CRCNS - Microimaging/modeling of retinal responses measured with laser magnetometers

Igor Savukov, LANL Staff Scientist, NMC Affiliate
 
The goal of this research is to conduct nuclear-spin optical rotation (NSOR) experiments at Texas A&M university in collaboration with the Dr. Christian Hilty at his dynamic nuclear polarization (DNP) facility. NSOR can be of interest to applications related to National Security and it is imperative that basic science be investigated in order to evaluate the potential for National Security applications.
 

Collaborative Research: DNP-Enhanced Nuclear Spin Optical Rotation Spectroscopy

Igor Savukov, LANL Staff Scientist, NMC Affiliate
 
The project goal is to conduct nuclear-spin optical rotation (NSOR) experiments at Texas A&M university in collaboration with Prof. Hilty. Previously, with Early Career LDRD funding this collaboration was established and some preliminary experiments were done at Texas A&M. The LDRD project has ended, but there are opportunities for continuing the research in this direction. Prof. Hilty has unique dynamic nuclear polarization (DNP) facility which is essential for the proposed project, and NSF funding mechanism is ideal for such collaboration. Dr. Savukov involvement will be the guidance of the experiments and analysis, remotely and at the site at Texas. NSOR can be of interest to applications related to National Security; however, at this initial stage of development basic science needs to be investigated in order to evaluate the potential for National Security applications. This project is sponsored by the NSF, and is a collaboration with Texas A&M.
 

Multidisciplinary investigation of the mammalian inner ear as  radio-frequency antenna, demodulator, and transducer

William Bruno, NMC Scientist
 
The NMC team will be modeling the electrical properties of the inner ear, in collaboration with University of Utah, and UNM, where radio-frequency experiments will be carried out on model antennas. Experiments on whether rodents respond to certain types of pulsed radio signals will be conducted by the Lovelace Biomedical Research Institute in Albuquerque.Other institutions participating in the program include Caltech, UCSD, University of Michigan, and Georgia Tech Research Institute. This research is funded by DARPA.

Bob Robey, LANL Staff Scientist, NMC Affiliate
Jeff Bowles
 
In this project the Higrad suite of codes is being ported to run on next generation architectures including the Intel Xeon Phi, GPUs such as the Nvidia architecture and larger numbers of multi-core processors. The scope of the work includes the development of test suites, code quality improvements, documentation, robustness, optimizations and finally the scaling of the application to run on tens to hundreds of thousands of processes.
 

Method for Testing Hydrophobic Materials for their Ability to Prevent Biofilm Formation and Why it is Important

Steven Buelow, NMC Chief Executive Officer and Scientist 

The objective of this project is to determine the relative susceptibility to biofilm formation on the surfaces of materials of various compositions, in samples provided by the National Aeronautics and Space Administration (NASA), exposed to actively growing algae in open cultivation ponds. This project is sponsored by NASA.

Computational and Theoretical Studies of Ultracold Plasmas: Exploring the Physics of Strongly Coupled Plasmas with Large Scale Simulations

Steven Buelow, NMC Chief Executive Officer and Scientist
Chris Fichtl
Matt Calef
Paul Grabowski
 
This research aims to greatly expand our knowledge of strongly coupled plasmas in three key areas: the approach to equilibrium, the edge of the hydrodynamic limit, and particle and energy transport. Most of our efforts will focus on how these advances can exploit the achievement of ultracold, quasi-neutral plasmas in experiments. In particular, we will examine concepts that could lead to the development of more strongly coupled plasmas in experiments, which are currently limited to the moderately coupled plasma regime.

Turbulence and Particle Energization in Low-Beta Plasmas

Hui Li, LANL Staff Scientist
Xiangrong Fu, NMC Research Scientist
 

As part of the DoE/OFES project at LANL, this project performs advanced numerical simulations to study the current sheets and particle energization in turbulent plasmas. This has applications for  space, solar and astrophysical plasmas. Dr. Xiangrong Fu from the NMC has developed hybrid and  kinetic simulation techniques that can contribute to this project. He shall utilize these codes to  study the effects of turbulence on particle energization and identify possible applications of these  processes in systems such as solar wind, solar corona and accretion disk corona. This is an important part of our DoE/OFES project.

Probing Non-standard Time-reversal Violating Higgs Interactions: From Electric Dipole Moments to Colliders

Vincenzo Cirigliano, LANL Scientist, NMC Affiliate
 
This project involves research in theoretical physics, with both analytic and computational work. The aim of the project is to better understand the properties of the newly discovered Higgs boson, through a combination of constraints that range from low-energy experiments (for example the search for the neutron electric dipole moment) all the way to high-energy particle collider experiments.
