Scanning NV microscopy is used to image magnetic domains and switching in Mn\u2083Sn, resolve stacking-dependent magnetic phases in twisted CrI\u2083, and probe coherent microwave fields, magnetic noise, and vortices in a superconducting Nb resonator. The technique is further applied to twisted Bi\u2082Sr\u2082CaCu\u2082O\u2088+x, where local magnetic and noise measurements reveal boundary- and field-dependent responses associated with unconventional superconductivity. Together, these studies demonstrate scanning NV microscopy as a versatile multimodal platform for connecting nanoscale electromagnetic signals with microscopic phenomena in quantum materials.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EMultimodal Scanning-Probe Quantum Sensing of Quantum Materials\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Multimodal Scanning-Probe Quantum Sensing of Quantum Materials"}],"uid":"27707","created_gmt":"2026-09-21 16:35:22","changed_gmt":"2026-09-21 16:35:55","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-10-02T10:00:00-04:00","event_time_end":"2026-10-02T12:00:00-04:00","event_time_end_last":"2026-10-02T12:00:00-04:00","gmt_time_start":"2026-10-02 14:00:00","gmt_time_end":"2026-10-02 16:00:00","gmt_time_end_last":"2026-10-02 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Howey N210","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":""}}}
