    • Ising-nematic order in the bilinear-biquadratic model for the iron pnictides 

      Ergueta, Patricia Bilbao; Nevidomskyy, Andriy H. (2015)
      Motivated by the recent inelastic neutron scattering (INS) measurements in the iron pnictides which show a strong anisotropy of spin excitations even above the magnetic transition temperature TN, we study the spin dynamics ...
    • Unified spin model for magnetic excitations in iron chalcogenides 

      Ergueta, Patricia Bilbao; Hu, Wen-Jun; Nevidomskyy, Andriy H. (2017)
      Recent inelastic neutron scattering (INS) measurements on FeSe and Fe(Te1−xSex) have sparked intense debate over the nature of the ground state in these materials. Here we propose an effective bilinear-biquadratic spin ...
