Pair Density Waves in coupled doped two-leg Ladders
Javier Almeida, Guillaume Roux, Didier Poilblanc
Motivated by Resonant X-ray scattering experiments in cuprate ladder materials showing charge order modulation of period and 5 at specific hole densities, we investigate mode…
VBS State Induced by Impurity Frustration in Cr8Ni
J. Almeida, M. A. Martin-Delgado, G. Sierra
We provide a physically meaningful picture of the nature of the ground state of the Cr8Ni compound in the regime where it is a spin singlet. According to this picture, the anisotro…
Twisted Order Parameter applied to Dimerized Ladders
J. Almeida, M. A. Martin-Delgado, G. Sierra
We apply the twisted order parameter (TOP) for dimerized quantum spin ladders to locate the critical phases that separate gapped phases representing quantum spin liquids of various…
Critical Lines and Massive Phases in Quantum Spin Ladders with Dimerization
Javier Almeida, M. A. Martin-Delgado, G. Sierra
We determine the existence of critical lines in dimerized quantum spin ladders in their phase diagram of coupling constants using the finite-size DMRG algorithm. We consider both s…
DMRG study of the Bond Alternating \textbf{S}=1/2 Heisenberg ladder with Ferro-Antiferromagnetic couplings
J. Almeida, M. A. Martin-Delgado, G. Sierra
We obtain the phase diagram in the parameter space and an accurate estimate of the critical line separating the different phases. We show several measuments of the magn…
