Self-regulating surfaces for efficient liquid collection

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Christian Machado, Yuehan Yao, Emma Feldman, Joanna Aizenberg, Kyoo-Chul Kenneth Park | Summary: To achieve efficient liquid collection, a surface must regulate incoming liquid accumulation with outgoing liquid transport. Often, this can be proposed to be achieved by functionalizing surfaces with non-wetting characteristics. Yet, there remain fundamental, […]

Soliton generation in AlGaAs microresonators at room temperature

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Lue Wu, Weiqiang Xie, Chao Xiang, Lin Chang, Yan Yu | Summary: Chip-integrated optical frequency combs are attractive optical sources in comb applications requiring high-repetition-rate, low power consumption, or compact size. Spontaneous soliton formation via Kerr parametric oscillation is a promising generation principle in these frequency […]

Nonlinear waves at the free surface of flexible mechanical metamaterials

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Bolei Deng, Hang Shu, Jian Li, Chengyang Mo, Jordan R. Raney | Summary: In this letter we investigate the propagation of nonlinear pulses along the free surface of flexible metamaterials based on the rotating squares mechanism. While these metamaterials have previously been shown to support the propagation […]

Beating ringdowns of near-degenerate mechanical resonances

Kavli Affiliate: Simon Groblacher | First 5 Authors: Matthijs H. J. de Jong, Andrea Cupertino, Dongil Shin, Simon Gröblacher, Farbod Alijani | Summary: Mechanical resonators that possess coupled modes with harmonic frequency relations have recently sparked interest due to their suitability for controllable energy transfer and non-Hermitian dynamics. Here, we show coupling between high Q-factor […]

Electrostatic control of the proximity effect in the bulk of semiconductor-superconductor hybrids

Kavli Affiliate: L. P. Kouwenhoven | First 5 Authors: N. van Loo, G. P. Mazur, T. Dvir, G. Wang, R. C. Dekker | Summary: The proximity effect in semiconductor-superconductor nanowires is expected to generate an induced gap in the semiconductor. The magnitude of this induced gap, together with the semiconductor properties like the spin-orbit coupling […]
