A Note on Entanglement Entropy for Primary Fermion Fields in JT Gravity

Chang-Zhong Guo, Wen-Cong Gan, Fu-Wen Shu

In this paper we analyse and discuss 2D Jackiw-Teitelboim (JT) gravity coupled to primary fermion fields in asymptotically anti-de Sitter (AdS) spacetimes. We get a particular solu…

A braneworld model in a massive gravity

Ke Yang, Shi-Fa Guo, Bao-Min Gu

A Randall-Sundrum-like braneworld scenario is constructed in a 5D extension of the Lorentz-violating massive gravity. The gauge hierarchy problem is solved in current model. The li…

Unitary Constraints on Semiclassical Schwarzschild Black Holes in the Presence of Island

Dong-Hui Du, Wen-Cong Gan, Fu-Wen Shu +1

We reconsider dimensional asymptotically flat eternal Schwarzschild black hole, and focus on the situation where the inner boundary of the radiation region is chosen to be…

Casimir Self-Entropy of Nanoparticles with Classical Polarizabilities: Electromagnetic Field Fluctuations

Yang Li, Kimball A. Milton, Prachi Parashar +3

Not only are Casimir interaction entropies not guaranteed to be positive, but also, more strikingly, Casimir self-entropies of bodies can be negative. Here, we attempt to interpret…

Energetics of quantum vacuum friction. II: Dipole fluctuations and field fluctuations

Xin Guo, Kimball A. Milton, Gerard Kennedy +3

As a second paper in series with arXiv:2108.01539, we discuss here quantum vacuum friction on an intrinsically dissipative particle. The friction arises not only from the field flu…

Improved proof-by-contraction method and relative homologous entropy inequalities

Nan Li, Chuan-Shi Dong, Dong-Hui Du +1

The celebrated holographic entanglement entropy triggered investigations on the connections between quantum information theory and quantum gravity. An important achievement is that…

Island and Page curve for one-sided asymptotically flat black hole

Wen-Cong Gan, Dong-Hui Du, Fu-Wen Shu

Great breakthrough in solving black hole information paradox took place when semiclassical island rule for entanglement entropy of Hawking radiation was proposed in recent years. U…
