The precise determination of the Newtonian gravitational constant, G, remains one of the most challenging problems in experimental physics, with existing measurements showing significant discrepancies despite continual improvements in accuracy. This work aims to develop a high-precision torsion balance apparatus designed to measure G with a target relative uncertainty of approximately 2 ppm....
Applying a rule-based holographic method, we investigate the reconstruction of dual gravity theories from the quantum field theory (QFT) data, specifically, entanglement entropy. We first derive a three-dimensional black hole geometry from the entanglement entropy of a two-dimensional thermal system. Using the reconstructed solution, we extract various thermodynamic quantities with small...
In this talk, we consider the Ellis-Bronnikov wormhole to see the gravitational waves generation due to the particle motion around the wormhole. The orbiting-around and the falling-into cases are also discussed. The ringdown phase of the wormhole is also studied from the perturbation equation driven by the particle motion.
We propose an inflationary mechanism for primordial magnetic-field generation based on the reduced open-system dynamics of photon modes in de~Sitter space. The observable photon sector inside a causal patch is treated as a Gaussian subsystem, while the de~Sitter horizon acts as an effective environment at the Gibbons--Hawking temperature. Since the reduced state relaxes only with a finite...
We formulate a continuous operator-algebraic recovery path for black-hole information based on modular (L^p)-interpolation. The starting point is the canonical shift of algebraic teleportation, which relocates hidden information from one relative commutant to another. In local quantum field theory, this finite-step picture cannot be implemented through ordinary tensor-factor decompositions...
I review my personal contribution to the dark matter as the Bose liquid and the holographic mean field theory of non-fermi liquid.
Finally I will describe how disorders can introduce the non-locality out of local quantum field theory, which is essential for the recent development of
the strange metal.
We investigate scalarized Einstein-Euler-Heisenberg (EEH) black holes
in the EEH-scalar theory. Firstly, we carry out negative potential-induced scalarization by considering the minimally scalar coupling. Spontaneous scalarization of EEH black hole is also performed by introducing an exponential scalar coupling to Maxwell term and nonlinear electrodynamics (NED) term.
