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…
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…
Role of Quantum Geometry in the Competition between Higgs Mode and Quasiparticles in Third-Harmonic Generation of Superconductors
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…
Dissipative Kondo physics in the Anderson Impurity Model with two-body losses
Matthieu Vanhoecke, Naoto Tsuji, Marco Schirò +1
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…
