On the Homotopy Coherent Nielsen Realization Problem for K3-Type 4-Manifolds
Yujie Lin, Yi Sha
We study the homotopy coherent analogue of the Nielsen realization problem for smooth 4-manifolds. Using family Seiberg-Witten theory, we prove that for K3-type 4-manifolds and the…

Surface density-of-states on semi-infinite topological photonic and acoustic crystals
Yi-Xin Sha, Bo-Yuan Liu, Hao-Zhe Gao +5
Iterative Green's function, based on cyclic reduction of block tridiagonal matrices, has been the ideal algorithm, through tight-binding models, to compute the surface density-of-s…

Discovering topological surface states of Dirac points
Hengbin Cheng, Yixin Sha, Rongjuan Liu +2
Dirac materials, unlike the Weyl materials, have not been found in experiments to support intrinsic topological surface states, as the surface arcs in existing systems are unstable…
