Weaving the (AdS) spaces with partial entanglement entropy threads
Jiong Lin, Yizhou Lu, Qiang Wen +1
In the context of the AdS/CFT correspondence, we propose a general scheme for reconstructing bulk geometric quantities in a static pure AdS background using the partial entanglemen…
Cutoff brane vs the Karch-Randall brane: the fluctuating case
Jiong Lin, Yizhou Lu, Qiang Wen
Recently, certain holographic Weyl transformed CFT is proposed to capture the main features of the AdS/BCFT correspondence \cite{Basu:2022crn,Basu:2023wmv}. In this pap…
Geometrizing the Partial Entanglement Entropy: from PEE Threads to Bit Threads
Jiong Lin, Yizhou Lu, Qiang Wen
We give a scheme to geometrize the partial entanglement entropy (PEE) for holographic CFT in the context of AdS/CFT. More explicitly, given a point we geometrize the t…
Ownerless island and partial entanglement entropy in island phases
Debarshi Basu, Jiong Lin, Yizhou Lu +1
In the context of partial entanglement entropy (PEE), we study the entanglement structure of the island phases realized in several 2-dimensional holographic set-ups. The self-encod…
The Markov gap in the presence of islands
Yizhou Lu, Jiong Lin
The Markov gap \cite{Hayden:2021gno}, namely the difference between reflected entropy and mutual information, is explicitly computed in the defect extremal surface model, JT gravit…
Effective reflected entropy and entanglement negativity for general 2D eternal black holes
Jiong Lin, Yizhou Lu
Both reflected entropy and entanglement negativity provide valid measures of entanglement between subsystems of a mixed state. For general 2D eternal black holes coupled with CFT m…
Primordial black holes and scalar induced gravitational waves from Higgs inflation with non-canonical kinetic term
Jiong Lin, Shengqing Gao, Yungui Gong +3
We resolve the potential-restriction problem in K/G inflation by introducing nonminimal coupling. In this context, Higgs field successfully drives inflation satisfying CMB observat…
Double-peaked inflation model: Scalar induced gravitational waves and primordial-black-hole suppression from primordial non-Gaussianity
Fengge Zhang, Jiong Lin, Yizhou Lu
A significant abundance of primordial black hole (PBH) dark matter can be produced by curvature perturbations with power spectrum $Δ_ζ^2(k_{\mathrm{peak}})\sim \mathcal{O}(10^{-2})…
Islands in Kaluza-Klein black holes
Yizhou Lu, Jiong Lin
The newly proposed island formula for entanglement entropy of Hawking radiation is applied to spherically symmetric 4-dimensional eternal Kaluza-Klein (KK) black hole. The "charge"…
Primordial Non-Gaussianity from G-inflation
Fengge Zhang, Yungui Gong, Jiong Lin +2
Enormous information about interactions is contained in the non-Gaussianities of the primordial curvature perturbations, which are essential to break the degeneracy of inflationary…
Spatially covariant gravity with a dynamic lapse function
Jiong Lin, Yungui Gong, Yizhou Lu +1
In the framework of spatially covariant gravity, it is natural to extend a gravitational theory by putting the lapse function and the spatial metric on an equal footin…
On the waveform of the scalar induced gravitational waves
Fengge Zhang, Arshad Ali, Yungui Gong +2
The scalar induced gravitational waves (SIGWs) is a useful tool to probe the physics in the early universe. To study inflationary models with this tool, we need to know how the wav…
Gauge transformation of scalar induced gravitational waves
Yizhou Lu, Arshad Ali, Yungui Gong +2
The gauge dependence of the scalar induced gravitational waves (SIGWs) generated at the second order imposes a challenge to the discussion of the secondary gravitational waves gene…
Primordial black holes and secondary gravitational waves from k/G inflation
Jiong Lin, Qing Gao, Yungui Gong +3
The possibility that in the mass range around most of dark matter constitutes of primordial black holes (PBHs) is a very interesting topic. To produce PBHs with…
Helical phase inflation and its observational constraints
Mudassar Sabir, Waqas Ahmed, Yungui Gong +2
We consider a class of helical phase inflation models from the supergravity where the phase component of a complex field acts as an inflaton. This class of models…
The reconstruction of tachyon inflationary potentials
Qin Fei, Yungui Gong, Jiong Lin +1
We derive a lower bound on the field excursion for the tachyon inflation, which is determined by the amplitude of the scalar perturbation and the number of -folds before the end…
