Quaternion-Kähler geometry of time reversal symmetric crystals
Hyeongmuk Lim, Junseo Jung, Yuting Qian +1
Quantum geometry reveals how the shape of Bloch wave functions governs correlated quantum phenomena. Its standard formulation describes isolated complex bands, where Berry curvatur…
Geometric Spin Degeneracy in Spin-Orbit-Free Compensated Magnets
Seung Hun Lee, Yuting Qian, Xi Dai +1
Compensated magnets with vanishing net magnetization can exhibit both pronounced spin splitting and unconventional band degeneracies. In altermagnets, such degeneracies are enforce…
Measurements of the quantum geometric tensor in solids
Mingu Kang, Sunje Kim, Yuting Qian +15
Understanding the geometric properties of quantum states and their implications in fundamental physical phenomena is at the core of modern physics. The Quantum Geometric Tensor (QG…
Euler band topology in spin-orbit coupled magnetic systems
Seung Hun Lee, Yuting Qian, Bohm-Jung Yang
The Euler class characterizes the topology of two real bands isolated from other bands in two-dimensions. Despite various intriguing topological properties predicted up to now, the…
Nodal fermions in a strongly spin-orbit coupled frustrated pyrochlore superconductor
Dongjin Oh, Junha Kang, Yuting Qian +11
The pyrochlore lattice, a three-dimensional network of corner-sharing tetrahedra, is a promising material playground for correlated topological phases arising from the interplay be…
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…
