In this context, the robust valley degree of freedom and the associated valley pseudospin found in two-dimensional transition metal dichalcogenides is a highly attractive platform. Valley polarization and coherent superposition of valley states have been observed in these systems even up to room temperature. Control of valley coherence is an important building block for the implementation of valley qubit. Large magnetic fields or high-power lasers have been used in the past to demonstrate the control (initialization and rotation) of the valley coherent states. Here, the control of layer–valley coherence via strong coupling of valley excitons in bilayer WS2 to microcavity photons is demonstrated by exploiting the pseudomagnetic field arising in optical cavities owing to the transverse electric–transverse magnetic (TE–TM)mode splitting. The use of photonic structures to generate pseudomagnetic fields which can be used to manipulate exciton-polaritons presents an attractive approach to control optical responses without the need for large magnets or high-intensity optical pump powers."}],"intvolume":"        11","publication_identifier":{"eissn":["2195-1071"]},"type":"journal_article","author":[{"last_name":"Khatoniar","first_name":"Mandeep","full_name":"Khatoniar, Mandeep"},{"last_name":"Yama","first_name":"Nicholas","full_name":"Yama, Nicholas"},{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","first_name":"Areg","orcid":"0000-0001-9666-3543","full_name":"Ghazaryan, Areg"},{"full_name":"Guddala, Sriram","first_name":"Sriram","last_name":"Guddala"},{"first_name":"Pouyan","last_name":"Ghaemi","full_name":"Ghaemi, Pouyan"},{"first_name":"Kausik","last_name":"Majumdar","full_name":"Majumdar, Kausik"},{"full_name":"Menon, Vinod","last_name":"Menon","first_name":"Vinod"}],"quality_controlled":"1","publication_status":"published","date_published":"2023-07-04T00:00:00Z","date_updated":"2023-10-04T11:15:17Z","volume":11,"scopus_import":"1","article_type":"original","year":"2023","status":"public","oa_version":"Preprint","publication":"Advanced Optical Materials","external_id":{"isi":["000963866700001"],"arxiv":["2211.08755"]},"issue":"13","department":[{"_id":"MiLe"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Optical manipulation of Layer–Valley coherence via strong exciton–photon coupling in microcavities","month":"07","citation":{"mla":"Khatoniar, Mandeep, et al. “Optical Manipulation of Layer–Valley Coherence via Strong Exciton–Photon Coupling in Microcavities.” <i>Advanced Optical Materials</i>, vol. 11, no. 13, 2202631, Wiley, 2023, doi:<a href=\"https://doi.org/10.1002/adom.202202631\">10.1002/adom.202202631</a>.","apa":"Khatoniar, M., Yama, N., Ghazaryan, A., Guddala, S., Ghaemi, P., Majumdar, K., &#38; Menon, V.
