In this work, we present three unconventional electronic mechanisms of electronic phase separation (EPS) in a 2DEG as a possible source of inhomogeneity in oxide interfaces. Common to all three mechanisms is the dependence of some (interaction) potential on the 2DEGs density. We first consider a mechanism resulting from a sizable density-dependent Rashba spin-orbit coupling. Next, we point out that an EPS may also occur in the case of a density-dependent superconducting pairing interaction. Finally, we show that the confinement of the 2DEG to the interface by a density-dependent, self-consistent electrostatic potential can by itself cause an EPS.}, language = {en} } @misc{SeiboldCapraraGrillietal., author = {Seibold, G{\"o}tz and Caprara, Sergio and Grilli, Marco and Raimondi, Roberto}, title = {On the Evaluation of the Spin Galvanic Effect in Lattice Models with Rashba Spin-Orbit Coupling}, series = {Condensed matter}, volume = {3}, journal = {Condensed matter}, number = {33}, issn = {2410-3896}, doi = {10.3390/condmat3030022}, pages = {1 -- 10}, abstract = {The spin galvanic effect (SGE) describes the conversion of a non-equilibrium spin polarization into a charge current and has recently attracted renewed interest due to the large conversion efficiency observed in oxide interfaces. An important factor in the SGE theory is disorder which ensures the stationarity of the conversion. Through this paper, we propose a procedure for the evaluation of the SGE on disordered lattices which can also be readily implemented for multiband systems. We demonstrate the performance of the method for a single-band Rashba model and compare our results with those obtained within the self-consistent Born approximation for a continuum model.}, language = {en} } @article{SeiboldGrilli, author = {Seibold, G{\"o}tz and Grilli, Marco}, title = {Influence of incommensurate dynamic charge-density wave scatteringon the line shape of superconducting high-Tc cuprates}, series = {Physical Review B}, volume = {63}, journal = {Physical Review B}, number = {22}, issn = {1550-235X}, pages = {224505}, language = {en} } @article{SeiboldGrilli, author = {Seibold, G{\"o}tz and Grilli, Marco}, title = {Theory of isotope dependence of photoemission spectra ofhigh-Tc superconducting cuprates}, language = {en} } @misc{SeiboldGrilliLorenzana, author = {Seibold, G{\"o}tz and Grilli, Marco and Lorenzana, A.}, title = {Dynamics of Electronic Inhomogeneities in Cuprates}, language = {en} } @misc{SeiboldCapraraGrillietal., author = {Seibold, G{\"o}tz and Caprara, Sergio and Grilli, Marco and Raimondi, Roberto}, title = {Intrinsic spin Hall effect in systems with striped spin-orbit coupling}, series = {epl : a letters journal exploring the frontiers of physics}, volume = {112}, journal = {epl : a letters journal exploring the frontiers of physics}, number = {1}, issn = {1286-4854}, doi = {http://dx.doi.org/10.1209/0295-5075/112/17004}, pages = {17004-p1 -- 17004-p6}, language = {en} } @misc{SeiboldGrilli, author = {Seibold, G{\"o}tz and Grilli, Marco}, title = {Influence of incommensurate dynamic charge-density wave scattering on the line shape of supersonducting high-Tc cuprates}, series = {Physical review : B}, journal = {Physical review : B}, number = {22}, issn = {1098-0121}, pages = {S. 224505}, language = {en} } @misc{SeiboldCapraraGrillietal., author = {Seibold, G{\"o}tz and Caprara, Sergio and Grilli, Marco and Raimondi, Roberto}, title = {Theory of the Spin Galvanic Effect at Oxide Interfaces}, series = {Physical Review Letters}, volume = {119}, journal = {Physical Review Letters}, number = {25}, issn = {1092-0145}, doi = {10.1103/PhysRevLett.119.256801}, abstract = {The spin galvanic effect (SGE) describes the conversion of a nonequilibrium spin polarization into a transverse charge current. Recent experiments have demonstrated a large conversion efficiency for the two-dimensional electron gas formed at the interface between two insulating oxides, LaAlO3 and SrTiO3. Here, we analyze the SGE for oxide interfaces within a three-band model for the Ti t2g orbitals which displays an interesting variety of effective spin-orbit couplings in the individual bands that contribute differently to the spin-charge conversion. Our analytical approach is supplemented by a numerical treatment where we also investigate the influence of disorder and temperature, which turns out to be crucial to providing an appropriate description of the experimental data.}, language = {en} }
