A. Marjatta Lyyra is a Finnish and American physicist whose research has involved the development of triple-resonance nuclear magnetic resonance spectroscopy and its applications in molecular quantum optics, [1] including electromagnetically induced transparency. [2] She is a professor of physics at Temple University. [1]
Lyyra grew up in Finland in a family with five brothers. Deterred by allergy from a childhood interest in veterinary science, she turned to her second-favorite discipline, physics. [2] She became a student at the University of Helsinki in Finland, where she received a bachelor's degree in 1971 and a master's degree in 1973. [1]
She completed her Ph.D. at Stockholm University in Sweden in 1979, [1] also earning a license for deep-sea sailing in her time in Sweden. [2] Her doctoral dissertation, Molecular spectroscopy, was supervised by Philip Bunker. [3]
She worked as a research scientist at the University of Iowa, [4] where she helped pioneer triple-resonance spectroscopy with William Stwalley and Paul Kleiber, [1] before joining the Temple University faculty. [4]
Lyyra was elected as a Fellow of the American Physical Society (APS) in 2005, after a nomination from the APS Division of Laser Science, "for the development of multi-resonance laser spectroscopic technique for facilitating large inter-nuclear distance molecular excitation with state selectivity and for probing coherence effects in molecular systems". [5] In 2019, Optica named her as a fellow, "for significant contributions and leadership in experimental research in all-optical triple resonance spectroscopy and its application to frequency domain control of quantum state singlet/triplet character and all-optical spin switching".
