entanglement observables, when analyzed in both static and corotating descriptions.

Background

The paper compares Wilson-loop observables for heavy quark–antiquark pairs held fixed in a static frame and in a frame corotating with an equal-rotation Myers–Perry plasma. It finds that the corotating description exhibits substantially stronger orientation dependence: longitudinal and transverse separations and maximal separations respond qualitatively differently to angular velocity, whereas the corresponding static-frame quantities are both suppressed.

The authors propose extending this comparison beyond Wilson loops to other nonlocal holographic probes. The unresolved issue is whether the pronounced dependence on the observer frame and the associated anisotropy are specific to heavy-quark observables or represent a more general feature of nonlocal probes in rotating holographic systems.

References

A natural next step is to investigate other nonlocal probes, such as the Schwinger effect and entanglement observables, in the same static and corotating descriptions, and to determine whether the frame-dependent anisotropy found here persists.
