For example, when electron–electron repulsions become very strong, the physics is often simply that... WebIf you excite a strongly correlated system in two steps, the excitation you make in the first step will effect which excitations you can make in the second step in a highly non-trivial way. The excitation you add first has a strong influence on the system and rearranges everything.
WebNov 19, 2001 · We calculate magnetic anisotropy energy of Fe and Ni by taking into account the effects of strong electronic correlations, spin-orbit coupling, and noncollinearity of intra-atomic magnetization. The LDA+U method is used and its equivalence to dynamical mean-field theory in the static limit is emphasized. Both experimental magnitude of magnetic ... WebMar 28, 2024 · Given that the moiré strain can be leveraged to enhance the strength of correlations in two-dimensional heterostructures, the researchers speculate that breaking electron–hole asymmetry via moiré-enhanced correlations can be an exciting alternative pathway to realize exotic quantum phases in twisted two-dimensional heterostructures.
