Aggregation-engineered loss-tolerant strong coupling in metallic microcavities
Andrea Betti, Eleonora Cara, Giulia Serrano +7
Room-temperature strong coupling in organic microcavities is usually achieved by combining high-quality optical resonators with highly ordered excitonic media, a requirement that l…

Spin waves excited by hard x-ray transient gratings
Peter R. Miedaner, Alexei A. Maznev, Mykola Biednov +49
Recent progress in ultrafast x-ray sources helped establish x-rays as an important tool for probing lattice and magnetic dynamics initiated by femtosecond optical pulses. Here, we…

BGO relaxation dynamics probed with heterodyne detected optical transient gratings
Danny Fainozzi, Sara Catalini, Renato torre +2
We used optical laser pulses to create transient gratings (TGs) with sub-10 μm spatial periodicity in a Bismuth Germanate (310) (Bi4Ge3O12) single crystal at room temperature. The…
