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…
Third-harmonic generation in superconductors: Role of quantum geometry in the competition between Higgs mode and quasiparticles
Chang-geun Oh, Haruki Watanabe, Naoto Tsuji
Collective modes in superconductors, such as the Higgs mode, offer deep insights into the nature of condensates. Third-harmonic generation (THG) is a primary tool for probing the H…
Two-dimensional coherent spectroscopy of disordered superconductors in the narrow-band and broad-band limits
Naoto Tsuji
We theoretically analyze two-dimensional coherent spectroscopy (2DCS) signals for disordered superconductors in two limits: One is the narrow-band limit with sinusoidal pulse waves…
Dissipative Kondo physics in the Anderson Impurity Model with two-body losses
Matthieu Vanhoecke, Naoto Tsuji, Marco Schirò
We study a dissipative version of the Anderson Impurity model, where an interacting impurity is coupled to a fermionic reservoir and exposed to Markovian dissipation in the form of…
Higgs and Nambu-Goldstone modes in condensed matter physics
Naoto Tsuji, Ippei Danshita, Shunji Tsuchiya
Collective dynamics of many particle systems is tightly linked to their underlying symmetry and phase transitions. Higgs and Nambu-Goldstone modes are, respectively, collective amp…
