Coexisting Euler and Stiefel-Whitney Topological Phases in Elastic Metamaterials
Jijie Tang, Adrien Bouhon, Yue Shen +6
The study of topological band theory in classical structures has led to the development of novel topological metamaterials with intriguing properties. While single-gap topologies a…
Photo-induced electronic and spin topological phase transitions in monolayer bismuth
Bo Peng, Gunnar F. Lange, Daniel Bennett +3
Ultrathin bismuth exhibits rich physics including strong spin-orbit coupling, ferroelectricity, nontrivial topology, and light-induced structural dynamics. We use \textit{ab initio…
High-chirality and multiquaternion Weyl nodes in hexagonal ReO
Siyu Chen, Robert-Jan Slager, Bartomeu Monserrat +1
The formation of two-band nodal points in gapless topological phases, referred to as conventional Weyl nodes, relies solely on translational symmetry. However, when coupled with ot…
Theory of polarization textures in crystal supercells
Daniel Bennett, Wojciech J. Jankowski, Gaurav Chaudhary +2
Recently, topologically nontrivial polarization textures have been predicted and observed in nanoscale systems. While these polarization textures are interesting and promising in t…
Polar meron-antimeron networks in strained and twisted bilayers
Daniel Bennett, Gaurav Chaudhary, Robert-Jan Slager +2
Out-of-plane polar domain structures have recently been discovered in strained and twisted bilayers of inversion symmetry broken systems such as hexagonal boron nitride. Here we sh…
Unconventional Surface State Pairs in a High-Symmetry Lattice with Anti-ferromagnetic Band-folding
L. -L. Wang, J. Ahn, R. -J. Slager +8
Many complex magnetic structures in a high-symmetry lattice can arise from a superposition of well-defined magnetic wave vectors. These "multi-q" structures have garnered much atte…
