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…
Temperature-scaling behavior of the Hall conductivity for Hg-based superconducting thin films
Wan-Seon Kim, W. N. Kang, S. J. Oh +5
The Hall conductivities of HgBa_{2}CaCu_{2}O_{6+δ}and HgBa_{2}Ca_{2}Cu_{3}O_{8+δ} thin films are investigated for a magnetic field parallel to the c axis. The mixed-state Hall cond…
Triple sign reversal of Hall effect in HgBa_{2}CaCu_{2}O_{6} thin films after heavy-ion irradiations
W. N. Kang, B. W. Kang, Q. Y. Chen +6
Triple sign reversal in the mixed-state Hall effect has been observed for the first time in ion-irradiated HgBa_{2}CaCu_{2}O_{6} thin films. The negative dip at the third sign reve…
