Mathematically they require breaking of time-reversal symmetry, typically achieved using magnetic materials and more recently using the quantum Hall effect, parametric permittivity modulation or Josephson nonlinearities. Here we demonstrate an on-chip magnetic-free circulator based on reservoir-engineered electromechanic interactions. Directional circulation is achieved with controlled phase-sensitive interference of six distinct electro-mechanical signal conversion paths. The presented circulator is compact, its silicon-on-insulator platform is compatible with both superconducting qubits and silicon photonics, and its noise performance is close to the quantum limit. With a high dynamic range, a tunable bandwidth of up to 30 MHz and an in situ reconfigurability as beam splitter or wavelength converter, it could pave the way for superconducting qubit processors with multiplexed on-chip signal processing and readout."}],"oa_version":"Published Version","scopus_import":"1","month":"10","intvolume":" 8","publication_identifier":{"issn":["20411723"]},"publication_status":"published","file":[{"content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_id":"5145","checksum":"b68dafa71d1834c23b742cd9987a3d5f","file_size":1467696,"date_updated":"2020-07-14T12:48:06Z","creator":"system","file_name":"IST-2017-867-v1+1_s41467-017-01304-x.pdf","date_created":"2018-12-12T10:15:25Z"}],"language":[{"iso":"eng"}],"issue":"1","volume":8,"license":"https://creativecommons.org/licenses/by/4.0/","ec_funded":1},{"publist_id":"6864","author":[{"orcid":"0000-0003-3650-940X","full_name":"Alistarh, Dan-Adrian","last_name":"Alistarh","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","first_name":"Dan-Adrian"},{"last_name":"Kopinsky","full_name":"Kopinsky, Justin","first_name":"Justin"},{"first_name":"Jerry","full_name":"Li, Jerry","last_name":"Li"},{"first_name":"Giorgi","id":"3279A00C-F248-11E8-B48F-1D18A9856A87","last_name":"Nadiradze","full_name":"Nadiradze, Giorgi","orcid":"0000-0001-5634-0731"}],"article_processing_charge":"No","external_id":{"isi":["000462995000035"]},"title":"The power of choice in priority scheduling","citation":{"mla":"Alistarh, Dan-Adrian, et al. “The Power of Choice in Priority Scheduling.” Proceedings of the ACM Symposium on Principles of Distributed Computing, vol.

To remove an element, we pick two queues at random, and remove the element of lower label (higher priority) among the two. The cost of a removal is the rank of the label removed, among labels still present in any of the queues, that is, the distance from the optimal choice at each step. Variants of this strategy are prevalent in state-of-the-art concurrent priority queue implementations. Nonetheless, it is not known whether such implementations provide any rank guarantees, even in a sequential model. We answer this question, showing that this strategy provides surprisingly strong guarantees: Although the single-choice process, where we always insert and remove from a single randomly chosen queue, has degrading cost, going to infinity as we increase the number of steps, in the two choice process, the expected rank of a removed element is O(n) while the expected worst-case cost is O(n log n). These bounds are tight, and hold irrespective of the number of steps for which we run the process. The argument is based on a new technical connection between "heavily loaded" balls-into-bins processes and priority scheduling. Our analytic results inspire a new concurrent priority queue implementation, which improves upon the state of the art in terms of practical performance."}],"oa_version":"Submitted Version","volume":"Part F129314","publication_identifier":{"isbn":["978-145034992-5"]},"publication_status":"published","language":[{"iso":"eng"}]},{"intvolume":" 833","month":"12","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1705.03720"}],"scopus_import":"1","oa_version":"Submitted Version","abstract":[{"lang":"eng","text":"The chaotic dynamics of low-dimensional systems, such as Lorenz or Rössler flows, is guided by the infinity of periodic orbits embedded in their strange attractors. Whether this is also the case for the infinite-dimensional dynamics of Navier–Stokes equations has long been speculated, and is a topic of ongoing study. Periodic and relative periodic solutions have been shown to be involved in transitions to turbulence. Their relevance to turbulent dynamics – specifically, whether periodic orbits play the same role in high-dimensional nonlinear systems like the Navier–Stokes equations as they do in lower-dimensional systems – is the focus of the present investigation. We perform here a detailed study of pipe flow relative periodic orbits with energies and mean dissipations close to turbulent values. We outline several approaches to reduction of the translational symmetry of the system. We study pipe flow in a minimal computational cell at Re=2500, and report a library of invariant solutions found with the aid of the method of slices. Detailed study of the unstable manifolds of a sample of these solutions is consistent with the picture that relative periodic orbits are embedded in the chaotic saddle and that they guide the turbulent dynamics."}],"volume":833,"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["00221120"]},"status":"public","type":"journal_article","_id":"792","department":[{"_id":"BjHo"}],"date_updated":"2023-09-27T12:17:35Z","oa":1,"quality_controlled":"1","publisher":"Cambridge University Press","date_created":"2018-12-11T11:48:32Z","date_published":"2017-12-25T00:00:00Z","doi":"10.1017/jfm.2017.699","page":"274 - 301","publication":"Journal of Fluid Mechanics","day":"25","year":"2017","isi":1,"project":[{"_id":"25636330-B435-11E9-9278-68D0E5697425","grant_number":"11-NSF-1070","name":"ROOTS Genome-wide Analysis of Root Traits"}],"title":"Relative periodic orbits form the backbone of turbulent pipe flow","article_processing_charge":"No","external_id":{"isi":["000414641700001"]},"author":[{"orcid":"0000-0003-0423-5010","full_name":"Budanur, Nazmi B","last_name":"Budanur","first_name":"Nazmi B","id":"3EA1010E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Kimberly","last_name":"Short","full_name":"Short, Kimberly"},{"full_name":"Farazmand, Mohammad","last_name":"Farazmand","first_name":"Mohammad"},{"first_name":"Ashley","full_name":"Willis, Ashley","last_name":"Willis"},{"full_name":"Cvitanović, Predrag","last_name":"Cvitanović","first_name":"Predrag"}],"publist_id":"6862","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"chicago":"Budanur, Nazmi B, Kimberly Short, Mohammad Farazmand, Ashley Willis, and Predrag Cvitanović. “Relative Periodic Orbits Form the Backbone of Turbulent Pipe Flow.” Journal of Fluid Mechanics.

This process in principle permits the co-fabrication of silicon photonic and mechanical elements, providing a route towards chip-scale integration of electro-opto-mechanical transducers for quantum networking of superconducting microwave quantum circuits.
