Current-based RF charge sensing in a carbon nanotube
Marta Cagetti, Stefan Forstner, Victor Champain +8
The paper presents a current-mode charge sensor built from a suspended carbon nanotube that operates at a 1.25 MHz RLC resonance, achieving 0.15 µe/√Hz charge sensitivity and enabl…
Tunable nonlinear electromechanics at the zero-point motion scale
Christoffer B. Møller, Roger Tormo-Queralt, Elsa Vázquez-RodrÃguez +13
Nonlinearity at the scale of zero-point motion opens new possibilities for the control and readout of nanomechanical systems, but achieving this remains a formidable challenge. Her…
Imaging superconducting weak spots through vortex-assisted THz near-field photovoltage
Sergio J. SalvÃa-Fernández, Ekaterina Khestanova, Zoe Velluire-Pellat +9
Nanoscale inhomogeneities are a defining feature of many superconducting materials, yet their local electromagnetic response has remained difficult to access experimentally. This i…
X-ray Fractional Orbital Angular Momentum from Coherent Magnetic Scattering
P. D. Montgomery, J. S. Woods, M. R. McCarter +10
Artificial spin ice (ASI) based on a square lattice with a topological defect are known to generate orbital angular momentum (OAM) in diffracted X-ray beams. A previous investigati…
Silicon-on-sapphire metasurfaces generate arrays of dark and bright traps for neutral atoms
Chengyu Fang, Minjeong Kim, Hongyan Mei +10
We demonstrated crystalline silicon-on-sapphire (c-SOS) metasurfaces that convert a Gaussian beam into arrays of complex optical traps, including arrays of optical bottle beams tha…
A validated lumped-element model for bioinspired acoustic flow sensing toward the performance limit
Wei Sun, Wanyin Zheng, Xiangyu Wei +3
Flow sensing is fundamental to both biological survival and technological innovation. Inspired by biological mechanoreceptors, artificial flow sensors detect subtle fluid motion us…
