Generality across holographic nonequilibrium steady states

Determine whether the effective-temperature-dependent structure of critical phenomena observed at the current-driven tricritical point in the D3/D7 model also appears in other holographic nonequilibrium steady states.

Background

The study identifies a special role for a fixed effective-temperature-to-heat-bath-temperature path in recovering Landau-theory critical exponents at a current-driven tricritical point. It remains unresolved whether this structure is specific to the D3/D7 model or represents a broader feature of holographic nonequilibrium steady states. Comparative analyses of other holographic NESSs would test the generality of the observation.

References

Second, examining whether a similar structure appears in other holographic NESSs would clarify the generality of the present observation.
