Quantum superposition and general and special merge: Remarks on matrix multiplication, tensorization and language evolution [PDF]

Introduction Syntax has long been believed to be the heartbeat of Homo Sapiens. Some (Berwick and Chomsky, 2015) even claim that syntax, and in particular Merge, is the prerequisite of becoming human, differentiating us from the upright man, Homo Erectus,

The shifted harmonic approximation and asymptotic SU(2) and SU(1,1) Clebsch--Gordan coefficients

, 2010
Clebsch-Gordan coefficients of SU(2) and SU(1,1) are defined as eigenfunctions of a linear operator acting on the tensor product of the Hilbert spaces for two irreps of these groups.

Tensor Products of Hilbert Spaces

, 2023
Given a finite or countably infinite family of Hilbert spaces \((H_j)_{j\in N} \), we study the Hilbert space tensor product \(\bigotimes_{j\in N} H_j\). In the general case, these tensor products were introduced by John von Neumann. We are especially interested in the case where each Hilbert space \(H_j\) is given as a reproducing kernel Hilbert space,

Multi‐Material Droplet‐Based Hydrogel Threads for Extrusion 3D Printing

Small Methods, EarlyView.
This study introduces a novel approach to produce multi‐material threads for 3D printing by precisely arranging hydrogel droplets separated by lipid bilayers. By merging the precision of inkjet printing with the scalability of extrusion printing, this method prevents cross‐contamination, maintains material control, and enables intricate designs ...

How the Hilbert space of two-sided black holes factorises

Journal of High Energy Physics
In AdS/CFT, two-sided black holes are described by states in the tensor product of two Hilbert spaces associated with the two asymptotic boundaries of the spacetime. Understanding how such a tensor product arises from the bulk perspective is an important

An algebra structure for reproducing kernel Hilbert spaces [PDF]

Banach Journal of Mathematical Analysis
Reproducing kernel Hilbert spaces (RKHSs) are Hilbert spaces of functions where pointwise evaluation is continuous. There are known examples of RKHSs that are Banach algebras under pointwise multiplication.

Fault diagnosis method of a cascaded H‐bridge inverter based on a multisource adaptive fusion CNN‐transformer

IET Power Electronics, EarlyView.
The multisource adaptive fusion CNN‐transformer method proposed in this study can provide theoretical and technical support for fault diagnosis of high‐voltage MCHBI. It has a promising potential for engineering applications. Abstract In high‐voltage applications, the number of cascaded H‐bridge inverter units is large, the failure probability ...

Functional Sieve Bootstrap for the Partial Sum Process With an Application to Change‐Point Detection

Journal of Time Series Analysis, EarlyView.
ABSTRACT This article applies the functional sieve bootstrap (FSB) to estimate the distribution of the partial sum process for time series stemming from a weakly stationary functional process. Consistency of the FSB procedure under weak assumptions on the underlying functional process is established.

Weak ergodicity breaking with isolated integrable sectors

Physical Review Research
We consider spin chain models with local Hamiltonians that display weak ergodicity breaking. In these models, the majority of the eigenstates are thermal, but there is a distinguished subspace of the Hilbert space in which ergodicity is broken.

A geometric Hamiltonian description of composite quantum systems and quantum entanglement

, 2014
Finite-dimensional Quantum Mechanics can be geometrically formulated as a proper classical-like Hamiltonian theory in a projective Hilbert space. The description of composite quantum systems within the geometric Hamiltonian framework is discussed in this
