Mechanism of the reorientation of stripes in the cuprates
Marcin Raczkowski, Raymond Fresard, Andrzej M. Oles
Using the mean field theory in the slave-boson approach we analyzed the electron correlation effects in the stripe phases. One finds that a finite next-nearest neighbor hopping $t'…
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…
Magnetic and orbital correlations in a two-site molecule
Marcin Raczkowski, Raymond Fresard, Andrzej M. Oles
We analyze the role of orbital degeneracy in possible magnetic and orbital instabilities by solving exactly a two-site molecule with two orbitals of either or symmet…
Spin-rotationally symmetric domain flux phases in underdoped cuprates
Marcin Raczkowski, Didier Poilblanc, Raymond Fresard +1
We propose a new form of inhomogeneous phases consisting of out-of-phase staggered flux domains separated by diagonal charged domain walls centered on bonds or on sites. Remarkably…
Interplay between incommensurate phases in the cuprates
Marcin Raczkowski, Raymond Fresard, Andrzej M. Oles
We establish the qualitative behavior of the incommensurability , optimal domain wall filling and chemical potential for increasing doping by a systematic slave-boson st…
Slave-boson approach to the metallic stripe phases with large unit cells
Marcin Raczkowski, Raymond Fresard, Andrzej M. Oles
Using a rotationally invariant version of the slave-boson approach in spin space we analyze the stability of stripe phases with large unit cells in the two-dimensional Hubbard mode…
