Ergodicity breaking transition beyond qubits
Tanay Pathak, Abhik Kumar Saha
The local Hilbert space dimension is a fundamental parameter in quantum many-body systems, but its role in controlling the ergodicity-breaking transition remains less explored. We…
Turbulence enhancement of a fan array wind generator using geometric texturing and optimization-based control
Gengshou Cao, Tamir Shaqarin, Zhutao Jiang +5
Fan array wind generators (FAWG) are designed to generate a rich set of turbulent flows reminiscent of those found in natural environments. In this study, we experimentally investi…
Jet mixing enhancement with Bayesian optimization, deep learning, and persistent data topology
Yiqing Li, Bernd R. Noack, Tianyu Wang +4
We optimize the jet mixing using large eddy simulations (LES) at a Reynolds number of . Key methodological enablers consist of Bayesian optimization, a surrogate model enhanc…
A fast converging particle swarm optimization through targeted, position-mutated, elitism (PSO-TPME)
Tamir Shaqarin, Bernd R. Noack
We dramatically improve convergence speed and global exploration capabilities of particle swarm optimization (PSO) through a targeted position-mutated elitism (PSO-TPME). The three…
