Postdoctoral Research Associate Quantum Dynamics

Job ID JR100778 Date posted 12/20/2023

The Coherent Hard X-ray Scattering (CHX) beamline at NSLSII is dedicated to studies of nanometer-scale dynamics in materials using x-ray photon correlation spectroscopy (XPCS) with a state-of-the-art diffraction and detection system for fast dynamics. It has an order of magnitude higher coherent flux and two orders of magnitude wider dynamic range compared to any other beamlines in the US. CHX is seeking a postdoctoral research associate to utilize CHX’s new magnetic resonance capability and sub-4K sample environment to study dynamics in quantum materials. 


The successful candidate will be based at CHX at NSLSII and will study quantum dynamics in topological condensed matter systems using coherent x-rays under the supervision of Xiaoqian Chen. The candidate will also work closely with the X-ray Scattering Group at Condensed Matter Physics and Materials Division (CMPMD).

Essential Duties and Responsibilities:

• Work together with the members of the CHX and the XSG to plan, develop and perform the first XPCS measurements of quantum dynamics in complex oxides using coherent hard x-rays.
• Analyze the prepare data for scientific publications and talks.  

Required Knowledge, Skills, and Abilities:

• PhD in physics, materials science, physical chemistry or related field.
• Good understanding of the physics of quantum materials
• Experience in x-ray scattering or related techniques
• Strong data analysis skills using programs such as Python or related packages  
• Excellent written and oral communication skills including writing academic papers
• Ability to work both independently and as part of a team

Preferred Knowledge, Skills, and Abilities:

• Experience in synchrotron-based experiments
• Experience in coherent x-rays or/and resonant x-ray scattering

Other Information:

  • Brookhaven National Laboratory and the Energy and Photon Sciences Directorate are committed to your success. We offer a supportive work environment and the resources necessary for you to succeed.
  • BNL policy requires that after obtaining a PhD, eligible candidates for research associate appointments may not exceed a combined total of 5 years of relevant work experience as a post-doc and/or in an R&D position, excluding time associated with family planning, military service, illness or other life-changing events.
