Authors: Xiao Luo, Yoshinobu Kuramashi
Abstract summary: We investigate the entanglement and R'enyi entropies for the sigma+1-dimensional O(3) nonlinear model. The central charge is determined from the scaling properties of both entropies.

Abstract: We investigate the entanglement and R\'enyi entropies for the (1+1)-dimensional O(3) nonlinear sigma model using the tensor renormalization group method. The central charge is determined from the asymptotic scaling properties of both entropies. We also examine the consistency between the entanglement entropy and the $n$th-order R\'enyi entropy with $n\rightarrow 1$.

Recent studies show that a reproducing kernel Hilbert space (RKHS) is not a suitable space to model functions by neural networks. In this paper, we study a suitable function space for over- parameterized two-layer neural networks with bounded norms.

"Statistical-computational gaps" occur in many statistical inference tasks. We consider a model for random order-3 decomposition where one component is slightly larger in norm than the rest. We show that tensor entries can accurately estimate the largest component when $ll n3/2$ but fail to do so when $rgg n3/2$.

Deep inelastic scattering (DIS) samples a part of the wave function of a hadron in the vicinity of the light cone. We show that the resulting entanglement entropy depends on time logarithmically, $mathcal S(t)=1/3 ln(t/tau)$ with $tau = 1/m$ for $1/m le tle (mx)-1$, where $m$ is the proton mass and $x$ is Bjorken $x$.

We show that for two-dimensional conformal theories defined in a torus, a choice of moduli space allows the typical entropy operator of the TFD to provide the entanglement entropy. We also propose a model for the evolution of the entanglement entropy and show that it grows linearly with time.
