Job Description

Are you passionate about your work and dream of utilizing state-of-the-art facilities to explore solutions? Do you want to join a dynamic team that solves significant issues for our nation’s security? We are seeking a postdoctoral researcher to perform research in computational physics: developing and applying first-principles methods like quantum Monte Carlo and Density Functional Theory to study the properties of materials. On any given day, you may be called upon to: + Develop systematically improvable techniques to calculate properties such as high-pressure phase transitions, determination of defect energies and reaction barriers. + Develop a consistent framework for treating relativistic effects in materials + You will have extensive interactions with groups at several other institutions developing electronic structure techniques and collaboration with experimental groups at Sandia regarding the selection of promising avenues of research + You will need to work efficiently as part of collaborative efforts, publish results in scientific journals and present work at conferences.

+ You have PhD in Physics, Chemistry, or Materials Science or a similar discipline + You have experience with research in many-body theory and advanced electronic structure methods such as quantum Monte Carlo (QMC), post Hartree-Fock quantum chemistry methods, Density Functional Theory (DFT), or time-dependent DFT. + You have evidence of good written and verbal communication skills and a proven record of success in independent research as evidenced through technical publications and reports.

+ Ability to obtain and maintain a DOE security clearance. + Demonstrated ability to be self-motivated and to work effectively with others as part of a team. + An interest and ability to perform a variety of first-principles simulations based on for example Diffusion Monte Carlo (DMC), Variation Monte Carlo (VMC), Path Integral Monte Carlo (PIMC), DFT, or TDDFT. + Experience of generation of pseudo-potentials or related fundamental work in computational physics. + Experience with relativistic computational quantum mechanics + Knowledge of thermodynamics and shock physics. + Interest in high-energy density physics theory.

Department Description:

Research within the High Energy Density Physics (HEDP) Theory Department 1641 spans a broad range of topics with a common theme of gaining an improved understanding of physical processes at normal as well as extreme conditions of high densities and/or temperatures, pressures, magnetic fields, and rapidly changing states. Major efforts of the department include developing simulations codes and high-fidelity material models with predictive capabilities together with designing dynamic material and plasma physics experiments for Sandia's Z Machine. Our research has both applied and fundamental dimensions – for example in the areas of electronic structure, shock physics, material science, planetary science and astrophysics. More specifically, work at the department involves fundamental research in materials- and plasma physics: i) using multi-physics codes to design, analyze, and optimize experiments on Sandia’s Z-machine; ii) developing two-fluid and magnetohydrodynamics simulation codes; and iii) developing and applying methods based on quantum mechanics, primarily Density Functional Theory and Quantum Monte Carlo, for developing both an improved understanding and quantitative models for materials properties. The department has active collaborations with research groups at Los Alamos National Laboratory, Lawrence Livermore National Laboratory, Oak Ridge National Laboratory, and Argonne National Laboratory as well as with academic institutions in the US and in Europe, including University of Illinois Urbana Champaign, University of Rochester, Washington State University, Michigan State University, North Carolina State University, Harvard University, University of Rostock in Germany, Princeton University, Cornell University, University of California Davis, University of California Berkeley, and University of Texas at Austin.

Security Clearance:

Position requires a Department of Energy (DOE) Q-level security clearance. Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.

EEO Statement:

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status. : This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
