Dirac Electrons in AC-Magnetic Fields: -Landau Levels and Chiral Anomaly-Induced Homodyne Effect
Sota Kitamura, Takashi Oka
Floquet engineering, which involves controlling systems through time-periodic driving, is a method for coherently manipulating quantum materials and realizing dynamical states with…
Magnetism and Topology from Circularly Polarized Phonon Floquet Engineering
Dapeng Yao, Tiantian Zhang, Takashi Oka +1
We theoretically show that circularly polarized phonons induce electronic magnetization and drive a topological phase transition via phonon Floquet engineering. Considering the ele…
Direct probing the quantum geometric tensor for bosonic collective excitations
Chi Wu, Takashi Oka, Shuichi Murakami +1
The quantum geometric tensor (QGT), whose real and imaginary parts define the quantum metric and Berry curvature, encodes the intrinsic geometry of quantum states. While electronic…
Long-range electron coherence in Kagome metals
Chunyu, Guo, Kaize Wang +17
The wave-like nature of electrons lies at the core of quantum mechanics, distinguishing them from classical particles. Landmark experiments have revealed phase coherence of mobile…
