Global well-posedness and scattering for defocusing energy-critical inhomogeneous NLS in dimensions
Bo Yang, Lei Zhang, Bin Liu
We study the defocusing energy-critical inhomogeneous nonlinear Schrödinger equation \[ i\partial_tu+Δu=|x|^{-b}|u|^{\frac{4-2b}{d-2}}u, \qquad (t,x)\in\R\times\R^d, \] with initia…
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…
Unconventional topological phase transition of the Hopf insulator
Sunje Kim, Ysun Choi, Hyeongmuk Lim +1
The topological phase transition between two band insulators is mediated by a gapless state whose low-energy band structure normally contains sufficient information for describing…
Quantum geometric bound and ideal condition for Euler band topology
Soonhyun Kwon, Bohm-Jung Yang
Understanding the relationship between quantum geometry and topological invariants is a central problem in the study of topological states. In this work, we establish the relations…
Topological protection of bound states against the hybridization
Bohm-Jung Yang, Mohammad Saeed Bahramy, Naoto Nagaosa
Topological invariants are conventionally known to be responsible for protection of extended states against disorder. A prominent example is the presence of topologically protected…
