Topological Chiral Superconductivity Driven by Strong Repulsive Interactions in Fermi-Liquid Systems
Strong repulsive interactions can drive the formation of topological chiral superconductivity, which breaks time-reversal and reflection symmetries in the orbital motion of electrons, without relying on pairing instability in Fermi-liquids.
強磁場中のペアリングフェルミオンと偶数分母量子ホール階層の娘状態
強磁場中のペアリングフェルミオンは、偶数分母量子ホール階層の娘状態を生み出す。これらの娘状態は、弱く相互作用するコンポジット・フェルミオンの描像で統一的に理解できる。各娘状態は、コンポジット・フェルミオンのペアが形成する整数量子ホール状態である。ペアリングの種類によって、追加のコンポジット・フェルミオンのランダウ準位が決まる。
Unified Description of Daughter States Flanking Even-Denominator Quantum Hall Plateaus
Paired fermions in strong magnetic fields can form bosonic integer quantum Hall states, which correspond to the experimentally observed 'daughter states' flanking even-denominator quantum Hall plateaus.
Anisotropic Planar Hall Effect in Bi2Se3/EuS Interfaces: Interplay of Proximity-Induced Spin Canting and Topological Spin Texture
The planar Hall conductivity in Bi2Se3/EuS interfaces exhibits distinct anisotropic features depending on the orientation and magnitude of the proximity-induced magnetic moment in EuS, as well as the presence of a topological spin texture such as magnetic skyrmions.

The study demonstrates that both Cr1/3NbS2 and Mn1/3NbS2 exhibit chiral helical magnetism, with detailed characterization of the magnetic phases using nuclear magnetic resonance techniques.
NbTe2에서 전하밀도파와 공존하는 초전도성의 향상
NbTe2 초전도체의 임계온도가 0.56 K에서 2.8 K로 크게 향상되었으며, 이는 결정 구조의 1% 정도 팽창에도 불구하고 전하밀도파 질서가 여전히 공존하는 독특한 메커니즘에 의한 것으로 보인다.

The superconducting transition temperature (Tc) of NbTe2 is significantly enhanced from 0.56 K to 2.8 K, while the charge density wave (CDW) order still coexists in the lattice-expanded sample.
準結晶における無ギャップ超伝導とその実空間トポロジー
準結晶のアマン-ビーンカー型において、磁場下で無ギャップ超伝導が実現される。この無ギャップ超伝導は、準結晶特有の局在状態と並進対称性の破れに起因する。スピン軌道相互作用の存在下では、この無ギャップ超伝導相がトポロジカルに非自明となり、ゼロ近傍のエッジ状態が出現する。
Gapless Superconductivity and Topological Phases in Ammann-Beenker Quasicrystals
Ammann-Beenker quasicrystals can host gapless superconductivity under magnetic field, originating from the interplay of broken translational symmetry and highly degenerate confined states. The gapless superconducting phase can also be topologically nontrivial when Rashba spin-orbit coupling is present.
