About

Ian R. Fisher is a Humanities and Sciences Professor, Professor and Chair of Applied Physics, and Professor, by courtesy, of Materials Science and Engineering at Stanford University. His research group is based in the Geballe Laboratory for Advanced Materials at Stanford, where they study materials with unconventional magnetic and electronic properties. The broad aim of his research is to obtain a deeper understanding of the many effects that can emerge from electron correlation. His team employs techniques to grow high-quality single crystals of materials of interest and conducts experiments to probe the thermodynamic and transport properties of these materials, often in high magnetic fields. Current research interests include superconductivity, electronic nematic order, aspects of quantum magnetism, and the behavior of electrons in low-dimensional materials.

• Nonequilibrium charge-density-wave order beyond the thermal limit

  Nature Communications · 2021 · 54 citations

  The interaction of many-body systems with intense light pulses may lead to novel emergent phenomena far from equilibrium. Recent discoveries, such as the optical enhancement of the critical temperature in certain superconductors and the photo-stabilization of hidden phases, have turned this field into an important research frontier. Here, we demonstrate nonthermal charge-density-wave (CDW) order at electronic temperatures far greater than the thermodynamic transition temperature. Using time- and…

• Measurement of the magnetic octupole susceptibility of PrV2Al20

  Nature Communications · 2024-08-14 · 13 citations

  articleOpen accessSenior author

  Revealing the presence of magnetic octupole order and associated octupole fluctuations in solids is a highly challenging task due to the lack of simple external fields that can couple to magnetic octupoles. Here, we demonstrate a methodology for probing the magnetic octupole susceptibility of a candidate material, PrV2Al20, using a product of magnetic field Hi and shear strain ϵjk as a composite effective field, while employing an adiabatic elastocaloric effect to probe the response. We observe…

• Dark-field X-ray microscopy with structured illumination for three-dimensional imaging

  Communications Physics · 2025-01-22 · 7 citations

  articleOpen access

  Abstract Dark-field X-ray microscopy is a lens-based technique that enables real-space imaging of heterogeneous micro- and meso-scale ordered materials. However, achieving accurate three-dimensional (3D) reconstruction often requires meticulous sample alignment or rastering, requiring complex rotational setups and extended acquisition times. To address these challenges, we introduce a structured illumination technique optimized for 3D imaging of ordered materials at sub-micrometer length scales.…
