Exceptional degeneracies in non-Hermitian Rashba semiconductors [PDF]
, 2023 Exceptional points (EPs) are spectral degeneracies of non-Hermitian (NH) systems where eigenvalues and eigenvectors coalesce, inducing unique topological phases that have no counterpart in the Hermitian realm.

Two-photon driven Kerr quantum oscillator with multiple spectral degeneracies [PDF]
, 2023 Kerr nonlinear oscillators driven by a two-photon process are promising systems to encode quantum information and to ensure a hardware-efficient scaling towards fault-tolerant quantum computation.

Protection of all nondefective twofold degeneracies by antiunitary symmetries in non-Hermitian systems [PDF]
, 2022 Non-Hermitian degeneracies are classified as defective exceptional points (EPs) and nondefective de- generacies. While in defective EPs, both eigenvalues and eigenvectors coalesce, nondefective degeneracies are characterized merely by the emergence of ...

Probing many-body systems near spectral degeneracies [PDF]
, 2021 The diagonal elements of the time correlation matrix are used to probe closed quantum systems that are measured at random times. This enables us to extract two distinct parts of the quantum evolution, a recurrent part and an exponentially decaying part ...

Symbolic treatment of geometric degeneracies [PDF]
, 1990 Many descriptions of algorithms in computational geometry exclude degeneracies by fiat. Practitioners are left to their own devices for dealing with degeneracies when implementing such algorithms.

Degeneracies in molecular graph spectra [PDF]
, 1993 Unusual degeneracies of the Hü ckel π-molecular orbitals in some molecular frameworks is explained on the basis of the molecular graph decomposition. Unusual degeneracies in the eigen value spectrum of systems like 1 and 2 are explained on the basis of ...

The optical singularities of birefringent dichroic chiral crystals [PDF]
, 2003 Using a new formalism involving projection from the sphere of directions to the stereographic plane, and associated complex variables, explicit formulae are obtained for the two refractive indices and polarizations in optically anisotropic crystals that ...
