Open Postdoctoral Researcher Positions at Department of Applied Physics, The University of Tokyo, or Institute for Science and Engineering, Waseda University in Tokyo, Japan

Position Summary

Applications are invited for postdoctoral researcher positions at Department of Applied Physics, the University of Tokyo, or Research Institute for Science and Engineering, Waseda University. The postdoctoral researchers will conduct research on mechanism of strongly correlated superconductivity and nature of strongly-correlated topological materials by taking advantage of large-scale parallel computers with ab-initio electronic structure approaches and/or data-driven approaches based on spectroscopic data provided by collaborations with experimentalists.

Location of Institution

Hongo campus of the University of Tokyo or Nishi-Waseda campus of Waseda University, Tokyo, Japan

Term

One year with a possibility of extension after review up to March 2023

Expected Start Date

From April 1st, 2020 or later

Required Qualification

Ph. D. in a relevant field such as condensed matter theory, and computational physics

Job/Project Description

[1] Research on mechanisms of high-temperature superconductivity, theoretical search for quantum spin liquid phases in topological materials and/or studies on nature of fractional excitations in strongly correlated electron systems. Studies are directed to reveal universality and material-dependent properties by ab-initio exhaustive studies on diverse compounds supplemented by a thorough parameter search to cultivate and control functionalities.

or

[2] Research on mechanisms of superconductivity and topological properties through reliable inference of experimentally hidden properties by utilizing cutting-edge experimental spectroscopic data.

Depending on the research interest of applicants, the following subjects are provided:

• • Comprehensive analyses on ab initio effective Hamiltonians of strongly correlated materials to clarify fundamentals and nature of high-temperature superconductors and/or topological matter by high-accuracy numerical methods (optionally updates, developments and tuning of open-source software HΦ, mVMC, RESPACK and other software to realize large-scale and efficient parallel computation developed by ab initio calculation methods.)

  • Combining machine learning and/or data-driven methods with the above ab initio studies, studies to extract hidden physical quantities such as self-energy and spectral properties of fractional excitations from spectroscopic experimental data.

In this project, ample large-scale parallel computer resource is available. Tight collaborations with expert experimentalists on strongly correlated electron systems for the spectroscopic methods (such as angle-resolved photoemission, scanning tunnel microscope, and resonant inelastic X-ray scattering) are scheduled. Target materials are copper-oxide, iron-based, and other unconventional high-T_c superconductors, and topological materials such as iridium oxides and ruthenium halides.

Applicants who are strongly motivated to work on one or several of the above diverse physical subjects or methodologies are highly welcome.
