Fermi Surface Spin Texture and Topological Superconductivity in Spin-Orbit Free Non-Collinear Antiferromagnets
Seung Hun Lee, Bohm-Jung Yang
We explore the relationship among the magnetic ordering in real space, the resulting spin texture on the Fermi surface, and the related superconducting gap structure in non-colline…
Quantum Geometry and Landau Levels of Quadratic Band Crossings
Junseo Jung, Hyeongmuk Lim, Bohm-Jung Yang
We study the relation between the quantum geometry of wave functions and the Landau level (LL) spectrum of two-band Hamiltonians with a quadratic band crossing point (QBCP) in two-…
Emergent dynamics of scale-free interactions in fractional quantum Hall fluids
Bo Yang
We show that even in the limit of large cyclotron gap, Landau level (LL) mixing can be dominant with scale-free interaction between charged ``elementary particles" in a fractional…
Quantum Valley and Sub-valley Hall Effect in the Large Angle Twisted Bilayer Graphene
Chiranjit Mondal, Rasoul Ghadimi, Bohm-Jung Yang
We study the quantum valley Hall effect and related domain wall modes in twisted bilayer graphene at a large commensurate angle. Due to the quantum valley and sub-valley Hall effec…
Real Hopf Insulator
Hyeongmuk Lim, Sunje Kim, Bohm-Jung Yang
Establishing the fundamental relation between the homotopy invariants and the band topology of Hamiltonians has played a critical role in the recent development of topological phas…
Boundary obstructed topological superconductor in buckled honeycomb lattice under perpendicular electric field
Rasoul Ghadimi, Seung Hun Lee, Bohm-Jung Yang
In this work, we show that a buckled honeycomb lattice can host a boundary-obstructed topological superconductor (BOTS) in the presence of f-wave spin-triplet pairing (fSTP). The u…
