A particularly interesting phenomenon is the emergence of mobility edges, which separate localized and extended states within the same energy spectrum. In strictly one-dimensional quasiperiodic systems described by the standard Aubry-Andr\u00e9 model, these mobility edges are conventionally absent due to an inherent global self-duality. This thesis investigates the localization properties in Aubry-Andr\u00e9 atomic wires, demonstrating that the simultaneous addition of spin-orbit coupling and transverse Rabi fields explicitly breaks this self-duality. The effects of the fermionic filling factor and the varying degrees of duality breaking are studied to build a comprehensive picture of how these fields generate robust mobility regions. Additionally, this thesis explores the topological properties of the system by treating the relative optical laser phase as a synthetic dimension, enabling an exact mapping to two-dimensional quantum Hall systems to classify three distinct topological phases.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EBreaking Duality: Mobility Regions and Topological Phases in Spin-Orbit Coupled Atomic Wires\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Breaking Duality: Mobility Regions and Topological Phases in Spin-Orbit Coupled Atomic Wires"}],"uid":"27707","created_gmt":"2026-04-07 20:55:42","changed_gmt":"2026-04-07 20:56:23","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-10T10:00:00-04:00","event_time_end":"2026-04-10T12:00:00-04:00","event_time_end_last":"2026-04-10T12:00:00-04:00","gmt_time_start":"2026-04-10 14:00:00","gmt_time_end":"2026-04-10 16:00:00","gmt_time_end_last":"2026-04-10 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Pettit Microelectronics, 102A\u0026B ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
