Quantum Fisher information in many-photon states from shift current shot noise
Evgenii Barts, Takahiro Morimoto, Naoto Nagaosa
Quantum Fisher information (QFI) sets the ultimate precision of optical phase measurements and reveals multiphoton entanglement, but it is not accessible with conventional photodet…
Magnetic anisotropy from interligand hopping in strongly correlated insulators: application to the magnon spectrum of CrI
Evgenii Barts, Paolo Barone, Maxim Mostovoy
Spin-orbit coupling (SOC) gives rise to complex magnetic states such as spin liquids, skyrmion crystals, and topological spin-wave excitations. We consider exchange interactions in…
Universal symmetry-protected persistent spin textures in nonmagnetic solids
Berkay Kilic, Sergio Alvarruiz, Evgenii Barts +3
The significance of Mendeleev's periodic table extends beyond the classification of elements; it lies in its remarkable predictive power for discovering new elements and properties…
Efficient spin accumulation carried by slow relaxons in chiral tellurium
Evgenii Barts, Karma Tenzin, Jagoda SÅawiÅska
Efficient conversion between charge currents and spin signals is crucial for realizing magnet-free spintronic devices. However, the strong spin-orbit coupling that enables such a c…
