Decoherence in Molecular Nanomagnets @ University of Southern California
Nontechnical Abstract:
Molecular nanomagnets are nanometer scale magnets that produce a large magnetic field. Because of the quantum nature in their magnetism and capability to tune their magnetic properties, molecular nanomagnets are promising materials for future applications of nano-scale magnetic storage and quantum information processing devices. This project entails a research plan that integrates the investigation and control of quantum memory time, known as quantum decoherence time, in molecular nanomagnets with innovative inter-disciplinary educational and outreach activities centered at the University of Southern California (USC). The research activities focus on revealing the origin of quantum decoherence in molecular nanomagnets using unique magnetic resonance techniques to significantly improve quantum coherence. Furthermore, the project incorporates educational activities including research training and curriculum developments for USC graduate and undergraduate students as well as science experiences and outreach activities for high school and elementary school students in the neighborhood community of USC with a high concentration of under-represented population in STEM fields.
Technical Abstract:
This project aims to investigate and control quantum coherence in molecular nanomagnets. Quantum decoherence has become one of the most pressing problems in many solid-state spin systems. Among the solid-state systems, molecular nanomagnets are excellent testbed for understanding nanomagnetism and for applications to dense magnetic storage and quantum spintronics devices because of their nanoscale size, quantum nature in the magnetism, physical and chemical stability, and capability to tune the magnetic properties and couplings to surrounding environments. In this research project, the principle investigator plans to investigates the nature of quantum decoherence in molecular magnets using novel magnetic resonance techniques to demonstrate long quantum coherence. Success in the proposed work will provide a promising pathway for developing molecular nanomagnets with desired coherent properties and setting a general platform for future science on molecular nanomagnet-based spin devices. Furthermore, the project incorporates educational activities including research training and curriculum developments for USC graduate and undergraduate students as well as science experiences and outreach activities for high school and elementary school students in the neighbourhood community of USC with a high concentration of under-represented population in STEM fields.

Demonstration and Applications of Single Molecule Magnetic Resonance Spectroscopy At Physiological Conditions @ University of Southern California
With support from the Chemical Measurement & Imaging (CMI) and the Chemical Structure, Dynamics, & Mechanisms - A (CSDM-A) Programs in the Division of Chemistry, Dr. Susumu Takahashi and his group at the University of Southern California are devising means of improving magnetic resonance (MR) techniques in order to enable application of these powerful characterization tools to study the structure and dynamics of biological molecules down to the level of single molecules. Dr. Takahashi is also developing educational/training programs and materials that will help explain these methods and the chemistry they help to explain to USC graduate and undergraduate students, as well as to high school and elementary school students in USC's neighborhood community.
Magnetic resonance spectrometry techniques, such as nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR), can provide detailed information about molecular structure and dynamics, but are hampered by intrinsically low sensitivity. Recent technological advances, particularly those utilizing a single nitrogen-vacancy (NV) center in diamond as a sensor, have enabled detection of a single electron spin. Dr. Takahashi seeks to demonstrate MR analysis of a few molecules under physiological conditions using NV centers and high-frequency/high-field EPR. Success in the research work will provide a promising pathway to enable EPR investigation of single biological molecules containing either native electron spin centers or extrinsic spin labels.

Investigation and Application of Pulse Shaping to High-Frequency Electron Paramagnetic Resonance (Epr) / Zero-Field Optically Detected Magnetic Resonance (Odmr) Spectroscopy @ University of Southern California
With support from the Chemistry/Chemical Measurement & Imaging and Physics/Quantum Information Sciences programs, Professor Takahashi and his group at the University of Southern California are improving magnetic resonance spectroscopic techniques - important tools for characterizing the structure and motions/changes (dynamics) of chemical systems. They are working to improve our understanding and control of the energy states of matter in order to enhance the sensitivity and level of detail with which chemical systems can be probed. Professor Takahashi is also developing programs to train graduate and undergraduate students in the principles of quantum information science, magnetic resonance spectrometry, and nanotechnology. The team enhances programs of science, technology, engineering and math (STEM) education for high school and elementary school students in the South Los Angeles community.
Pulsed electron paramagnetic resonance (EPR) spectroscopy can provide detailed information about molecular structure and dynamics. Like nuclear magnetic resonance spectroscopy, pulsed EPR spectroscopy becomes more powerful at high magnetic fields and frequencies. The spectral resolution, spin polarization, sensitivity, and time resolution of pulsed EPR all increase with increasing magnetic field and the associated Larmor precession frequency. However, the measurement science of high field/frequency pulsed EPR has yet to be explored due to technological challenges. In this project, Professor Takahashi is utilizing a high-speed arbitrary waveform generator (AWG) for improvement of quantum control and investigation of the measurement science and applications of AWG-driven pulsed EPR at high fields and frequencies.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
