Topological characterization of multifold band degeneracies in Altland-Zirnbauer symmetry classes

Askar Iliasov, Zoltán Guba, Tsuneya Yoshida +2

Topological degeneracies of energy bands in crystalline matter are conventionally characterized by invariants computed on an enclosing sphere over which the spectrum remains gapped…

Interacting Electronic Topology of Nonlocal Crystals

Shu Hamanaka, Martina O. Soldini, Tsuneya Yoshida +1

Nonlocal crystals are systems with translational symmetry but arbitrary-range couplings or interactions between degrees of freedom. We argue that such systems can realize symmetry-…

Hopf Exceptional Points

Tsuneya Yoshida, Emil J. Bergholtz, Tomáš Bzdušek

Exceptional points at which eigenvalues and eigenvectors of non-Hermitian matrices coalesce are ubiquitous in the description of a wide range of platforms from photonic or mechanic…

Winding Topology of Multifold Exceptional Points

Tsuneya Yoshida, J. Lukas K. König, Lukas Rødland +2

Despite their ubiquity, a systematic classification of multifold exceptional points, -fold spectral degeneracies (EPs), remains a significant unsolved problem. In this articl…

Multifractal statistics of non-Hermitian skin effect on the Cayley tree

Shu Hamanaka, Askar A. Iliasov, Titus Neupert +2

Multifractal analysis is a powerful tool for characterizing the localization properties of wave functions. Despite its utility, this tool has been predominantly applied to disorder…

Non-Hermitian Topology in Hermitian Topological Matter

Shu Hamanaka, Tsuneya Yoshida, Kohei Kawabata

Non-Hermiticity gives rise to distinctive topological phenomena absent in Hermitian systems. However, connection between such intrinsic non-Hermitian topology and Hermitian topolog…
