Interaction-driven dynamics in graphene flakes as a benchmark for quantum simulation
Fabian Eickhoff, Satoshi Ejima, Lukas Windgätter +4
We study interaction-driven ultrafast dynamics in finite graphene flakes following an optical pump quench in an interacting tight-binding model. By comparing exact real-time evolut…
Correlation-driven branch in doped excitonic insulators
Tatsuya Kaneko, Ryota Ueda, Satoshi Ejima
We investigate the spectral properties of doped one-dimensional excitonic insulators. Employing matrix-product-state-based methods, we compute the single-particle spectrum and opti…
Dynamical correlation functions for the one-dimensional Bose-Hubbard insulator
Kevin zu Münster, Florian Gebhard, Satoshi Ejima +1
We calculate the dynamical current and kinetic-energy correlation functions for the first Mott lobe of the one-dimensional Bose-Hubbard model. We employ the strong-coupling expansi…
Ground-State Properties of the - Model for the CuO Double-Chain Structure
Tatsuya Kaneko, Satoshi Ejima, Koudai Sugimoto +1
We investigate the ground-state properties of a correlated model for the double-chain structure in cuprates. We consider the - model, in which the nearest-neighbor spin inter…
Pump-probe spectroscopy of the one-dimensional extended Hubbard model at half filling
Koudai Sugimoto, Satoshi Ejima
By utilizing time-dependent tensor-network algorithms in the infinite matrix-product-state representation, we theoretically investigate the pump-probe spectroscopy of the one-dimen…
Photoinduced pairing in Mott insulators
Satoshi Ejima, Holger Fehske
Utilizing time-evolution techniques in (infinite) matrix-product-state representation, we study the non-equilibrium dynamics of driven Mott insulators and demonstrate photoinduced…
