Supersolid phases of a doped valence-bond quantum antiferromagnet: Evidence for a coexisting superconducting order parameter
Marcin Raczkowski, Didier Poilblanc
Motivated by numerical evidence of the valence bond groundstate of the two-dimensional Heisenberg pyrochlore lattice, we argue using a - model that it evolves under doping in…

Unidirectional Charge Instability of the d-wave RVB Superconductor
Marcin Raczkowski, Manuela Capello, Didier Poilblanc
Starting from a uniform d-wave superconducting phase we study the energy cost due to imposed unidirectional defects with a vanishing pairing amplitude. Both renormalized mean-field…

Effect of the next-nearest neighbor hopping on the stability and band structure of the incommensurate phases in the cuprates
Marcin Raczkowski, Raymond Fresard, Andrzej M. Oles
Using a spin-rotation invariant version of the slave-boson approach we investigate the relative stability and band structure of various incommensurate phases in the cuprates. Our f…
