Molecular Properties from Quantum Krylov Subspace Diagonalization. [PDF]
Quantum Krylov subspace diagonalization is a prominent candidate for early fault-tolerant quantum simulation of many-body and molecular systems, but so far, the focus has been mainly on computing ground-state energies.

Quantum Spectral Clustering Framework via Compact Circuit Structures
Can a quantum computer cluster data without ever reading the full kernel? This work shows that compact, parameterized circuits estimate the Laplacian quadratic forms directly and perform clustering, without explicitly constructing the full quantum fidelity‐kernel matrix.

Abstract High‐resolution crustal‐scale seismic imaging from long‐offset ocean‐bottom seismometer (OBS) data using full‐waveform inversion (FWI) remains challenging because the large number of propagated wavelengths and waveform complexity make the inversion highly sensitive to time‐shift errors (cycle skipping). To mitigate this nonlinearity, we assess

Krylov Implicit Integration Factor Methods for Semilinear Fourth-Order Equations
Implicit integration factor (IIF) methods were developed for solving time-dependent stiff partial differential equations (PDEs) in literature. In [Jiang and Zhang, Journal of Computational Physics, 253 (2013) 368–388], IIF methods are designed to ...

ABSTRACT Modern high‐voltage power systems increasingly rely on power semiconductor devices for energy conversion, control and transmission. Device design, optimisation and failure analysis require knowledge of the internal distributions of electric field, carrier density and temperature, which are difficult to obtain directly from terminal electrical ...

Basic principles and aims of model order reduction in compliant mechanisms [PDF]
Model order reduction appears to be beneficial for the synthesis and simulation of compliant mechanisms due to computational costs. Model order reduction is an established method in many technical fields for the approximation of large-scale linear time ...
