Measuring chiral phonons
Rahul Rao, Hanyu Zhu, Nicholas Kotov +7
Chiral phonons are quantized vibrations where the atomic motion in a solid breaks improper rotation symmetries. In many cases, chiral phonons possess angular momenta and are theref…
Transport Enhancement and In Situ Control of Electronic Correlation via Photoinduced Modulation Doping of van der Waals Heterostructures
Collin R. Sanborn, Son T. Le, Thuc T. Mai +7
Modulation doping, a well-established technique for traditional semiconductor heterostructures, is a promising approach for tailoring carrier concentration in 2D materials devices.…
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,…
