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 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…
Non-Hermitian extended midgap states and bound states in the continuum
Maria Zelenayova, Emil J. Bergholtz
We investigate anomalous localization phenomena in non-Hermitian systems by solving a class of generalized Su-Schrieffer-Heeger/Rice-Mele models and by relating their provenance to…
Probing fractional statistics in quantum simulators of spin liquid Hamiltonians
Shiyu Zhou, Maria Zelenayova, Oliver Hart +2
Recent advances in programmable quantum devices brought to the fore the intriguing possibility of using them to realise and investigate topological quantum spin liquid phases. This…
Quantum Potts Models on the Sierpiński Pyramid
Roman Krčmár, Mária Zelenayová, Jozef Genzor +4
Phase transition of the two- and three-state quantum Potts models on the Sierpiński pyramid are studied by means of a tensor network framework, the higher-order tensor renormalizat…
