Time-dependent Gutzwiller theory of pairing fluctuations in the Hubbard model
G. Seibold, F. Becca, J. Lorenzana
We present a method to compute pairing fluctuations on top of the Gutzwiller approximation (GA). Our investigations are based on a charge-rotational invariant GA energy functional…
Phase diagram for Coulomb-frustrated phase separation in systems with negative short-range compressibility
C. Ortix, J. Lorenzana, C. Di Castro
Using numerical techniques and asymptotic expansions we obtain the phase diagram of a paradigmatic model of Coulomb frustrated phase separation in systems with negative short-range…
Coarse grained models in Coulomb-frustrated phase separation
C. Ortix, J. Lorenzana, C. Di Castro
Competition between interactions on different length scales leads to self-organized textures in classical as well as quantum systems. This pattern formation phenomenon has been inv…
Intermediate scale phenomena in cuprates
J. Lorenzana, G. Seibold
After 20 years of research the low energy physics of cuprates remains a mystery. It is generally accepted that a three band Hamiltonian with Cu's and O's orbitals should contain th…
Magnetization of La(2-x)Sr(x)NiO(4+ delta) (0 < x < 0.5) and observation of novel memory effects
P. G. Freeman, A. T. Boothroyd, D. Prabhakaran +1
We have studied the magnetization of a series of spin-charge ordered La(2-x)Sr(x)NiO(4+delta) single crystals with 0 < x < 0.5. For fields applied parallel to the ab plane there is…
First principle computation of stripes in cuprates
V. I. Anisimov, M. A. Korotin, A. S. Mylnikova +2
We present a first principle computation of vertical stripes in within the LDA+U method. We find that Cu centered stripes are unstable toward O centered st…
