Hayami Group

We theoretically study novel physical phenomena in strongly-correlated electron systems based on quantum mechanics and statistical physics.
Our recent research subjects include
  • Classification of electronic physical properties based on microscopic augmented multipoles
  • Cross-correlated phenomena over electric, magnetic, elastic, heat, and light
  • Understanding physical phenomena induced by toroidal orderings
  • Novel off-diagonal response caused by ferro-axial moment
  • Emergent spin-orbit intearction in magnetic systems without the relativistic spin-orbit coupling
  • Magnetic skyrmion crystals by itinerant frustration
  • Generation of skyrmion crystals by using multi-layer structures
  • Search for novel topological magnetic phases in itinerant magnets
  • Peculiar electornic and magnetic states in spin-charge coupled systems
  • Stabilization mechanism and dynamics in magnetic skyrmion and vortex in localized spin system
  • Photo-induced quantum states of matter and physical phenomena
  • Microscopic mechanism of nonreciprocal magnon excitations
  • Search for function materials toward antiferromagnetic spintronics
  • Novel magnetic states by geometrical frustration
  • Analysis of unconventional electronic orderings and physical phenomena discovered in real materials
