    • Condensation of magnons and spinons in a frustrated ladder 

      Fouet, J.-B.; Mila, F.; Clarke, D.; Youk, H.; Tchernyshyov, O.; Fendley, P.; Noack, R.M. (American Physical Society, 2006-06-01)
      Motivated by the ever-increasing experimental effort devoted to the properties of frustrated quantum magnets in a magnetic field, we present a careful and detailed theoretical analysis of a one-dimensional version of this ...
    • Ising phases of Heisenberg ladders in a magnetic field 

      Penc, K.; Fouet, J.-B.; Miyahara, S.; Tchernyshyov, O.; Mila, F. (American Physical Society, 2007-09-14)
      We show that Dzyaloshinskii-Moriya (DM) interactions can substantially modify the phase diagram of spin-1/2 Heisenberg ladders in a magnetic field provided they compete with exchange. For nonfrustrated ladders, they induce ...
