Rapid Funding opportunity from the Center for Nonlinear Studies
CNLS is searching for a new director
The Theoretical Division (T) and the National Security Education Center
(NSEC) at the Los Alamos Nationall Laboratory are searching for a Director
for the Center for Nonlinear Studies (CNLS). The Center Director provides
scientific leadership and line management of the CNLS while fostering
collaborations with scientists throughout the Laboratory. The CNLS Center
Director is expected to develop and lead a program to target and create
cooperative long-term research programs consistent with the Laboratory’s
strategic research objectives, to develop a strong working relationship with
the CNLS External Advisory Committee, and to maintain effective working
relationships throughout all levels of the Laboratory, government entities,
academia and industry. For further information, please look at the center
overview or contact Melanie Vigil (firstname.lastname@example.org).

- CNLS postdoctoral fellow, Prajvala Kurtakoti, has been featured in the journal Scientia for her research as a polar oceanographer. Prajvala Kurtakoti studies climate models, ocean circulation patterns, and the dynamical effects resulting from the coupling between the oceans and the atmosphere and heat transport between them.
- CNLS Postdoctoral fellow Marco Cerezo and coauthor have demonstrated Variational Quantum Algorithms (VQAs) may be a path to quantum advantage on Noisy Intermediate-Scale Quantum (NISQ) computers. The article can be found in “Noise-induced barren plateaus in variational quantum algorithms by S. Wang, E. Fontana, M. Cerzo, K. Sharma, A. Sone, L. Cincio & P. J. Coles, in Nature Communications. DOI: .1038/s41467-021-27045-6.
- CNLS postdocs Derek DeSantis (CCS-2/CNLS) and Adam Rupe (EES-16/CNLS) are researchers who are part of a team who won a RD 100 Award. Their winning project, SmartTensors AI Platform, is software that uses unsupervised machine learning to sift through massive datasets and identify hidden trends, mechanisms, signatures, and features buried in large high-dimensional data tensors (multi-dimensional arrays). The SmartTensors AI Platform project also won the Bronze Special Recognition Award for Market Disruptor – Services, which highlights any service from any category as one that forever changed the R&D industry or a particular vertical within the industry.
- CNLS Executive Committee member Sara Del Valle led the Los Alamos team who received the Gold Special Recognition Award in the Battling COVID-19 category for their project EpiCast Simulates Epidemics in Extreme Scales. This award highlights any innovation that was employed to battle the worldwide COVID-19 pandemic. CNLS postdocs Morgan Gorris (A-1/CNLS) and Manhong Z. Smith (A-1/CNLS) are part of the team that won.
- CNLS Postdoctoral fellow Julia Cen (T-4/CNLS) won best video poster presentation at the International Quantum Fest 2021 conference. Quantum Fest is a periodic festival on Quantum Phenomena, Quantum Control and Geometry of Quantum States, organized by the Center for Research and Advanced Studies (Cinvestav) and Unidad Profesional Interdisciplinaria en Ingeniería y Tecnologías Avanzadas del I.P.N. (UPIITA-IPN) in México City, Mexico. The jury of the video-posters exhibition consists of Lecturers and the Plenary Speakers of the conference. The originality and scientific rigor of results as well as the exposition and the aesthetic of the cartel are taken into account. Julia Cen won the first place in the poster presentation. Presentation title: Joint Parity-Time (PT) and Anti-Parity-Time (APT) Symmetric Qubits.
- CNLS Postdoctoral fellow Zachary Fox employed a recently developed tool
named aging Wiener-Khinchin theorem to derive the power spectral density of fractional Brownian motion coexisting with a scale-free continuous time random walk, the two most typical anomalous diffusion processes. Using this analysis, they characterized the motion of voltage-gated sodium channels on the surface of hippocampal neurons. Their results show aging where the power spectral density can either increase or decrease with observation time depending on the specific parameters of both underlying processes. The article, “Aging power spectrum of membrane protein transport and other subordinated random walks”, by Zachary Fox, Eli Barkai and Diego Krapf, Nature Communications (2021) 12:6161, can be found here (https://www.nature.com/articles/s41467-021-26465-8.pdf).
- Wenting Li, a post-doc in CNLS and Applied Mathematics and Plasma Physics (T-5), recently received a “best paper” award for Machine Learning (ML) Innovation at the Climate Change AI workshop at the 2021 International Conference on Machine Learning (ICML). She and her mentor Deepjyoti Deka design graph neural networks for identifying the location of power grid faults that may trigger blackouts or wildfires using physics. The highlight of this research is that it can work in realistic regimes where power networks are sparsely observed and data is partially labeled.
