Visualization of Single Spin-chain Propagation using Bragg Coherent Diffraction Imaging
Xiaoqian M. Chen, Justin S. Woods, Ulrich Welp +11
Domain wall dynamics and their manipulation in finite-size systems serve as a promising platform for beyond Moore's law applications. Yet, the imaging techniques to track their mot…
A Si-on-SiC Platform for Interfacing with Vanadium Dopants in the Telecom O-Band
Timothy Draher, Nolan Bitner, Vasileios Niaouris +6
Vanadium color centers in silicon carbide (SiC) offer telecom O-band emission, sub-microsecond optical lifetimes, and second-scale spin relaxation times, rendering them promising c…
Current-based RF charge sensing in a carbon nanotube
Marta Cagetti, Stefan Forstner, Victor Champain +8
Ultra-sensitive charge detection is a widely used tool for quantum electronics with applications in quantum information processing and in probing the physics of condensed matter sy…
Tunable nonlinear electromechanics at the zero-point motion scale
Christoffer B. Møller, Roger Tormo-Queralt, Elsa Vázquez-Rodríguez +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. Salvía-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
