Generating collective spin cat states via photon-number measurements near the Dicke critical point
Taiga Nakamoto, Shohei Imai, Kazuaki Takasan
We propose a method for generating collective spin cat states in a cavity-coupled atomic ensemble by exploiting strong light-matter entanglement and anti-squeezing associated with…

Photoemission Signatures of Photoinduced Carriers and Excitons in One-Dimensional Mott Insulators
Taiga Nakamoto, Yuta Murakami, Naoto Tsuji
We theoretically study photoemission spectra for photodoped one-dimensional Mott insulators that can host excitons, and show that their spectral characteristics differ qualitativel…
