摘要: 建立一維分?jǐn)?shù)階PT對(duì)稱(parity-time symmetry)對(duì)數(shù)非線性系統(tǒng)的理論模型,數(shù)值分析在不同的參數(shù)條件下一維分?jǐn)?shù)階PT對(duì)稱對(duì)數(shù)非線性系統(tǒng)中孤子的存在、穩(wěn)定性和傳輸演化特性。結(jié)果表明,當(dāng)分?jǐn)?shù)階效應(yīng)萊維指數(shù)保持不變時(shí),隨著傳播常數(shù)增大,孤子功率增加且具有良好的對(duì)稱性,而非線性效應(yīng)變強(qiáng),孤子穩(wěn)定區(qū)域變大并且在傳輸過程中穩(wěn)定性變差;當(dāng)分?jǐn)?shù)階效應(yīng)萊維指數(shù)增加時(shí),隨著傳播常數(shù)...
