Relational bulk reconstruction from modular flow

Journal of High Energy Physics
The entanglement wedge reconstruction paradigm in AdS/CFT states that for a bulk qudit within the entanglement wedge of a boundary subregion A ¯ $$ \overline{A} $$ , operators acting on the bulk qudit can be reconstructed as CFT operators on A ...

On the explicit Hermitian solutions of the continuous‐time algebraic Riccati matrix equation for controllable systems

IET Control Theory & Applications
This paper proposes explicit solutions for the algebraic Riccati matrix equation. For single‐input systems in controllable canonical form, the explicit Hermitian solutions of the non‐homogeneous Riccati equation are obtained using the entries of the ...

Asymptotic symmetries, holography and topological hair

Journal of High Energy Physics, 2018
Asymptotic symmetries of AdS4 quantum gravity and gauge theory are derived by coupling the holographically dual CFT3 to Chern-Simons gauge theory and 3D gravity in a “probe” (large-level) limit.

Nonuniform Sampling in L^p-Subspaces Associated with the Multi-Dimensional Special Affine Fourier Transform

Axioms
In this paper, the sampling and reconstruction problems in function subspaces of Lp(Rn) associated with the multi-dimensional special affine Fourier transform (SAFT) are discussed. First, we give the definition of the multi-dimensional SAFT and study its

Characterizations of Pseudo-Symmetric Space–Times in Gray’s Subspaces and f(R)-Gravity Vacuum Solutions

Mathematics
This paper investigates pseudo-symmetric space–times within two interrelated frameworks: vacuum f(R)-gravity and Gray’s seven canonical decomposition subspaces. First, it is established that any conformally flat pseudo-symmetric space–time satisfying the

Searching for Optimal EMG Latent Subspace With Discriminant DoF-Wise Distributions for Subject-Generic Model

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Recognizing hand gestures from surface electromyography (sEMG) signals is crucial for neural interfaces and human–machine interaction. However, developing subject-generic models remains challenging due to substantial inter-subject variability ...

A Low-Rank Tucker Decomposition-Based Channel Estimator for IRS-Assisted mmWave OFDM Systems

IEEE Open Journal of the Communications Society
Intelligent reflecting surface (IRS)-assisted millimeter-wave (mmWave) systems have emerged as a promising solution to enhance coverage and spectral efficiency, while wideband transmission and frequency-selective fading lead to high-dimensional channel ...
