概要
- 論文の詳細を見る
We study the triangular t-J model with multiple spin exchange interactions using exact diagonalization of small clusters, as a model of monolayer liquid ^3He. A phase where the energy spectrum suggest the behaviors of spin-charge separation is realized in the doped-Mott region due to the competition between ferromagnetic two-spin and antiferromagnetic four-spin exchange interactions. This behavior gives an interpretation of the double peaked heat capacity recently observed in monolayer liquid ^3He adsorbed on a graphite.
