Postdoctoral Research Associate - Theory and Modeling of Dynamics in Condensed Matter

Date: Nov 25, 2025

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 15637 

 

Overview:

Oak Ridge National Laboratory is the largest US Department of Energy (DOE) science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.

 

We are seeking a Postdoctoral Research Associate who will focus on theoretical studies of nonequilibrium dynamics in many-body systems. This position resides in the Quantum Heterostructures Group in the Foundational & Quantum Materials Science Section, Materials Science and Technology Division, Physical Sciences Directorate at Oak Ridge National Laboratory (ORNL). 

 

As part of our research team, you will closely collaborate with a team that includes condensed matter theorists, experts in neutron/X-ray scattering, and experts in thin film and single crystal material’s growth and characterization. You will perform cutting-edge research on theory and modeling of dynamics in condensed matter.

 

Major Duties/Responsibilities:

  • Development of theoretical framework for driven and open quantum systems.
  • Phenomenological modeling of dynamics/transport behaviors in complex systems, including strongly correlated electron systems.
  • Experience in analyzing data from scattering experiments.
  • Work with others to maintain a high level of scientific productivity.
  • Publish scientific papers in key journals and present at key meetings.
  • Ensure compliance with environment, safety, health, and quality program requirements.
  • Maintain a strong commitment to the implementation and perpetuation of values and ethics.
  • Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service.

 

Basic Qualifications:

  • A PhD in in condensed matter physics, theoretical physics, quantum information, or a closely related field completed within the last five years.
  • Good track record in scattering theory, quantum many-body theory, thermodynamics, statistical mechanics, or non-equilibrium physics.
  • Experience in phenomenological and/or computational methods for quantum/classical dynamics in complex system.

 

Preferred Qualifications:

  • Rich experience with modeling in spin or atomic dynamics will be highly advantageous.
  • Basic knowledge of models of strongly correlated electron systems.
  • Proficiency with scripting or programmatic languages, such as Python, c, and MATLAB.
  • Excellent written and oral communication skills.
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever-changing needs.

 

Special Requirements:

Applicants cannot have received their PhD 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 submit two letters of reference when applying to this position. You may upload these directly to your application or have them sent to recruiting@ornl.gov with the position title and number referenced in the subject line.

Security, Credentialing, and Eligibility Requirements:

  • This position requires the ability to obtain and maintain an HSPD-12 PIV badge.
  • For employment at Oak Ridge National Laboratory (ORNL), a Real ID compliant form of identification will be required.
  • Additionally, ORNL is subject to Department of Energy (DOE) access restrictions. All employees must also be able to obtain and maintain a federal Personal Identity Verification (PIV) card as mandated by Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which requires a favorable post-employment background investigation.
  • To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws.

 

For foreign national candidates:

  • If you have not resided in the U.S. for three consecutive years, you are not eligible for the PIV credential and instead will need to obtain a favorable Local Site Specific Only (LSSO) risk determination to maintain employment.
  • Once you meet the three-year residency requirement, you will be required to obtain a PIV credential to maintain employment.

 

Benefits at ORNL:

We offer competitive pay and benefits programs to attract and retain hardworking people! The laboratory offers many employee benefits, including medical and retirement plans and flexible work hours, to help you and your family live happy and healthy. Employee amenities such as on-site fitness, banking, and cafeteria facilities are also provided for convenience.

 

Other benefits include the following: Prescription Drug Plan, Dental Plan, Vision Plan, 401(k) Retirement Plan, Contributory Pension Plan, Life Insurance, Disability Benefits, Generous Vacation and Holidays, Parental Leave, Legal Insurance with Identity Theft Protection, Employee Assistance Plan, Flexible Spending Accounts, Health Savings Accounts, Wellness Programs, Educational Assistance, and Employee Discounts. Relocation Assistance is available for certain positions.

 

If you have difficulty using the online application system or need an accommodation to apply due to a disability, please email: ORNLRecruiting@ornl.gov.

 

This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired.
