Tunable and efficient ultraviolet generation in nanophotonic lithium niobate

Kavli Affiliate: Alireza Marandi | First 5 Authors: Emily Hwang, Nathan Harper, Ryoto Sekine, Luis Ledezma, Alireza Marandi | Summary: On-chip ultraviolet sources are of great interest for building compact and scalable atomic clocks, quantum computers, and spectrometers; however, few material platforms are suitable for integrated ultraviolet light generation. Of these materials, thin-film lithium niobate […]

SPT-CL J2215-3537: A Massive Starburst at the Center of the Most Distant Relaxed Galaxy Cluster

Kavli Affiliate: Adam Mantz | Summary:We present the discovery of the most distant, dynamically relaxed cool core cluster, SPT-CL J2215-3537 (SPT2215) and its central brightest cluster galaxy (BCG) at z=1.16. Using new X-ray observations, we demonstrate that SPT2215 harbors a strong cool core, with a central cooling time of 200 Myr (at 10 kpc) and […]

Anatomy of plasmons in generic Luttinger semimetals

Kavli Affiliate: Jing Wang | First 5 Authors: , , , , | Summary: We investigate the parameter regimes favourable for the emergence of plasmons in isotropic, anisotropic, and band-mass symmetric and asymmetric Luttinger semimetals (LSMs). An LSM harbours a quadratic band-crossing point (QBCP) in its bandstructure, where the upper and lower branches of dispersion […]
