此论文标题：The existence of a minimum wavelength for photons
此文摘要：
The holographic property of entropy plays a key role in the thermodynamic description of gravita-
tional field equations. It remains unclear, we argue, whether this property is necessarily interwoven
with gravity itself or can be understood instead as a manifestation of physics outside gravity.
It is pointed out that if the latter is the case, so that the holographic property of entropy could be
considered as completely rooted on some microscopic, non-gravitational, intrinsic property of matter,
gravity could merely be understood as the necessary macroscopic manifestation of this microscopic
property of matter, being simply the expression of the thermodynamic conservation of energy. A
quite peculiar status of Einstein’s gravity in this context (as compared to generalized metric theories
of gravity) is apparent. A successful microscopic property of matter, is found to necessarily mean in
particular the existence of an absolute minimum wavelength for photons, of orders of Planck length.
