T-duality of string charge density/bit threads correspondence in type II supergravity
Houwen Wu, Shuxuan Ying
In this paper, we study Abelian T-duality of the string charge density/bit threads correspondence in ten-dimensional Type II supergravity. T-duality along the common compact circle…
Mixed State Entanglement Entropy in CFT
Xin Jiang, Peng Wang, Houwen Wu +1
How to calculate the entanglement entropy between two subsystems for a mixed state has remained an important problem. In this paper, we provide a straightforward method, namely the…

Xin Jiang, Peng Wang, Houwen Wu +1
We provide a concrete and computable realization of the conjecture, by deriving the Einstein-Rosen bridge from the quantum entanglement in the thermofield double CFT. The…

Xin Jiang, Peng Wang, Houwen Wu +1
The {\it finiteness} of the entanglement entropies between disjoint subsystems enables us to show that, the dynamical equation of the entanglement entropy in CFT is precisely t…

In this paper, our aim is to illustrate that the process of open string scattering corresponds to the evolution of the entanglement wedge, where the scattering distance is identifi…
An alternative to purification in CFT
Xin Jiang, Peng Wang, Houwen Wu +1
In conformal field theories, in contrast to \emph{adding} some auxiliary states into the bipartite mixed state as the usual purifications do, we show a pure entangled stat…

Peng Wang, Houwen Wu, Haitang Yang
In this paper, we establish connections between reflected entropies of multipartite mixed states in CFT and hyperbolic string vertices of closed string field theory (CSFT). W…
Derive Lovelock Gravity from String Theory in Cosmological Background
Peng Wang, Houwen Wu, Haitang Yang +1
It was proved more than three decades ago, that the first order correction of string effective theory could be written as the Gauss-Bonnet term, which is the quadratic term of…
Non-singular string cosmology via corrections
Peng Wang, Houwen Wu, Haitang Yang +1
In string theory, an important challenge is to show if the big-bang singularity could be resolved by the higher derivative corrections. In this work, based on the Hohm-Zwiebac…

Peng Wang, Houwen Wu, Haitang Yang +1
For the bosonic gravi-dilaton system, we provide systematical approaches to construct non-perturbative string cosmological solutions without curvature singularities, which can matc…

Qingyu Gan, Guangzhou Guo, Peng Wang +1
It has been shown that the Strong Cosmic Censorship (SCC) can be violated by a scalar field in a near-extremal Reissner-Nordstrom-de Sitter black hole. In this paper, we investigat…
