“Discovering Quantum Anomalies Through Strain” Ultrafast Optical Characterization Postdoctoral Research Associate

What You Will Do

The Center for Integrated Nanotechnologies (MPA-CINT) is seeking outstanding postdoctoral candidates to join the "Discovering Quantum Anomalies through Strain" project team at Los Alamos National Laboratory. Experimental positions will interface strongly with the theoreticians in the Physics of Condensed Matter and Complex Systems Group (T-4), and other experimentalists in the National High Magnetic Field - Pulsed Field Facility (MPA-MAGLAB) and Quantum Group (MPA-Q). The large interdisciplinary project combines materials informatics, strain-based characterization, high magnetic fields, and ultrafast optics to quantitatively predict and experimentally isolate signatures of quantum anomalies in condensed matter, through experiments that are unique to LANL experimental capabilities. The postdocs will investigate Dirac semi-metals, a new class of topological quantum materials whose band structure can be tuned using strain.

Three important symmetries that exist in classical field theory are broken when translated to the quantum regime. These are called scale (or "conformal"), axial (or "chiral"), and parity quantum anomalies. This project consists of three topics that combine condensed matter theory and experiment to identify signatures of these anomalies in condensed matter systems: (1) integrated materials informatics-driven synthesis to enhance signatures of quantum anomalies, (2) MEMS-based high magnetic field thermal transport measurements, and (3) dynamic ultrafast optical measurements including time-resolved ARPES.

The Ultrafast Optical Characterization Postdoc will aid in the development of time-resolved ARPES capability and will perform work using femto-second pulsed excitation to tune the band dispersion and demonstrate optical and strain control over transport including the quantum anomalous Hall effect.

The successful candidate(s) will contribute to a one-of-a-kind collaborative team environment consisting of accomplished early, mid, and senior career scientists in fabrication of magneto-thermoelectric MEMS platforms, quantum materials synthesis, contacts and device processing, quantum materials theory, strain-tuned transport, high magnetic field experimentation, and ultrafast optical characterization.

Being part of this highly multidisciplinary team, the successful applicant(s) will have the chance to be part of a project with far-reaching implications for quantum effects leading to high profile publications. The success of this project will also contribute to applications in micro-bolometry, THz polarization state control, and robust quantum computing.
