Mutual Exclusion Statistics in the Exactly Solvable Model of the Mott Metal-Insulator Transition
Yasuhiro Hatsugai, Mahito Kohmoto, Tohru Koma +1
We study statistical characterization of the many-body states in the exactly solvable model with internal degree of freedom in more than one dimension. The model exhibits the Mott…

Mutual Exclusion Statistics in Exactly Solvable Models in One and Higher Dimensions at Low Temperatures
Y. Hatsugai, M. Kohmoto, T. Koma +2
We study statistical characterization of the many-body states in exactly solvable models with internal degrees of freedom. The models under consideration include the isotropic and…
