We consider a bottom-up AdS/QCD model with conformal exponential deformation ekIz2 on Lorentz invariant AdS background, where kI stands for the scale k? that fixes confinement in pion case and k? kinematical energy associated virtual photon. In this we assume dimension operator creates pions at boundary as ?=3, original proposals. Regarding geometric slope related to photon field k?, analyze tw...

We bootstrap the three-point form factor of chiral part stress-tensor supermultiplet in planar $\mathcal{N}=4$ super-Yang-Mills theory, obtaining new results at three, four, and five loops. Our construction employs known conditions on first, second, final entries symbol, combined with multiple-final-entry conditions, ``extended-Steinmann-like'' near-collinear data from recently-developed operat...

We theoretically study correlations present deep in the spectrum of many-body-localized systems. An exact analytical expression for spectral form factor Poisson spectra can be obtained and is shown to agree well with numerical results on two models exhibiting many-body-localization: a disordered quantum spin chain phenomenological $l$-bit model based existence local integrals motion. also ident...

One manifestation of quantum chaos is a random-matrix-like fine-grained energy spectrum. Prior to the inverse level spacing time, random matrix theory predicts “ramp” increasing variance in connected part spectral form factor. However, realistic chaotic systems, finite-time dynamics factor much richer, with pure ramp appearing only at sufficiently late time. In this article, we present hydrodyn...
