CLUSTER: Derivative-free optimization of smooth functions with parameter-change costs
Serena Landers, Sahil Pontula, Shiekh Zia Uddin +3
We introduce the CLUSTER algorithm (\textbf{c}oordinate-\textbf{l}evel \textbf{u}pdate \textbf{s}trategy for \textbf{t}rust-region step \textbf{e}valuation \textbf{r}efinement) for…
Long-range entanglement and quantum correlations in a multi-frequency comb system
Sahil Pontula, Debasmita Banerjee, Marin Soljacic +1
Frequency combs are multimode photonic systems that underlie countless precision sensing and metrology applications. Since their invention over two decades ago, numerous efforts ha…
Probing intensity noise in ultrafast pulses using the dispersive Fourier transform augmented by quantum sensitivity analysis
Shiekh Zia Uddin, Sahil Pontula, Jiaxin Liu +4
To reach the next frontier in multimode nonlinear optics, it is crucial to better understand the classical and quantum phenomena of systems with many interacting degrees of freedom…
Flow-based sampling for multimodal and extended-mode distributions in lattice field theory
Daniel C. Hackett, Chung-Chun Hsieh, Sahil Pontula +7
Recent results have demonstrated that samplers constructed with flow-based generative models are a promising new approach for configuration generation in lattice field theory. In t…
