Topological charge and bulk-surface correspondence for quad-helicoid surface states in topological semimetals with two glide-time-reversal symmetries
Taiki Yukitake, Shuichi Murakami
Quad-helicoid surface states (QHSSs) are unique surface states with two pairs of helicoid surface states in topological semimetals such as Dirac semimetals. So far, topologically p…
Local expression of fractional corner charges in obstructed atomic insulators and relationship with the fractional disclination charges
Hidetoshi Wada, Shuichi Murakami
In obstructed atomic insulators, fractionally quantized charges appear at the corners of the crystals in the shapes of vertex-transitive polyhedra, and are given by the filling ano…
Hopper-Like Growth of Higher-Order Topological Insulators
Yutaro Tanaka, Shuai Zhang, Tiantian Zhang +1
Understanding crystal growth and morphology is a fundamental issue in condensed matter physics. While crystal morphology due to the distribution and dynamics of the diffusion field…
Unraveling a chemical-bond-driven root of topology in three-dimensional chiral crystals
Shungo Aoyagi, Shunsuke Kitou, Yuiga Nakamura +6
Chirality manifests across multiple scales, yielding unique phenomena that break mirror symmetry. In chiral materials, unexpectedly large spin-filtering or photogalvanic effects ha…
Advances in Phonons: From Band Topology to Phonon Chirality
Tiantian Zhang, Yizhou Liu, Hu Miao +1
Phonons, the quantized collective vibrations of a crystal lattice, are among the most fundamental bosonic excitations in condensed matter systems. They govern thermal transport, me…
Weyl Phonons: The connection of topology and chirality
Tiantian Zhang, Shuichi Murakami, Hu Miao
Topology and chirality of fermionic quasiparticles have enabled exciting discoveries, including quantum anomalous Hall liquids and topological superconductivity. Recently, topologi…
Double-helicoid surface states in Dirac semimetals protected by glide-time-reversal symmetry
Taiki Yukitake, Daisuke Hara, Shuichi Murakami
Recently, some monopole charges were defined for Dirac semimetals with symmetry (: glide, : time-reversal) in previous works, and the…
