Center for Gravitation and Cosmology Seminars (2)


Topic:   Entanglement of Purification in Holographic Systems


Speaker: Dr. Peng Liu, Department of Physics, Jinan University


Time: 14:00, April 2, 2019


Venue: Physics Building 219


Abstract: The holographic entanglement of purification (EoP) in AdS4 and AdS-RN black hole backgrounds is studied. We develop an algorithm to compute the EoP for bipartite configuration with infinitely long strips. The temperature behavior of EoP is revealed for small, intermediate and large configurations: EoP monotonically increases with the temperature for small configurations; while for intermediate configurations, EoP is configuration-dependent; EoP vanishes for large configurations. Our numerical results verify some important inequalities of EoP, which we also prove geometrically in Poincare coordinate.


About Us

The Center for Gravitation and Cosmology (CGC) is a research center founded in 2017 at Yangzhou University, in the Jiangsu Province of China. It is an initiative of the BRICS-Association of Gravity and Cosmology, with support from the BRICS countries (Brazil, Russia, India, China and South Africa). The center is currently hosted on the 3rd floor of the College of Physical Sciences and Technology building, on the scenic Slender West Lake campus.
