Multifractal Analysis of the Non-Hermitian Skin Effect: From Many-Body to Tree Models

Shu Hamanaka

The non-Hermitian skin effect is an anomalous localization phenomenon induced by nonreciprocal dissipation and has attracted considerable attention in recent years both theoretical…

Koopman Nonlinear Non-Hermitian Skin Effect

Shu Hamanaka

Non-Hermitian skin effects are conventionally manifested as boundary localization of eigenstates in linear systems. In nonlinear settings, however, where eigenstates are no longer…

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-…

Callan-Rubakov effects in topological insulators

Yusuke O. Nakai, Reuel Dsouza, Daichi Nakamura +3

The Callan-Rubakov effect describes monopole-catalyzed proton decay. While this effect is fundamental for quantum field theories, its experimental observation has remained far from…

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…

Multifractality of many-body non-Hermitian skin effect

Shu Hamanaka, Kohei Kawabata

The non-Hermitian skin effect, anomalous localization of an extensive number of eigenstates induced by nonreciprocal dissipation, plays a pivotal role in non-Hermitian topology and…

Interaction-induced Liouvillian skin effect in a fermionic chain with a two-body loss

Shu Hamanaka, Kazuki Yamamoto, Tsuneya Yoshida

Despite recent intensive research on topological aspects of open quantum systems, effects of strong interactions have not been sufficiently explored. In this paper, we demonstrate…
