oferta de trabajo en Catalan Institute of Nanoscience and Nanotechnology

 The Catalan Institute of Nanoscience and Nanotechnology (ICN2), located in Barcelona, Spain, is a non-profit research institute created in 2003 to foster cutting–edge research in nanoscience and nanotechnology. ICN2 is a member of the Barcelona Institute of Science and Technology and the Catalonian network of excellenceCERCA. It is one of eighteen Severo Ochoa Centres of Excellence in Spain. It is located at the Bellaterracampus of the University Autonomous of Barcelona in a purpose-designed building with state-of-the-artfacilities. ICN2 researchers have access to shared resources, including an in-house small clean room facility,the clean room of the National Centre for Microelectronics (CSIC-CNM) and the ALBA Synchrotron. ICN2 hasabout 230 full-time researchers including PhD Students, Postdoctoral Researches, Specialized Techniciansand Group and Division Leaders. Research is conducted via independent research lines, broadly grouped intotwo areas 1) Nanophysics, including atomic-scale material studies of fundamental and applied character,theoretical studies, nanoelectronic devices, nanophononics, nanophotonics, NEMS, spintronics andnanofabrication and 2) Nanochemistry and Nanobiochemistry.Job Title: Postdoctoral ResearcherResearch area or group: Phononic and Photonic Nanostructures GroupDescription of Group/Project:Topological bosonics: design and optimization of topological materialsIn January 2019 we started a 5-year EU FET-Proactive project on Topological matter in collaboration with thegroup of Quantum Photonics at the Niels Bohr Institute in Copenhagen and groups working on electronictopological insulators such as the Physics and Engineering of Nanodevices group at ICN2 and the group ofTopological Insulators at Würzburg University. Our main goal is to gain a radically new fundamentalknowledge of the interactions and correlations between topological excitations (photons, phonons andelectrons) in hybrid topological systems for efficient transfer and manipulation of classical and quantuminformation by a suitable combination of specific materials and structures, e.g. topological insulators andphotonic crystals, and by designing device-like structures that host more than one topological quasiparticlePhotonic Topological Materials.

The technology breakthrough will result from the combination of the properties of photonic crystals(on III-V, and Si semiconductors) with unique topological structures for confining and protecting the edgestates from localization and scattering with defects and a detailed study of emission, and subsequentpropagation, of photons in topologically protected modes.To develop topological photonic and phononic nanostructures in planar and vertical multilayer structures anduse them to advance the fundamental understanding of the interaction between trivial (chiral) quasiparticleswith their topologically protected counterparts.Requeriments:We are looking for an experienced theorist with background in photonics, phononics and/or optomechanics,preferably expert on analytical tools more than numerical models, and ideally some expertise in grouptheory. From novel designs of optomechanical crystals, we need to delve into group theory and bandstructure engineering to develop low-loss waveguides based on optomechanical crystals hosting topologicaledge states with arbitrary shape. In particular, we are developing semi-analytical models to treat complexphotonic and phononic low-dimensional structures to implement topological properties with topologicalglobal properties that are, to a certain extent, immune to small perturbations such as unavoidablefabrication disorder. The candidate will conduct analytical theory combined with simulations using grouptheory to specifically design and optimize topological waveguides for near-infrared photons and phonons ina wide spectral range from few to 100’s of GHz.Summary of conditions: Full time work (37,5h/week) Contract Length: two years (with possible extension to a third year) Salary will depend on qualifications and demonstrated experience. Support to the relocation expenses. Life Insurance.Estimated Incorporation date: January 2021How to apply:All applications must be made via the ICN2 web page https://jobs.icn2.cat/job-openings/264/postdoctoralresearcher-phononic-and-photonic-nanostructures-group and include the following: A cover letter. A full CV including contact details. 2 Reference letters or referee contacts.3Deadline:Informal enquiries regarding the vacancy can be made to Dr. P.
