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…
Exciton-spin interactions in antiferromagnetic charge-transfer insulators
Tatsuya Kaneko, Yuta Murakami, Denis Golež +2
We derive exciton-spin interactions from a microscopic correlated model that captures important aspects of the physics of charge-transfer (CT) insulators to address magnetism assoc…
Electric and magnetic multipoles and bond orders in excitonic insulators
Tatsuya Kaneko, Yukinori Ohta
We study the charge and spin density distributions of excitonic insulator (EI) states in the tight-binding approximation. We first discuss the charge and spin densities of the EI s…
Excitonic Bose-Einstein condensation in Ta2NiSe5 above room temperature
K. Seki, Y. Wakisaka, T. Kaneko +12
We show that finite temperature variational cluster approximation (VCA) calculations on an extended Falicov-Kimball model can reproduce angle-resolved photoemission spectroscopy (A…
