Higher-winding phases in one-dimensional non-Hermitian topological superconductors
Yung-Yeh Chang, Xiang-Yu Li, Ken Shiozaki +1
Non-Hermitian topological superconductors provide a setting in which point-gap topology, non-Hermitian skin effects, and Majorana zero modes are strongly intertwined. In this work,…
Intrinsic non-Hermitian topological phases
Ken Shiozaki
We study the interplay of non-Hermitian topological phases under point- and line-gap conditions. Using natural homomorphisms from line-gap to point-gap phases, we distinguish extri…
-theory classification of Wannier localizability and detachable topological boundary states
Ken Shiozaki, Daichi Nakamura, Kenji Shimomura +2
A hallmark of certain topology, including the Chern number, is the obstruction to constructing exponentially localized Wannier functions in the bulk bands. Conversely, other types…
Non-Hermitian Origin of Detachable Boundary States in Topological Insulators
Daichi Nakamura, Ken Shiozaki, Kenji Shimomura +2
While topology can impose obstructions to exponentially localized Wannier functions, certain topological insulators are exempt from such Wannier obstructions. The absence of the Wa…
Nonsymmorphic Topological Phases of Non-Hermitian Systems
Daichi Nakamura, Yutaro Tanaka, Ken Shiozaki +1
Non-Hermiticity appears ubiquitously in various open classical and quantum systems and enriches classification of topological phases. However, the role of nonsymmorphic symmetry, c…
