Reduced State Uniquely Defines Groverian Measure of Original Pure State
Eylee Jung, Mi-Ra Hwang, Hungsoo Kim +4
Groverian and Geometric entanglement measures of the n-party pure state are expressed by the (n-1)-party reduced state density operator directly. This main theorem derives several…

Holographic energy density in the Brans-Dicke teory
Hungsoo Kim, H. W. Lee, Y. S. Myung
We study cosmological applications of the holographic energy density. Considering the holographic energy density as a dynamical cosmological constant, we need the Brans-Dicke theor…
