Connecting Density Matrix Spectroscopy to Biexciton Entanglement Dynamics
Yusuke Masaki, Takashi Otaki, Hiroaki Matsueda
Quantum entanglement is one of the most intriguing features of quantum mechanics. To investigate the entanglement between two excitons in a biexciton, an experimental technique cal…
Circuit-based cavity magnonics in the ultrastrong and deep-strong coupling regimes
Takahiro Chiba, Ryunosuke Suzuki, Takashi Otaki +1
We theoretically study nonperturbative strong-coupling phenomena in cavity magnonics systems in which the uniform magnetization dynamics (magnons) in a ferromagnet is coupled to th…
Exact-Diagonalization Analysis of Composite Excitations in the t-J Model
Takashi Otaki, Yuta Yahagi, Hiroaki Matsueda
We examine spectral properties of doped holes dressed with surrounding spin cloud in the t-J model. These composite-hole excitations well characterize prominent band structures in…
