We havean opening for a Postdoctoral Researcher in the field of first-principles quantum mechanical simulations of correlated materials, with particular emphasis on the development and application of quantum Monte Carlo methods.The candidate will work closely with a multidisciplinary team in support of projects sponsored by DOE-BES and DOE-ASCR. The position is in the Quantum Simulations Group of the Physics Division.

Essential Duties
- Develop and apply theoretical models to study the strong coupling between charge, spin, orbital and lattice degrees of freedom in correlated materials.
- Develop and implement novel extensions to quantum Monte Carlo methods.
- Design and perform accurate simulations using state-of-the-art first-principles approaches, including quantum Monte Carlo methods.
- Publish research results in external peer-reviewed scientific journals and participate in conferences.
- Present formal and informal overview of research progress at weekly meetings.
- Participate in existing Division collaborations and alliances with academia and industry.
- Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally.
- Perform other duties as assigned.

- Recent Ph.D. in physics, chemistry, materials science, or related field.
-Experience inquantum Monte Carlo methods.
- Experience and background in parallel computing and first principles simulations.
- Experience in the application of density functional theory to simulations of materials.
- Ability as an innovative theorist with a broad range of experience in atomistic simulation codes, data acquisition, and data analysis.
- Ability to develop independent research projects through publication of peer-reviewed literature.
- Proficient verbal and written communication skills as reflected in effectivepresentations at seminars, meetings and/or teaching lectures.
- Initiative and interpersonal skills with desire and ability to work in a collaborative, multidisciplinary team environment.
Desired Qualifications
- Experience in one or more of the following application areas: strongly correlated materials, transition metal oxides, materials at high pressure and high temperature.
- Experience performing large-scale ab initio simulations on high-performance computing environments.
- Proficiency in C++, Python, and/or FORTRAN.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance: None required.

However, if your assignment is longer than 179 days cumulatively within a calendar year, you must go through the Personal Identity Verification process. This process includes completing an online background investigation form and receiving approval of the background check. (This process does not apply to foreign nationals.)

Note: This is a twoyear Postdoctoral appointment with the possibility of extension to a maximum of threeyears. Eligible candidates are recent PhDs within five years of the month of the degree award at time of hire date.
