Area density of localization-entropy

چکیده

Using the holographic lightfront projection, which in the present context is not an independent principle but a consequence of the properties underlying the algebraic formulation of QFT, we derive an area law for the localization-entropy caused by vacuum polarization. Its area density is equal to the localization entropy of an associated auxiliary chiral theory. Its microscopic derivation with the help of angular Euclideanization in the standard setting of statistical mechanics leads to a universal linear divergence multiplied with a strength which only depends on the quantum matter content of the holographic projection. This ultraviolet divergence is conformally equivalent to the missing one-dimensional length factor which together with the area yield a 3-dimensional volume factor. However we do not know whether this close analogy with standard heat bath entropy also holds for the thermodynamic laws, i.e. the validity of a normalizing thermodynamic fundamental law for vacuum polarizationinduced entropy remains open. Whereas the localizationand black holeentropy share the area proportionality, the residual dependence of the former on the holographic quantum matter content poses an interesting (and hopefully enigmatic) contrast to the Bekenstein area law whose resolution may encode aspects of the still elusive quantum gravity.

Area density of localization-entropy I: the case of wedge-localization

Using an appropriatly formulated holographic lightfront projection, we derive an area law for the localization-entropy caused by vacuum polarization on the horizon of a wedge region. Its area density has a simple kinematic relation to the volume extensive heat bath entropy of the lightfront algebra. Apart from a change of parametrization the infinite lighlike length contribution to the lightfro...

Lightfront holography and area density of entropy associated with localization on wedge-horizons

It is shown that a suitably formulated algebraic lightfront holography (LFH), in which the lightfront is viewed as the linear extension of the upper causal horizon of a wedge region, is capable of overcoming the shortcomings of the old lightfront quantization. The absence of transverse vacuum fluctuations which this formalism reveals is responsible for an area (edge of the wedge) -rearrangement...
