(author), van der Zant, H.S.J. (author), Steeneken, P.G. (author)Magnetostrictive coupling has recently attracted interest as a sensitive method for studying magnetism in two-dimensional (2D) materials by mechanical means. However, its application in high-frequency magnetic actuators and transducers requires rapid modulation of the magnetic order, which is difficult to achieve with external magnets,...journal article 2023

Liu, Hanqing (author), Lee, M. (author), Siskins, M. (author), van der Zant, H.S.J. (author), Steeneken, P.G. (author), Verbiest, G.J. (author)Heat transport by acoustic phonons in two-dimensional (2D) materials is fundamentally different from that in 3D crystals because the out-of-plane phonons propagate in a unique way that strongly depends on tension and bending rigidity. Here, using optomechanical techniques, we experimentally demonstrate that the heat transport time in...journal article 2023

(author), Ruessink, Gerben (author)We investigate pathways of sediment diffusion for a Gaussian-shaped sand mound subjected to monochromatic waves. Our unique results nearly close the sediment budget by quantifying each of the sediment transport processes responsible for mound diffusion associated with sediment flux due to slope driven transport and ripple migration. Downslope...journal article 2023

Park, S.Y. (author), Newton, C.E.L. (author), Lee, Rachel (author)The sudden adoption of working from home (WFH) during the COVID-19 pandemic has required the reconfiguration of home spaces to fit space for remote work into existing spaces already filled with other domestic functions. This resulted in blurring of home and work boundaries, the potential lack of space for telecommuting from home, and...journal article 2023
