We construct a bulk spacetime from a boundary conformal field theory, O(N) free scalar model, at finite temperature using a smearing technique, called a conformal flow. The bulk metric is constructed from the thermal two-point function of the smeared boundary elementary field in such a way that it can be interpreted as an information metric associated with the boundary thermofield double state.

HIGHLIGHTED ARTICLES Featured in Physics Femtosecond Reduction of Atomic Scattering Factors Triggered by Intense X-Ray Pulse Phys. Rev. Lett. 131, 163201 (2023) – Published 17 October 2023 Synopsis: Intense X Rays Can Free Bound Electrons Measurements indicate that intense x-ray pulses can change the electronic structure of a material on femtosecond timescales, a finding that could improve imaging of light–matter interactions.

The doubly charmed tetraquark Tcc+ recently discovered by the LHCb Collaboration is studied on the basis of (2+1)-flavor lattice QCD simulations of the D*D system with nearly physical pion mass mπ=146  MeV.
