Solid State Physics

An 18-month full-time postdoctoral appointment in the ANR TAME project on topotactic reduction of rare-earth nickelate thin films. Grow heterostructures by pulsed-laser deposition, tune their oxygen content, and investigate structural and electronic changes using X-ray diffraction and synchrotron experiments. Collaborate with theorists on charge ordering and functional properties relevant to neuromorphic materials. The advertised start is 14 October 2026; applications close on 9 October at 23:59.

NIMS is recruiting several permanent researchers for fundamental, foundational and applied materials research. Priority areas include hydrogen and battery materials, quantum and semiconductor materials, magnetic and structural materials, inorganic nanomaterials, polymers and biomaterials, data-driven materials development and advanced characterization. The appointment is expected to begin on 1 April 2027, subject to discussion.

Conduct independent theoretical research complementing the institute’s work, including biological physics of cells and tissues, quantitative biology and physics of life. The call also covers quantum, statistical, condensed-matter and non-equilibrium physics and welcomes promising new directions. Apply by 13 November 2026 with one PDF containing a cover letter, CV, publications highlighting three key papers, research interests and a proposal. Arrange three reference letters separately.

Carolina Paiva develops exact matrix product states for strongly interacting electrons in lattice bands. Conformal-field-theory correlation functions already provide exact representations of fractional quantum Hall trial wavefunctions, including Laughlin states. Extending the construction to fractional Chern insulators is obstructed by the lattice length scale. The talk shows how ideal Chern bands overcome that obstruction and derives an exact representation of Laughlin model states in a hybrid Wannier basis on a torus.

Investigate quantum materials for sensing, including nitrogen-vacancy centers in diamond, with the NIMS Semiconductor Defect Design Group. Work includes electron-spin-resonance characterization of color centers, crystal processing to control their structures, and analysis of defects and impurities. One position with a negotiable start in January 2027 or later. The initial appointment is for one year, renewable after annual review up to five years; published monthly salary JPY 345,425. Applications are accepted until the position is filled. Upload a ZIP through the official role page’s Box link containing the NIMS-format CV with photograph, a one-to-two-page research summary, publications and invited talks, details of two referees and three main papers. Follow the upload form’s subsequent notification instructions.

Study lithium-ion transport in oxide solid electrolytes and all-solid-state batteries, connecting atomic and nanoscale diffusion with crystal structure, local structure, ion correlations and ionic conductivity. Methods include solid-state NMR, pulsed-field-gradient and two-dimensional exchange NMR, impedance spectroscopy and tracer diffusion. Research emphasizes garnet-type oxides and correlated or cooperative ion motion. One position in the Solid State Battery Ionics Group at NIMS; start 1 October 2026 or later. Initial term one year, with annual review and a maximum of five years. Published monthly salary starts at JPY 448,816, depending on experience. Applications are accepted until a qualified candidate is found. The official role page explains how to send the NIMS CV with photograph and a one-page research summary to the named recruitment contact.
