I first explain that the classical scale invariance is a necessary condition for the calculability of the vacuum energy. Then, I discuss how sufficient the scale invariance is for solving the cosmological constant problem as well as the gauge hierarchy problem.

We prove that there is an open string in the spectrum of holographic Fermion coupled with a scalar. The string ends at two fermions and its tension vanishes in the limit of zero scalar condensation. We call it “entanglement string”. The model shows a Mott transition so that together with divergently large entanglement entropy, our model is qualified to describe the Resonating Valence Bond

The gauge symmetry breaking in string models with Dbranes is discussed. Starting from a simple argument that the parallel separation of Dbranes exhibits spontaneous gauge symmetry breaking, the mechanism of rank reduction of gauge group, which is necessary for realistic electroweak symmetry breaking, is discussed. The mechanism for a fixed stable scale of gauge symmetry breaking, which is necess

Recently, there has been a fundamental and significant development in the GreenSchwarz (GS) formulation of superstring theory. In this formulation, the kappasymmetry plays a central role to ensure the consistency of the theory. In 2016, Tseytlin and Wulff showed that the kappasymmetry constraints of the GS superstring defined on an arbitrary background lead to a ``generalized'' supergravity, wh

First we explain our recent conjecture that a gravity dual of a quantity called entanglement of purification is given by the minimal area of entanglement wedge cross section in AdS. This provides a simple generalization of holographic entanglement entropy to mixed states. Then we argue that in AdS3/CFT2 setups, the holographic entanglement of purification agrees with the entanglement entropy in a

I argue that the AntideSitter (AdS) geometry in $d+1$ dimensions naturally emerges from an arbitrary conformal field theory in $d$ dimensions using the free flow equation. I first show that an induced metric defined from the flowed field generally corresponds to the quantum information metric, called the Bures or Helstrom metric, if the flowed field is normalized appropriately. I next verify tha

We discuss moduli stabilization of the Ftheory compactified
on elliptically fibered CalabiYau fourfolds.
We turn on appropriate Gfluxes to stabilize all the complex structure moduli fields,
corresponding to the open and closed string moduli in the type IIB limit.
It is found that they can be stabilized at the Minkowski or de Sitter minimum.
We also discuss the swampland conjecture in the g
