An Algebra of Observables for de Sitter Space
Keiichiro Furuya (Purdue University)
Abstract: In this talk, I will review the latest paper, ``An Algebra of Observables for de Sitter Space’’. Since Bekenstein studied the entropy associated with the black hole, the studies of the entropic structure of a system with gravity have been developed. Especially, the (entanglement) entropy of a quantum system of two different regions is important to explore the correlations in a system. In a quantum mechanical system, the (entanglement) entropy is a property of the states of a given system. In quantum field theory, it is instead the property of the algebra of quantum field theory associated with a subregion of spacetime, which we now call the local algebra. In particular, the ultraviolet divergence is due to the property of the local algebra. Hence, understanding the entropic structure of quantum field theory requires you to investigate the structure of a local algebra. This paper specifies the properties of the local algebra of quantum field theory in de Sitter space to seek its entropy.
