Type-II quadrupole topological insulators
Physical Review Research, 2020 Modern theory of electric polarization is formulated by the Berry phase, which, when quantized, leads to topological phases of matter. Such a formulation has recently been extended to higher electric multipole moments, through the discovery of the so ...

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3
Advanced Science, EarlyView.ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Quadrupole topological photonic crystals
Nature Communications, 2020 Most higher order topological phases are realized by emulations of tight binding models. Extending these concepts to continuum theories requires the identification of invariants describing the bulk multipole order.

Kinetic energy in the collective quadrupole Hamiltonian from the experimental data
Physics Letters B, 2017 Dependence of the kinetic energy term of the collective nuclear Hamiltonian on collective momentum is considered. It is shown that the fourth order in collective momentum term of the collective quadrupole Hamiltonian generates a sizable effect on the ...
