Welcome to Ozawa group at Advanced Institute for Materials Research (AIMR) in Tohoku University!
We are a theoretical physics research group, studying an intersection between condensed matter physics and atomic, molecular, and optical physics.

What's new

  • April 22, 2024: In collaboration with Yoshiro Takahashi lab in Kyoto University, we succeeded in forming Bose-Einstein condensation at a topological edge state. This is the atom version of the topological laser, i.e. topological atom laser. You can read more in our arXiv paper! arXiv:2404.13769
  • April 3, 2024: Collaboration with the Gadway group at the University of Illinois and Pennsylvania State University on Aharonov-Bohm caging with Rydberg atoms is now on arXiv! arXiv:2404.00737
  • April 1, 2024: Tomoki has been promoted to full professor!
  • March 31, 2024: Ryo left the group to join SOLIZE!
  • March 28, 2024: We have proven a new type of bulk-edge correspondence, which we call bulk-entanglement-spectrum correspondence, for topological insulators with PT or PC symmetry. Please check our paper on arXiv! arXiv:2403.18372
  • March 15, 2024: Tomoki has received Marubun Research Encouragement Award from Marubun Research Promotion Foundation!
  • March 7, 2024: With Nathan Goldman from Bruxelles, we wrote a pedagogical note explaining the relation between the many-body Chern number and the Hall conductivity. You can read it on arXiv! arXiv:2403.03340
  • March 1, 2024: Bruno's collaboration with experimentalists on quantum metrology is accepted for publication in National Science Review!
  • February 9, 2024: The paper on a charged particle in a two-dimensional lattice under an imaginary magnetic field is published in Physical Review B! Phys. Rev. B 109, 085113 (2024)
  • February 1, 2024: Tomoki selected as the recipient of the 6th Teruo Hiruma Photonics Award by Research Foundation for Opto-Science and Technology!
  • January 17, 2024: Ryo's collaboration on non-Hermitian skin effect under nonsymmorphic symmetries is published in Physical Review B! Phys. Rev. B 109, 035131 (2024)
  • January 9, 2024: The paper in which we studied properties of a discrete nonlinear Schrödinger equation coupled to density-dependent gauge field is now published in Physical Review Letters! Phys. Rev. Lett. 132, 023401 (2024)
