Quantum materials QED with van der Waals crystals
Suheng Xu, Brian Vermilyea, Ran Jing +19
A central goal of the emerging field of materials QED is to harness subwavelength electromagnetic confinement in engineered cavities to tailor light-matter interactions. Here, we d…
Scaling native entanglement generation in layered semiconductors with quasi-phase matching
Benjamin Braun, Andrea Alessandrini, Josip Bajo +10
Efficient generation of entangled photons typically relies on spontaneous parametric down-conversion (SPDC) in phase-matched macroscopic nonlinear media. However, generating entang…
Plasmon dynamics in graphene
Suheng Xu, Birui Yang, Nishchhal Verma +15
Plasmon are collective oscillations of mobile electrons with dynamics controlled by their charge stiffness("Drude weight"). Using terahertz spacetime metrology, we probe Plasmon dy…
Space-time duality in polariton dynamics
Suheng Xu, Seunghwi Kim, Rocco A. Vitalone +13
The spatial and temporal dynamics of wave propagation are intertwined. A common manifestation of this duality emerges in the spatial and temporal decay of waves as they propagate t…
Quasi-phase-matched up- and down-conversion in periodically poled layered semiconductors
Chiara Trovatello, Carino Ferrante, Birui Yang +15
Nonlinear optics lies at the heart of classical and quantum light generation. The invention of periodic poling revolutionized nonlinear optics and its commercial applications by en…
Visualizing moiré ferroelectricity via plasmons and nano-photocurrent in graphene/twisted-WSe2 structures
Shuai Zhang, Yang Liu, Zhiyuan Sun +28
Ferroelectricity, a spontaneous and reversible electric polarization, is found in certain classes of van der Waals (vdW) material heterostructures. The discovery of ferroelectricit…
