Condensed Matter Physics Postdoc;

Position: Condensed Matter Physics Postdoc (Multiple Openings)
** What You Will Do*
* The Pulsed Field Facility of the National High Magnetic Field Laboratory ((Use the "Apply for this Job" box below).)  (NHMFL) at Los Alamos National Laboratory has an immediate opening for 3 postdoctoral positions in experimental condensed matter physics in high magnetic fields, each focusing on the following areas:

+ Position #1:  Magneto-optical spectroscopy of semiconducting, magnetic, and superconducting materials.  Inquiries should be sent to Dr. Scott Crooker (crooker)

+ Position #2 :
Thermal transport techniques, including specific heat and thermoelectric effects. This position offers opportunities to design and develop novel instrumentation, as well as to study thermal transport properties in both bulk crystals and thin films. The project aims to deepen understanding of phase transitions and the electronic behavior of quantum materials such as quantum spin liquids and topological semimetals. Inquiries regarding this position should be directed to Drs.

KM Rubi (rubi) and Minseong Lee (ml10k)

+ Position #3:
Experimental studies of unconventional superconductivity and quantum magnetism using resonant ultrasound spectroscopy, pulsed-echo techniques, and resonant magnetometry. Inquiries about this position should be directed to Dr. Chris Mizzi (mizzi ) and Dr. Arkady Shekhter (ark).

The NHMFL is a user facility for research in materials, chemistry, and life sciences. The Pulsed Field Facility is dedicated to providing the largest non-destructive magnetic fields for research. The positions also provide opportunities for industrious candidates to pursue new collaborations, develop complementary techniques, and perform independent research within related topics at LANL.
