Up to now, the existence conditions\u0000of this state rely on the presence of a double well in the KH potential,\u0000obtained by averaging the motion over one period of the laser. However, the\u0000approximation involved in the averaging is largely invalid in the region of the\u0000double well structure; therefore this raises the question of its relevance for\u0000identifying signatures of these exotic states. Here we present a method to\u0000establish conditions for the existence of the KH atom based on a\u0000nonperturbative approach. We show that the KH atom is structured by an\u0000asymmetric periodic orbit with the same period as the laser field in a wide\u0000range of laser parameters. Its imprint is clearly visible on the wavefunction\u0000in quantum simulations. We identify the range of parameters for which this KH\u0000state is effective, corresponding to an elliptic periodic orbit.","PeriodicalId":501039,"journal":{"name":"arXiv - PHYS - Atomic Physics","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141863790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
