Probing Quantum Spin Systems with Kolmogorov-Arnold Neural Network Quantum States
Neural Quantum States (NQS) are a class of variational wave functions parametrized by neural networks (NNs) to study quantum many-body systems. In this work, we propose SineKAN, the NQS ansatz based on Kolmogorov-Arnold Networks (KANs), to represent quantum mechanical wave functions as nested univariate functions. We show that \sk wavefunction with learnable sinusoidal activation functions can capture the ground state energies, fidelities and various correlation functions of the 1D Transverse-F…

Heute vor 20 Jahren: Am 27. Juni 2005 wurde im #Kernkraftwerk #FitzPatrick (USA) ein Riss im Torus entdeckt, der zu einer möglichen Gefährdung der Containment-Dichtigkeit führte (INES 1). Ein Notfall wurde ausgerufen und das Werk heruntergefahren, um Reparaturen durchzuführen.

Source Identification Problem for a Nonlinear Subdiffusion Equation
The work is devoted to the study of the inverse problem of determining the right-hand side of a nonlinear subdiffusion equation with a Caputo derivative with respect to time. Nonlinearity of the equation means that the right-hand side of the equation depends nonlinearly on the solution of the equation. The inverse problem consists of reconstructing the coefficient of the right-hand side, which depends on both time and spatial variables, under a measurement in an integral form. Similar inverse p…
