Surprisingly, the spin-valley locking in a two-dimensional superconductor with spin-orbit interaction makes the superconducting state resilient to large magnetic fields. We investigate the spectral properties of such an Ising superconductor in a magnetic field taking into account disorder. The interplay of the in-plane magnetic field and the Ising spin-orbit coupling leads to noncollinear effective fields. We find that the emerging singlet and triplet pairing correlations manifest themselves in the occurrence of "mirage" gaps: at (high) energies of the order of the spin-orbit coupling strength, a gap-like structure in the spectrum emerges that mirrors the main superconducting gap. We show that these mirage gaps are signatures of the equal-spin triplet finite-energy pairing correlations and due to their odd parity are sensitive to intervalley scattering.</dcterms:abstract> <dc:contributor>Belzig, Wolfgang</dc:contributor> <dc:language>eng</dc:language> <dcterms:isPartOf rdf:resource=""/> <bibo:uri rdf:resource=""/> <dc:contributor>Bruder, Christoph</dc:contributor> <dc:rights>terms-of-use</dc:rights> <dc:creator>Belzig, Wolfgang</dc:creator> <dc:contributor>Tang, Gaomin</dc:contributor> <dcterms:available rdf:datatype="">2020-11-19T16:17:57Z</dcterms:available> <dcterms:issued>2020-11-13T19:00:15Z</dcterms:issued> </rdf:Description> </rdf:RDF>
