Published in 2017 at "Communications in Mathematical Physics"

DOI: 10.1007/s00220-017-3015-6

Abstract: We disprove a conjecture of Breuer–Last–Simon (Breuer et al. in Constr Approx 32(2):221–254, 2010) concerning the absolutely continuous spectrum of Jacobi matrices with coefficients that obey an ℓ2 bounded variation condition with step q. We prove… read more here.

Published in 2018 at "Journal of Mathematical Analysis and Applications"

DOI: 10.1016/j.jmaa.2018.06.056

Abstract: We establish concrete criteria for fully supported absolutely continuous spectrum for ergodic CMV matrices and purely absolutely continuous spectrum for limit-periodic CMV matrices. We proceed by proving several variational estimates on the measure of the… read more here.

Published in 2023 at "Journal of Cosmology and Astroparticle Physics"

DOI: 10.1088/1475-7516/2023/04/002

Abstract: We study the effects of a massive field with a continuous spectrum (continuum isocurvaton) on the inflationary bispectrum in the squeezed limit. As a concrete example, we extend the quasi-single field inflation model to include… read more here.

Published in 2022 at "IEEE Systems Journal"

DOI: 10.1109/jsyst.2021.3116273

Abstract: Through interacting with wireless environments continuously, continuous spectrum sensing (CSS) had been proposed in the literature to alleviate problems introduced by quiet periods in cognitive radio systems. However, in conventional bandwidth-fixed CSS (BF-CSS) schemes, the… read more here.

Published in 2022 at "Optics letters"

DOI: 10.1364/ol.448477

Abstract: A spectral method for determining the stability of periodically stationary pulses in fiber lasers is introduced. Pulse stability is characterized in terms of the spectrum (eigenvalues) of the monodromy operator, which is the linearization of… read more here.

Published in 2021 at "Atoms"

DOI: 10.3390/atoms9030055

Abstract: We consider the redistribution of the Rydberg state population resulting from multistep cascade transitions induced by radiation with a continuous spectrum. The population distribution is analyzed within the space of quantum numbers n and l.… read more here.
