Research interests

Condensed matter physics and chemistry

  • Spin liquids and spin ices, especially in rare-earth pyrochlores with quantum fluctuations

  • Complex magnetic orders and spin dynamics arising from competing interactions

  • Preparation and crystal chemistry of novel materials with strong magnetic fluctuations (complex oxides, metal-organic frameworks, intermetallics)
