Many-body calculation of the spatial extent of the wave-function of a non-magnetic impurity in a d-wave high-temperature superconductor using the t--J model
Manuela Capello, Didier Poilblanc
Scanning tunneling microscopy (STM) by providing images of the effects of individual zinc-impurities in cuprate superconductors with unprecedented atomic-resolution offers a string…
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…
Mott transition in bosonic systems: Insights from the variational approach
Manuela Capello, Federico Becca, Michele Fabrizio +1
We study the Mott transition occurring for bosonic Hubbard models in one, two, and three spatial dimensions, by means of a variational wave function benchmarked by Green's function…
Stability of RVB hole stripes in high-temperature superconductors
Manuela Capello, Marcin Raczkowski, Didier Poilblanc
Indications of density-wave states in underdoped cuprates, coming from recent STM (scanning tunneling microscopy) and Hall-resistance measurements, have raised new concerns whether…
Unidirectional d-wave superconducting domains in the two-dimensional t-J model
Marcin Raczkowski, Manuela Capello, Didier Poilblanc +2
Motivated by the recently observed pattern of unidirectional domains in high-T_c superconductors [Y. Kohsaka et al., Science 315, 1380 (2007)], we investigate the emergence of spon…
Superfluid to Mott-insulator transition in Bose-Hubbard models
Manuela Capello, Federico Becca, Michele Fabrizio +1
We study the superfluid-insulator transition in Bose-Hubbard models in one-, two-, and three-dimensional cubic lattices by means of a recently proposed variational wave function. I…
