Quantum dynamical signatures of non-Hermitian boundary modes
Fan Yang, Maria Zelenayova, Paolo Molignini +1
The non-Hermitian bulk-boundary correspondence features an interplay between the non-Hermitian skin effect and anomalous boundary-mode behavior. Whereas the skin effect is known to…

Filling-Sensitive Spectral Complexity from Hilbert-Space Holonomy in Fragmented Non-Hermitian Systems
Jiong-Hao Wang, Maria Zelenayova, Christopher Ekman +1
We show that Hilbert-space holonomy provides a geometric organizing principle for spectral reality in fragmented non-Hermitian many-body systems, complementary to conventional symm…

Quantum Potts Models on the SierpiÅski Pyramid
Roman KrÄmár, Mária Zelenayová, Jozef Genzor +4
Phase transition of the two- and three-state quantum Potts models on the SierpiÅski pyramid are studied by means of a tensor network framework, the higher-order tensor renormaliza…
