Brookhaven National Laboratory is seeking an experimental postdoctoral researcher to develop and perform ultrafast nonlinear spectroscopies of quantum materials, focusing on multi-dimensional spectroscopies in the terahertz to optical frequency ranges. The goal is to study the properties of strongly correlated electron systems, topological materials, and low-dimensional nanostructures, both in equilibrium and non-equilibrium states, and to disseminate research findings.

Requirements

  • Demonstrated data analysis skills.
  • Extensive experience building free-space optical setups.
  • Extensive experience with ultrafast laser systems.
  • Demonstrated experience with mJ-class ultrafast laser amplifiers, using ultrafast optical parametric amplifiers, building ultrafast optical parametric amplifiers, cryogenic systems, and generating and using intense mid- and far-infrared light pulses.
  • Knowledge of nonlinear optical phenomena in condensed matter systems.
  • Experience in developing software to run ultrafast spectroscopy experiments.
  • A good understanding of light-matter interactions in condensed matter systems

Responsibilities

  • Responsible for setting up a multi-dimensional terahertz spectrometer, using ultrafast laser amplifiers as a light source.
  • Responsible for using a home-built multi-dimensional terahertz spectrometer and a commercial multi-dimensional optical spectrometer towards studying the properties of varied “quantum materials”.
  • This will involve coordinating experimental acquisition and subsequent analysis of data.
  • Responsible for disseminating research results in the form of conference presentations and writing of publications.

Other

  • PhD. in Physics or related discipline.
  • Demonstrated written and oral communication skills in English, be self-motivated and able to work both independently and as a part of a multi-institutional team.
  • Ability to interact effectively with a diverse group of scientists and technical staff.
  • Proven ability to disseminate research results.
  • Able to work closely and communicate effectively with colleagues focused on other experimental and theoretical techniques.
