Room-temperature valley-selective emission in Si-MoSe2 heterostructures enabled by high-quality-factor chiroptical cavities
Feng Pan, Xin Li, Amalya C. Johnson +14
Transition metal dichalcogenides possess valley pseudospin, enabling coupling between photon spin and electron spin for classical and quantum information processing. However, rapid…
Macroscopic uniform 2D moiré superlattices with controllable angles
Gregory Zaborski, Paulina E. Majchrzak, Samuel Lai +8
Moiré superlattices, engineered through precise stacking of van der Waals (vdW) layers, hold immense promise for exploring strongly correlated and topological phenomena. However, t…
Direct Exfoliation of Nanoribbons from Bulk van der Waals Crystals
Ashley P. Saunders, Victoria Chen, Jierong Wang +8
Confinement of monolayers into quasi-one-dimensional atomically-thin nanoribbons could lead to novel quantum phenomena beyond those achieved in their bulk and monolayer counterpart…
Giant room-temperature nonlinearities from a monolayer Janus topological semiconductor
Jiaojian Shi, Haowei Xu, Christian Heide +16
Nonlinear optical materials possess wide applications, ranging from terahertz and mid-infrared detection to energy harvesting. Recently, the correlations between nonlinear optical…
Anti-Stokes Photoluminescence in Monolayer WSe Activated by Plasmonic Cavities through Resonant Excitation of Dark Excitons
Niclas S. Mueller, Rakesh Arul, Ashley P. Saunders +9
Anti-Stokes photoluminescence (PL) is light emission at a higher photon energy than the excitation, with applications in optical cooling, bioimaging, lasing, and quantum optics. He…
High-harmonic generation from artificially stacked 2D crystals
Christian Heide, Yuki Kobayashi, Amalya C. Johnson +4
We report a coherent layer-by-layer high-order harmonic generation (HHG) build-up in artificially stacked transition metal dichalcogenides (TMDC) crystals in their various stacking…
Achiral dielectric metasurfaces for spectral and polarization control of valley specific light emission from monolayer MoS2
Yin Liu, Sze Cheung Lau, Wen-Hui Sophia Cheng +9
Excitons in two-dimensional transition metal dichalcogenides have a valley degree of freedom that can be optically accessed and manipulated for quantum information processing. Here…
Floquet engineering of strongly-driven excitons in monolayer tungsten disulfide
Yuki Kobayashi, Christian Heide, Amalya C. Johnson +4
Interactions of quantum materials with strong-laser fields can induce exotic nonequilibrium electronic states. Monolayer transition-metal dichalcogenides, a new class of direct-gap…
Probing Electron-Hole Coherence in Strongly-Driven Solids
Christian Heide, Yuki Kobayashi, Amalya Johnson +4
High-harmonic generation (HHG) is a coherent optical process in which the incident photon energy is up-converted to the multiples of its initial energy. In solids, under the influe…
The Gas Content and Stripping of Local Group Dwarf Galaxies
Mary E. Putman, Yong Zheng, Adrian M. Price-Whelan +4
The gas content of the complete compilation of Local Group dwarf galaxies (119 within 2 Mpc) is presented using HI survey data. Within the virial radius of the Milky Way (224 kpc h…
The X-Ray Cavity Around Hotspot E in Cygnus A: Tunneled by a Deflected Jet
Bradford Snios, Amalya C. Johnson, Paul E. J. Nulsen +5
The powerful FR II radio galaxy Cygnus A exhibits primary and secondary hotspots in each lobe. A 2 Msec Chandra X-ray image of Cygnus A has revealed an approximately circular hole,…
