A Theoretical study of the ground state phase transition of S=1/2 4-leg spin ladder system

Hijii, Keigo; Sakai, Toru

We investigate ground states of the S=1/2 4-leg frustrated spin ladder system. We find a sign of a quantum phase transition using twisted boundary condition method and the conformal field theory. We will report a finding about the quantum phase in the ground state.
