Their exceptional properties, such as low mass and high quality factor, make them also very appealing for force sensing experiments. In this Letter, we propose a method for detecting and ultimately controlling nuclear spins by directly coupling them to high-frequency resonators via a magnetic field gradient. Dynamical backaction between the sensor and an ensemble of nuclear spins produces a shift in the sensor's resonance frequency, which can be measured to probe the spin ensemble. Based on analytical as well as numerical results, we predict that the method will allow nanoscale magnetic resonance imaging with a range of realistic devices. At the same time, this interaction paves the way for new manipulation techniques, similar to those employed in cavity optomechanics, enriching both the sensor's and the spin ensemble's features.} } + @article{slim2023optomechanical, - title={Optomechanical realization of the bosonic Kitaev-Majorana chain}, - author={Slim, Jesse J and Wanjura, Clara C and Brunelli, Matteo and del Pino, Javier and Nunnenkamp, Andreas and Verhagen, Ewold}, - journal={arXiv preprint arXiv:2309.05825}, - year={2023}, - bibtex_show = {true}, - abbr = {in review}, - abstract = {The fermionic Kitaev chain is a canonical model featuring topological Majorana zero modes.

We report the experimental realization of its bosonic analogue2 in a nano-optomechanical network, in which the parametric interactions induce beam-splitter coupling and two-mode squeezing among the nanomechanical modes, analogous to hopping and p-wave pairing in the fermionic case, respectively. This specific structure gives rise to a set of extraordinary phenomena in the bosonic dynamics and transport. We observe quadrature-dependent chiral amplification, exponential scaling of the gain with system size and strong sensitivity to boundary conditions. All these are linked to the unique non-Hermitian topological nature of the bosonic Kitaev chain. We probe the topological phase transition and uncover a rich dynamical phase diagram by controlling interaction phases and amplitudes. Finally, we present an experimental demonstration of an exponentially enhanced response to a small perturbation3,4. These results represent the demonstration of a new synthetic phase of matter whose bosonic dynamics do not have fermionic parallels, and we have established a powerful system for studying non-Hermitian topology and its applications for signal manipulation and sensing.}, + author = {Slim, Jesse J. and Wanjura, Clara C. and Brunelli, Matteo and del Pino, Javier and Nunnenkamp, Andreas and Verhagen, Ewold}, + date = {2024/03/01}, + date-added = {2024-03-28 15:32:42 +0700}, + date-modified = {2024-03-28 15:32:42 +0700}, + doi = {10.1038/s41586-024-07174-w}, + id = {Slim2024}, + isbn = {1476-4687}, + journal = {Nature}, + number = {8005}, + pages = {767--771}, + title = {Optomechanical realization of the bosonic Kitaev chain}, + url = {https://doi.org/10.1038/s41586-024-07174-w}, + volume = {627}, + year = {2024}, + bdsk-url-1 = {https://doi.org/10.1038/s41586-024-07174-w}} + @article{wanjura2022quadrature, title = {{Quadrature nonreciprocity: unidirectional bosonic transmission without breaking time-reversal symmetry}}, author = {Wanjura, Clara C. and Slim, Jesse J. and del Pino, Javier and Brunelli, Matteo and Verhagen, Ewold and Nunnenkamp, Andreas}, diff --git a/assets/pdf/CV_JdP.pdf b/assets/pdf/CV_JdP.pdf index 7853f26..f4fdddf 100644 Binary files a/assets/pdf/CV_JdP.pdf and b/assets/pdf/CV_JdP.pdf differ
