PREM test

M. Keck Computational Materials Theory Center (CMTC) at California State University Northridge (CSUN), a Hispanic-serving institution, by forming a formal and long-term collaborative relationship with the Princeton Center for Complex Materials (PCCM). The goals of the PREM program are to: (1) foster multidisciplinary and innovative research in computational materials science; (2) educate and train students in cutting-edge computational materials science; (3) stimulate and develop strong university-industry-national laboratory partnerships; and (4) increase recruitment, retention, and degree attainment of minority students.

Bias dependence of the spin-current density for the ferromagnetic (FM) and antiferromagnetic (AF) orientations in magnetic tunnel junctions.

The research activities focus in developing physical models and robust simulation techniques to study: 1) mechanical properties of metallic systems; 2) charge and spin transport in various low-dimensional electron systems; and 3) spin transport in magnetic tunneling junctions. Key features of the modeling efforts include studies of the effects: of chemistry on mechanical properties in metals and intermetallics which are potential candidates for structural applications at elevated temperatures; of spin-orbit coupling and disorder on the charge and spin transport properties of two-dimensional strongly correlated electron systems pertinent to spintronic devices, and; of disorder and quantum-well states on the spin torque in single and double magnetic tunnel barriers relevant to spintronic applications. The common theme of these developments involves linking multiple scales (spatial and temporal) and physics that have been traditionally studied in separated disciplines.

The PREM program promotes accessibility of frontier research/education experience in multidisciplinary computational materials science to students from underrepresented groups. We have been developing a sequence of courses for seniors and graduate students that cover materials simulation methods and underlying physics ranging from quantum many-body techniques, ab initio electronic structure, molecular dynamics, kinetic Monte Carlo simulations, and to continuum finite element materials modeling. Through their involvement in cutting-edge research activities, students are exposed to many materials-related physics and computational techniques, and gain skills in scientific programming on parallel computers, numerical analysis and graphic visualizations.

Prof. R. Car from Princeton University with PREM students at the W. M. Keck CMTC

Undergraduates are participating in the REU summer program hosted by PCCM, and are supervised by the Princeton faculty members and/or their Ph. D students to carry out joint research projects. The CMTC has started a Distinguished Lecture Series in which faculty members from Princeton and from other Universities/National Laboratories give public lectures on their cutting-edge research in materials science and engineering. The lecture series, disseminated via web-broadcasting and video streaming, has provided rare opportunities to the faculty and students at CSUN to learn the frontiers of materials research and share the excitement of modern materials research. The establishment of the PREM has significantly advanced the quality of research and education at CSUN to achieve national competitiveness and to promote accessibility of underrepresented students to frontier materials research. The PREM has allowed the access and harness of the intellectual power existing in the two participating institutions. The synergistic collaborations will allow the development of a number of powerful and unique computational approaches/codes that can address the grand challenge problems in materials science and engineering. The research projects have direct applications to nanotechnology. The computational efforts may guide the development of novel materials and devices for aerospace engineering, spintronics and nano-applications. The PREM has allowed us: 1) to expand and strengthen the existing curriculum in materials science at CSUN ; 2) to incorporate an outreach education program for high school students and teachers in materials research; 3) to develop novel techniques for multiscale and multiphysics modeling to study more complex physical phenomena; and 4) to elevate and advance our research and education scopes to a new height. The CMTC is currently planning to host a High School Teacher Materials Camp to make high school teachers aware of the role that computational materials science plays in our daily life and in the development of novel materials. Participants will be provided with instructional materials, which can be disseminated in their classrooms. The CMTC will organize summer workshops to provide participants with hands-on experience in computational materials research, with the emphasis placed on underrepresented undergraduate and graduate students. The CMTC will also establish a consortium of industry/national laboratories partners to sponsor students.
