Topological Excitations in Doped Spin Ladders

Yujoung Bai

We study low-energy magnetic excitations of doped spin-ladders, based on an effective Hamiltonian describing interactions of mobile spin and background spins. The helicity modulus…

Phases from Lightly-Doped Two-Legged Spin Ladders

Yujoung Bai, Sung-Ik Lee

We study two-leg spin ladder systems analytically by using a t-J model which includes the interchain spin exchange and the interchain hopping term. The spin part is mapped to a qua…
