Ultraviolet Exciton-Polaritons in Silver Phenylthiolate
Bongjun Choi, Bonnie Chen, Thuc T. Mai +8
Ultraviolet (UV) exciton-polaritons (EPs) enable nonlinear optics, polaritonic lasing, and polariton-mediated photochemistry in the short-wavelength regime, yet progress has been l…
Raman and Terahertz Spectroscopy of Low-Frequency Chiral Phonons in Amino Acids
Rahul Rao, Won Jin Choi, Joseph M. Slocik +6
Chiral phonons are mirror-symmetric vibrations that correspond to twisting and rotational motions of atoms. In chiral biomolecules, they correspond to low-energy terahertz (THz)-ra…
Coupled Ferroelectricity and Phonon Chirality
Xiang-Bin Han, Cong Yang, Rui Sun +10
The ability to control chirality and chiral phonons offers a route to manipulate the direction of spin and angular-momentum transport. In materials with rigid structural chirality,…
Weyl Magnons in the Non-Coplanar Antiferromagnet MnTe
Ahmed E. Fahmy, Archibald J. Williams, Yufei Li +9
Using a combination of band representation analysis, inelastic neutron scattering (INS), magneto-Raman spectroscopy measurements, and linear spin wave theory, we establish that the…
Strong Raman Optical Activity and Chiral Phonons in Chiral Hybrid Organic-Inorganic Perovskites
Evan W. Muller, Aleksey Ruditskiy, Jie Jiang +6
Hybrid organic-inorganic perovskites with chiral organic cations are very interesting for optoelectronic applications because of their intrinsically chiral light-matter interaction…
Spin-lattice entanglement in
Thuc T. Mai, Amber McCreary, K. F. Garrity +12
Complex chalcogenides in the PS family of materials ( = Mn, Fe, Co, and Ni) display remarkably different phase progressions depending upon the metal center orbital fillin…
