On-shell action of -deformed Holographic CFTs
Jia Tian
In this work, we study the holographic dual of the deformation following the mixed boundary condition proposal. We point out that a boundary term should be…
Negative Rnyi entropy and Brane intersection
Jia Tian, Xiaoge Xu
In this work, we revisit the calculation of Rnyi entropy in AdS/(B)CFT. We find that gravity solutions brane intersection will lead to negative R$\acute{\…

James Halverson, Benjamin Sung, Jiahua Tian
We study electric-magnetic duality in compactifications of M-theory on twisted connected sum (TCS) manifolds via duality with F-theory. Specifically, we study the physics of…

Jiahua Tian, Yi-Nan Wang
We study the orbifold singularities where is a finite subgroup of . M-theory on this orbifold singularity gives rise to a 5d SCFT, which is investigat…
Gauging Discrete Symmetries of -theories in Five Dimensions
Bobby Acharya, Neil Lambert, Marwan Najjar +2
We study the gauging of a discrete symmetry in the five-dimensional superconformal theories. We argue that this leads to an infinite sequence of five-dimension…
