A new paradigm of non-Hermitian quantum mechanics

  • 1.5 Quantum interdisciplinary sciences(Life science, Mathematics, Particle physics, Space science, Astronomy, Quantum gravity, etc.)
  • 2.3 Quantum materials(Topological materials/Thermoelectric devices/Functional materials)
Naomichi Hatano
Institute of Industrial Science
Department of Fundamental Engineering Professor
We pursue novel phenomena theoretically by generalizing the Hamiltonian, which is set to be a Hermitian operator in the standard quantum mechanics, to a non-Hermitian one.
We also try to propose experiments that possibly confirms non-Hermitian quantum mechanics.
A classical statistical-mechanical model from which Hatano introduced a non-Hermitian quantum system in 1996. A type-II superconductor contains columnar defects and magnetic flux.
