Attractive interactions drive antiparallel dipolar correlations, explaining the redshift to blueshift transition observed in recent experiments.

Here, the authors propose a new concept of nonlinear pure spin current rooted in quantum geometry. A pure spin current carries electron spin sideways without a net charge current in the same direction, making it attractive for low-power devices. They predict a unique property that flipping the built-in electric polarization of a nonmagnetic material can reverse the pure spin current. This flipping behavior is absent in the conventional spin Hall effect, which has impeded potential applications of the spin Hall effect in spintronics for a long time. The systematic survey here identifies five crystal symmetry classes that allow this behavior, and quantum mechanical calculations predict it in five atomically thin ferroelectrics, paving the way for experimental detection and device application. The authors also propose an optical second-harmonic Kerr microscopy test with an estimated measurable signal, providing a practical route to verify electrically programmable, low-dissipation spin transport without magnetic order.

We propose Majorana-assisted nonlocal spin correlation as a manifestation of Majorana nonlocality in quasi-one-dimensional (1D) Kitaev spin liquids. Focusing on the flux-free sector of the Kitaev honeycomb model in a quasi-1D geometry, we uncover its topological nature and show that it hosts Majoran…

Antisite disorder is a crystallographic defect that normally disrupts lattice continuity and dilutes magnetism. However, in some rare cases, instead of being suppressed, the spin order is reconfigured by antisite disorder, the detailed process of which, as well as the microscopic mechanism for the p…

We investigate the emergence of nontrivial topology in a twisted cuprate bilayer described by the Hubbard model in the weak-interaction regime. Our results show that the topological character depends sensitively on the doping level. For $U/t=3.85$, the Chern number assumes a value of $\pm 8$ in the electro…

Symmetry plays a fundamental role in many-body systems, both in and out of equilibrium.

Magnetic suppression of the non-Hermitian skin effect (NHSE) offers a viable route for its control. While the NHSE has been realized in various classical-wave platforms, only pseudomagnetic fields (PMFs), which preserve time-reversal symmetry, can be engineered in such systems; however, their interp…

Spin-orbit coupling (SOC) leads to splitting of otherwise spin-degenerate bands in noncentrosymmetric materials, even if time-reversal symmetry is present. While this gives rise to well-known phenomena such as the Rashba and Dresselhaus effects, various other terms are allowed based on the point gro…
