Physicists ‘Condense’ Diversity, Outreach, Blue Jeans’ Dye in NSF Research
September 25, 2018
Like consumers investing in a pair of body-shaping jeans, the National Science Foundation (NSF) invests in basic research and people to mold the future. So, the government agency awarded more than $500,000 to the University of California San Diego and the University of Texas at San Antonio (UTSA) to study, for the first time, the exploration of the electronic and magnetic behavior of one-dimensional (1D) metallic chains. In this case, these are ultra-short chains of atoms that can be fabricated using organic molecules called metallo-phthalocyanine (MPc)—flat molecules with a metal atom at the center commonly used in dyes present in the color of blue denim. The findings could lead to the development of new, smaller and faster electronic devices that can be used in computer memory, as well as to promising careers for future scientists.

Our Proposal: "Collaborative Research: Quantum Spin Chains. Extent and Persistence of Magnetic Interactions as a Function of Length and Spin" has been Funded by NSF
May 7, 2018
This research is in the field of organic materials and low-dimensional systems. It consists of the fabrication of ultra-short chains (7 to 200 atoms long) with variable composition (and spin) to test quantum magnetic models, study the interplay of quantum and thermal fluctuations, and explore the emergence of new magnetic phases. This study will provide a broader and deeper understanding of the magnetic behavior of low-dimensional systems and may have a direct impact on the development of a new generation of spintronic devices.
Besides the scientific aims, this research has an active educational component. The project will involve two graduate students who will perform research for their Ph.D. thesis topic and two physics undergraduate students per semester. These students will receive training at first synchrotron and neutron facilities and will be exposed to state of the art advanced experimental techniques.
