Shift of quantum critical point of discrete time crystal on a noisy quantum simulator
Yuta Hirasaki, Toshinari Itoko, Naoki Kanazawa +1
Recent advances in quantum technology have enabled the simulation of quantum many-body systems on real quantum devices. However, such quantum simulators are inherently subject to d…
Field Dispersion and Strong Coupling of Nuclear-Electron Spin Excitation in MnCO
Takahiko Makiuchi, Takashi Kikkawa, Thanaporn Sichanugrist +5
Hybridized nuclear and electron spin excitation in a MnCO crystal, a weakly-anisotropic antiferromagnet, has been investigated. In this material, the hyperfine interaction is s…
Current-induced magnon trapping in spin torque oscillation
Takahiko Makiuchi, Naoki Kanazawa, Eiji Saitoh
Spin torque nano-oscillators realized by magnetization dynamics trapped in a current-induced potential are reported. We fabricated NiFe/Pt nanostructures and measured…
Dynamics of measurement-induced state transitions in superconducting qubits
Yuta Hirasaki, Shunsuke Daimon, Naoki Kanazawa +3
We have investigated temporal fluctuation of superconducting qubits via the time-resolved measurement for an IBM Quantum system. We found that the qubit error rate abruptly changes…
Detecting bulk carbon ferromagnetism in graphene multi-edge structure
Chao Wang, Nan Jian, Meijie Yin +11
The emergence of bulk carbon ferromagnetism is long-expected over years. At nanoscale, carbon ferromagnetism was detected by analyzing the magnetic edge states via scanning tunneli…
