Critical Behaviour near the Mott Transition in a Two-Band Hubbard Model
Yasuo Ohashi, Yoshiaki Ōno
The Mott metal-insulator transition in the two-band Hubbard model in infinite dimensions is studied by using the linearized dynamical mean-field theory. The discontinuity in the ch…

Magnetic Excitations of the Spin Gap System TlCuCl
A. Oosawa, T. Kato, H. Tanaka +3
TlCuCl has a singlet ground state with the excitation gap meV. The magnetic excitations in TlCuCl have been investigated by means of neutron inelastic scattering e…

Magnetic Excitations in the Spin Gap System TlCuCl
A. Oosawa, T. Kato, H. Tanaka +5
Single-crystal neutron inelastic scattering was performed in order to investigate the magnetic excitations in the spin gap system TlCuCl. The constant- energy scan pro…
