Majorana-assisted nonlocal spin correlation in quasi-one-dimensional Kitaev spin liquids
Yuki Yamazaki, Shingo Kobayashi, Akira Furusaki
We propose Majorana-assisted nonlocal spin correlation as a manifestation of Majorana nonlocality in quasi-one-dimensional (1D) Kitaev spin liquids. Focusing on the flux-free secto…
Hinge modes of three-dimensional Euler insulators
Yutaro Tanaka, Shingo Kobayashi
In two-dimensional systems with space-time inversion symmetry, such as , the reality condition on wave functions gives rise to real band topology characterized by the Eule…
Euler band topology in superfluids and superconductors
Shingo Kobayashi, Manabu Sato, Akira Furusaki
Real band topology often appears in systems with space-time inversion symmetry and is characterized by invariants such as the Euler and second Stiefel-Whitney classes. Here, we exa…
Three-dimensional spinless Euler insulators with rotational symmetry
Manabu Sato, Shingo Kobayashi, Motoaki Hirayama +1
The Euler class is a -valued topological invariant that characterizes a pair of real bands in a two-dimensional Brillouin zone. One of the symmetries that permits its d…
Higher-order topological phases for time-reversal-symmetry breaking superconductivity in UTe
Yuki Yamazaki, Shingo Kobayashi
The recent discovery of heavy-fermion superconductor UTe has broadened the possibility of realizing exotic time-reversal-symmetry-breaking superconductivity. However, a compreh…
Majorana multipole response with magnetic point group symmetry
Yuki Yamazaki, Shingo Kobayashi
Majorana fermions (MFs) in a topological superconductor exhibit anisotropic electromagnetic responses, called Majorana multipole responses, when MFs are degenerate under time-rever…
Representation-protected topology of spin-singlet -wave superconductors
Shingo Kobayashi, Akira Furusaki
We show that spin-singlet -wave multi-band superconductors have a topological phase protected by rotation symmetry and time-reversal symmetry without spin-orbit coupling in two…
Oscillating-charged Andreev Bound States and Their Appearance in UTe
Satoshi Ando, Shingo Kobayashi, Andreas P. Schnyder +2
Surface Andreev bound states, including Majorana bound states in topological superconductors, are typically charge neutral. In this work, we demonstrate the emergence of unconventi…
Ideal Spin-Orbit-Free Dirac Semimetal and Diverse Topological Transitions in PrCoGa Family
Manabu Sato, Juba Bouaziz, Shuntaro Sumita +5
Topological semimetals, known for their intriguing properties arising from band degeneracies, have garnered significant attention. However, the discovery of a material realization…
