Due to a breaking of the C4 symmetry, the coexisting phase inherently contains admixture of the s-wave pairing components. As a result, the superconducting gap exhibits nonstandard features including changed nodal directions. Our results also show that in the optimally doped regime the pure superconducting phase is typically unstable towards developing nematicity (breaking of the C4 symmetry). This has implications for the cuprate high-Tc superconductors, for which in this regime the so-called intertwined orders have recently been observed. Namely, the coexisting phase may be viewed as a precursor to such more involved patterns of symmetry breaking."}],"main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1512.06688"}],"department":[{"_id":"MiLe"}],"issue":"8","publication_status":"published","date_published":"2016-08-30T00:00:00Z","date_updated":"2021-01-12T06:50:05Z","month":"08","day":"30","type":"journal_article","project":[{"grant_number":"291734","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"acknowledgement":"The authors are grateful to Florian Gebhard and Mikhail Lemeshko for discussions and critical reading of the manuscript.
