Job Location: Oak Ridge, TN

We are seeking a Postdoctoral Research Associate to support projects in numerical studies of models of correlated electron systems. In this role, you will work alongside our team of dedicated and interdisciplinary researchers and have the opportunity to share your results with the scientific community. Your priorities will include the development, efficient parallel implementation, and application of high-end computational methods, including determinantal and dynamic cluster quantum Monte Carlo approximations and density matrix renormalization group techniques. Ultimately, we want to use these methods to understand the fundamental properties of unconventional superconductors, quantum spin liquids, and related materials.As a postdoc, you will be mentored by and collaborate with leading condensed matter theorists, applied mathematicians, and computer scientists at both Oak Ridge National Laboratory (ORNL) and the University of Tennessee, Knoxville (UTK) in the development and application of state-of-the-art computational quantum many-body techniques and their implementation, specifically targeted for ORNL's current and future leadership computing facilities. This position resides within the Nanomaterials Theory Institute (NTI) in the Center for Nanophase Materials Sciences (CNMS), Physical Sciences directorate (PSD) in close collaboration with the Computational Chemical and Materials Sciences (CCMS) group in the Computational Sciences and Engineering Division (CSED). This joint effort provides scientific software development, application, and expertise for chemical and materials sciences and more broadly for nanoscience as part of the CNMS user program. The CNMS ( is a user facility supported by the Office of Science, U.S. Department of Energy (DOE).

Major Duties/Responsibilities:
  • Develop high-end numerical quantum many-body methods
  • Develop scalable and efficient implementations of these algorithms for state of the art high-performance computing architectures
  • Use these methods and codes to study model Hamiltonians of unconventional superconductors and spin liquid materials.
  • Present and report research results and publish scientific results in peer-reviewed journals in a timely manner
  • Ensure compliance with environment, safety, health and quality program requirements
  • Maintain strong dedication to the implementation and perpetuation of values and ethics

    Qualifications Required:
  • A Ph.D. degree in computational physics or a related field completed within the last five years
  • A background in computational condensed matter physics
  • Experience in the application of numerical quantum many body methods to study model HamiltoniansPREFFERED QUALIFICATIONS:
  • A strong record of productive and creative research proven by publications in peer-reviewed journals and presentations at major conferences
  • Excellent interpersonal skills, oral and written communication skills, and the ability to communicate in English to an international scientific audience
  • Motivated, safety conscious, and organized
  • Ability to work with a measure of autonomy, but also in a dynamic, team environment to interact effectively with your colleagues, develop new collaborations to improve scientific understanding, and accept flexibility in research assignments
  • Basic understanding of parallel application development techniques (parallel programming models, algorithms, and software)
  • Familiarity with common scientific programming languages such as C/C++ or Fortran
  • Experience in parallel programming with one or more common parallel programming models, like MPI, PGAS, OpenMP, CUDA, OpenCL, and OpenACC.
  • Experience in heterogeneous programming (ie, GPU programming) and/or developing, debugging, and profiling massively parallel codes
  • Experience developing large computer codes and/or developing in a team environmentOTHER INFORMATION:Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding. Please provide a list of publications when applying for this position. Three letters of reference are required and can be uploaded to your profile or emailed directly to THIS EMAIL . Please include the title of the position in the subject line.
