Are There Universal Signatures of Topological Phases in High-Harmonic Generation? Probably Not.

open access: yesPhysical 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 ...

GENERALIZED THOM SPECTRA AND THEIR TOPOLOGICAL HOCHSCHILD HOMOLOGY [PDF]

open access: yesJournal of the Institute of Mathematics of Jussieu, 2017
We develop a theory of$R$-module Thom spectra for a commutative symmetric ring spectrum$R$and we analyze their multiplicative properties. As an interesting source of examples, we show that$R$-algebra Thom spectra associated to the special unitary groups can be described in terms of quotient constructions on$R$.

Spectral recognition of graphs [PDF]

open access: yesYugoslav 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]

open access: yesPLoS 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 ...

Joint Spectra of Generators in Topological Algebras [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
Let𝒜be a complex topological algebra with unit 1 and𝒰a family of proper closed ideals in𝒜. For an arbitraryS⊂𝒜we define a globally defined joint spectrumσ𝒰(S)={(λs)s∈S∈ℂS  |  ∃ I  ∈𝒰(s−λs)∈I ∀s∈S}. We prove that forSgenerating𝒜the spectrumσ𝒰(S)can be identified with the set𝔐𝒰of continuous multiplicative functionalsfon𝒜such that kerf∈𝒰.

Geometrical description and Faddeev-Jackiw quantization of electrical networks [PDF]

open access: yesQuantum
In lumped-element electrical circuit theory, the problem of solving Maxwell's equations in the presence of media is reduced to two sets of equations, the constitutive equations encapsulating local geometry and dynamics of a confined energy density, and ...

Discriminating different classes of biological networks by analyzing the graphs spectra distribution.

open access: yesPLoS 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.

PROBLEM OF SUPER-STRONG MAGNETIC FIELDS ON THE SUN: BRIEF CHRONOLOGY AND NEW OBSERVATIONAL DATA

open access: yesOdessa Astronomical Publications, 2018
In this study we present the old and new observational data concerning the problem of extreme magnetic fields (  5 kG) in the Sun's atmosphere. We emphasize that the upper limit of the intensity of the magnetic field in the solar atmosphere is unknown ...

On the generalized spectra of topological algebras

open access: yesJournal of Mathematical Analysis and Applications, 1973
Local equicontinuity of the generalized spectra of certain topological algebras implies that the spectra in question coincide as topological spaces with the generalized spectra of the respective completed topological algebras [7]. On the other hand, for a fairly large class of topological algebras (i.e., m-barreled locally convex algebras), local ...
