Are There Universal Signatures of Topological Phases in High-Harmonic Generation? Probably Not. [PDF]
Physical Review X, 2023 High harmonic generation (HHG) has developed in recent years as a promising tool for ultrafast materials spectroscopy. At the forefront of these advancements, several works proposed using HHG as an all-optical probe for topology of quantum matter by ...

Discriminating different classes of biological networks by analyzing the graphs spectra distribution. [PDF]
PLoS ONE, 2012 The brain's structural and functional systems, protein-protein interaction, and gene networks are examples of biological systems that share some features of complex networks, such as highly connected nodes, modularity, and small-world topology.

Phase‐Space Generalized Brillouin Zone For Spatially Inhomogeneous Non‐Hermitian Systems
Advanced ScienceThe generalized Brillouin zone (GBZ) is highly successful in characterizing the topology and band structure of non‐Hermitian systems. However, its applicability ischallenged in spatially inhomogeneous settings, where the non‐locality of non‐Hermitian ...

Symmetry and topology of hyperbolic Haldane models [PDF]
Physical review B, 2023 Particles hopping on a two-dimensional hyperbolic lattice feature unconventional energy spectra and wave functions that provide a largely uncharted platform for topological phases of matter beyond the Euclidean paradigm.

Hierarchical Cyclic Pursuit: Algebraic Curves Containing the Laplacian Spectra [PDF]
IEEE Transactions on Control of Network Systems, 2022 This article addresses the problem of multiagent communication in networks with a regular directed ring structure. These can be viewed as hierarchical extensions of the classical cyclic pursuit topology.

Noncommutative CW-spectra as enriched presheaves on matrix algebras [PDF]
Journal of Noncommutative Geometry, 2021 Motivated by the philosophy that C∗-algebras reflect noncommutative topology, we investigate the stable homotopy theory of the (opposite) category of C∗-algebras. We focus on C∗-algebras which are non-commutative CW-complexes in the sense of [ELP].

Spectral recognition of graphs [PDF]
Yugoslav Journal of Operations Research, 2012 At some time, in the childhood of spectral graph theory, it was conjectured that non-isomorphic graphs have different spectra, i.e. that graphs are characterized by their spectra.

Insights into protein aggregation by NMR characterization of insoluble SH3 mutants solubilized in salt-free water. [PDF]
PLoS ONE, 2009 Protein aggregation in vivo has been extensively associated with a large spectrum of human diseases. On the other hand, mechanistic insights into protein aggregation in vitro were incomplete due to the inability in solubilizing insoluble proteins for ...

Bulk Entanglement and Boundary Spectra in Gapped Topological Phases [PDF]
, 2018 We study the correspondence between boundary spectrum of non-chiral topological orders on an open manifold $\mathcal{M}$ with gapped boundaries and the entanglement spectrum in the bulk of gapped topological orders on a closed manifold.

Transport theory in non-Hermitian systems [PDF]
Physical review B, 2023 Non-Hermitian systems have garnered significant attention due to the emergence of novel topology of complex spectra and skin modes. However, investigating transport phenomena in such systems faces obstacles stemming from the non-unitary nature of time ...
