Projet Fractional (Horizon 2020, appel à projets 2014)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Physics
Statut du projet : CLOSED

With the advent of topological phases, we have recently witnessed a revolution in our understanding of different phases of matter. They are described by tools borrowed from mathematical topology, unlike more familiar phases such as (ferro)magnets, classified in terms of symmetry breaking. Within these topological phases, fractionalized states of matter are of the most exotic, intriguing and potentially useful kind. They result from the delicate interplay between strong correlations among its constituents and the topological nature of the parent non-interacting state. They carry fractional quantum numbers and topologically protected excitations, insensitive to local system details (e.g. impurities) and key to efficient, fault-tolerant quantum computation. The fractional quantum Hall effect (FQHE) is still the hallmark of such phases but it needs strong magnetic fields and low temperatures to be realized, severely constraining the latter groundbreaking scientific leap. Thus, this project aims to reach a new milestone concerning fractionalized phases to foster possible realizations and open the next door towards the quantum computing revolution. To this end, an innovative interedisciplinary approach is required. First, a numerical study beyond the widely used exact diagonalization will characterize fractional Chern insulators (FCI), FQHE analogues that dispose of the need of external magnetic fields, strongly focusing on experimentally relevant features, in particular dynamical signatures, still largely unexplored. Second, it proposes a new ’topologically trivial to FCI’ route to realize these phases while critically assessing existing proposals and the role of possible competing orders that can jeopardize the emergence of fractionalization. Lastly, it will investigate effective quantum field theories that can generalize fractionalization to three dimensional topological phases in interacting Weyl semi-metals, providing an new landmark in the search for these states.

Projet SPECTER (Horizon 2020, appel à projets 2019)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : CLOSED

With the current technology of transistors reaching characteristic sizes of a few nanometers, and heating effects becoming more severe, the regular functionality of processors is at stake. In the next few years, new technologies are required to sustain the increasingly high demands imposed by the consumer electronics industry worldwide. Among the wide range of proposed options, spintronics is considered to be one of the leading candidates to fill this gap, backed by recent proposals for spin-based computation using magnetoelectric spin-orbit devices. In these devices, the magnetic state of a ferromagnetic material is read through the conversion of spin currents in charge currents, where two resistance levels can be unambiguously detected depending on the magnetization direction of the ferromagnet, i.e. a “1” and a ”0” state. The main goal of SPECTER is to find the most suitable material exhibiting large spin-to-charge conversion efficiencies combined with large resistivities, allowing the generation of high output voltages for a subsequent writing step. To achieve this result, a careful balance between adequate materials beyond the conventional high spin-orbit coupling metals, and device fabrication of nanostructures that maximize spin-to-charge conversion detection needs to be achieved. With this proposal, we want to explore nanostructured topological insulators and correlated oxides fabricated by industry-friendly techniques, such as sputtering and e-beam lithography, while benchmarking them for future spin-based devices. This way, SPECTER not only poses a revolutionary step towards the next generation of processors, but also aims at acquiring scientific knowledge with technological applications to be useful for both academia and industry. Moreover, the ultimate goal of SPECTER is to offer high-quality interdisciplinary research training for an aspiring young researcher helping him to build a promising scientific research career.

Panel : Physics
Statut du projet : CLOSED

With the discovery of topological order, condensed matter physics has witnessed a revolution in how phases of matter ought to be defined and characterized. Unlike spins aligning in a magnet, topological phases are not classified by symmetry breaking but instead require nonlocal invariants that relate to the mathematical domain of topology. This theme took a turn with the finding that even common electronic band structures can feature topological invariants in the presence of appropriate symmetries. Ever since, many such symmetry protected topological (SPT) states have been predicted and arranged into a unifying table. These developments have been accompanied by the actual realization of various topological band insulators that feature striking properties including protected metallic edge states and proposed exotic fractionalized excitations, which may provide a route to fault-tolerant topological quantum computing. Now, the field is approaching a new exciting turning point as indications are emerging that other parts of the modern 'Mendeleev table' exist involving band structures that do not pertain to equilibrium ground states. On the verge of this milestone, this project will take a pioneering role and investigate such SPT phases in the context of periodically driven quantum systems and magnon excitation spectra. The objective is to uncover the underlying general classification principles, which will provide a guide to engineering novel states and accordingly new physics. To this end, we will apply a multidisciplinary approach combining state-of-the-art handles on SPT order, insights from analytically tractable models and numerics. In particular, we envision that naturally present crystal symmetries will play a prominent role here -one that has yet to be appreciated- much as they do in equilibrium SPTs. Together with a complementary generalization of physical observables, we expect this action to pave the way to a new chapter in the success story of SPT phases.

With the increasing demand of broadband connectivity, satellite communications are receiving significant attention, since the requirement for infrastructure in Earth is minimum. However, broadband low-latency satellite connectivity entails several challenges from the point of view of radiofrequency engineering: antennas with high gain, beam steering capabilities and broad bandwidth are required. Current solutions are either parabolic dishes with mechanical steering, which are bulky and require maintenance, or phased- arrays with electronic steering, which are low-profile but significantly expensive. Therefore, a reconfigurable low-cost high-gain antenna with no moving parts and small size is an important market niche and can revolutionize satellite communications. In this way, the current limitations of connectivity to mobile users, such as in maritime or aviation, or in isolated or poor areas, where expensive infrastructure cannot be deployed, can be overcome. The project proposes a novel low-profile and low-cost solution for broadband satellite communications based on the fusion of two fields: metamaterials and leaky-wave antennas. By combining such an inexpensive antenna with a metasurface, the antenna characteristics can be enhanced to meet the challenging requirements of satellite services at a very low cost and size. The researcher will have the opportunity to learn this cutting-edge technology from the pioneer group in this kind of solutions at University of Toronto,and import this knowledge into Europe to contribute to developing the satellite communication industry and open new markets. Moreover, the knowledge of the group at the University of Malaga (including the researcher) about both broadband leaky-wave antennas and active components will be crucial to develop such a broadband solution, which must implement electronic reconfigurability.

With the next-generation laser facilities at the 10-100 petawatt (PW) level, e.g., the EU-funded Extreme Light Infrastructure (ELI) facilities, the physical picture of relativistic laser-plasma interaction found so far with PW scale lasers may not be valid anymore. It enters a new regime, where at least the following distinct features are expected to appear: 1) Dense electron-positron pairs and high energy γ-photons production via quantum electrodynamics (QED) processes; 2) Significant radiation recoil during electron and positron quiver motion in laser fields; 3) As large relativistic electron mass as proton mass, representing a unique plasma state. To fully exploit and understand this highly complex system, we will investigate some fundamental problems including the propagation of ultra-relativistic laser pulses in plasma, their energy dissipation and allocation to energetic particles and photons, and their scaling to laser and target parameters. Understanding of these problems is essential in order to manipulate QED effects for advanced applications, e.g., generation of high peak flux 10GeV protons, modelling of some energetic astrophysical phenomena, etc. This system is compound with collective and kinetic nonlinearities through wave-wave interactions, wave-particle interactions, and new particle generation and annihilation via QED processes. All these will be treated in a self-consistent way by developing an advanced particle-in-cell (PIC) code with QED processes included. The researcher Wei-Min Wang has nearly 10 years of experience in developing PIC codes for various applications. He was awarded the prestigious IUPAP Young Scientist Award in Computational Physics in 2015. The proposed research and training will further bring the researcher to an independent and matured theoretician. The research achievements will provide significant support to European projects associated with the ELI facilities, which will be ready for experiments in the near future.

Projet XeRo (Horizon 2020, appel à projets 2020)

Panel : Information Science and Engineering
Statut du projet : SIGNED

With the rapid development of high speed rail system, ground vibration mitigation solutions are desperately needed. As a novel vibration mitigation method, metamaterial can theoretically yield excellent performance in shielding dynamic waves in broad frequency bands. However, the application of metamaterials in railway-induced vibration mitigation is a very recent and ongoing topic. Therefore, the XeRo project aims to establish new and practical contribution towards a better understanding of the mitigation effects by metamaterials for railway-induced environmental vibrations. The experienced researcher (ER) will: 1) investigate the dominant frequencies of railway environment based on a 3D coupled train-track-soil interaction model; 2) design and develop the metamaterial based on the locally resonant mechanism; 3) characterize and optimize the metamaterial with respect to viscoelastic multi-layered soils; and 4) demonstrate the mitigation effect of the metamaterial on railway environmental vibration. Implemented at the University of Porto, and supervised by Prof Rui Calcada, the XeRo project will allow the ER to diversify her individual competence by developing skills in railway dynamics, academic dissemination and networking; student supervision; and research management and leadership. The XeRo project will also strongly benefit the ER’s inter-sectoral and interdisciplinary expertise and strengthen her international network considering a secondment will be carried out at the University of Birmingham. A two-way transfer of knowledge is guaranteed since the XeRo project combines the ER’s expertise in metamaterial design and railway vibration evaluation and the host’s expertise in the numerical modelling and dynamic analysis of train-induced ground vibrations. Therefore, the XeRo project will contribute to Europe’s knowledge-based society, policy makers and rail industries by providing invaluable knowledge on the novel vibration mitigation solution in railways.

With various emerging latency-sensitive applications, e.g., V2V (vehicle-to-vehicle) automation, smart power systems (i.e., smart grids), Internet of things (IoT) and smart factory (industry 4.0), low-latency communication is becoming more and more important. To meet increasing demands, there have been substantial research activities on low-latency communications recently. Meanwhile, many applications also have high requirements on reliability. These schemes with high requirements on reliability and latency are often termed high-reliability low-latency (HRLL) communications. A common approach to achieve low-latency is finite length coding/transmission blocks. However, due to finite code length, it is rather challenging to achieve high reliability and low latency simultaneously. Moreover, in many scenarios, high data rates are also needed. Thus, it is rather valuable to study communication and coding schemes capable of simultaneously improving reliability, latency and rates. Network coding, originally proposed for increasing network throughput, has shown benefits in latency, throughput and reliability, respectively. However, the study of network coding for HRLL communications is still very limited. Thus, the main objective of the project is to systematically investigate network coding for HRLL communications. We will find the fundamental limits of HRLL networks with network coding. We will optimize network coding schemes and propose efficient communication strategies to improve latency and reliability performance under practical constraints. The outgoing mobility will be hosted Electrical Engineering department, Princeton University, USA, with excellent academy environments and the applicant will be trained in advanced knowledge, management and pedagogy skills, in addition to research topics and methods.

Statut du projet : CLOSED

Within eight years, metal halide perovskite materials become a new class of semiconducting materials for optoelectronic device application. Their unique and attractive optoelectronic properties, e.g., high crystallinity, low-cost, solution processable with large area deposition, direct band gap nature, low defect density, high color purity (narrow PL emission), tunable optical bandgap, long diffusion length, and balance and high charge carrier mobility. These properties make them attractive and potential candidates for light emitting diodes (LEDs) also. The green and red emissive perovskite-based LEDs efficiency reached ~10%, which is equal to the organic light emitting diodes (OLEDs) at lab scale. But still, blue emissive PeLED efficiency is lower as compared to green and red PeLEDs. The poor stability, poor charge balance, and low photoluminescent are major problems to limit blue PeLED efficinecy. In this proposal, I aims to address these challenges and demonstrate efficient and stable blue PeLED. The research work will be organized according to the following key objectives. 1) Design of blue emissive quasi 2D perovskite material by first-principles calculation (with the support of host organization), b) Deposition of high quality and pinhole-free blue quasi 2D thin film by using various deposition method and their characterization, and c) Fabrication of efficient and stable blue emissive quasi 2D PeLED beyond state of the art, by using device engineering and device physics investigation. This project provides basic scientific knowledge of quasi 2D perovskite materials for blue emissive PeLEDs. The expected results of this project are bandgap engineering of quasi 2D perovskite materials for blue emission with good optoelectronic properties, efficient and stable blue PeLED. Also, I will learn the synthesis of quasi 2D materials from the host organization that will be improved my interdisciplinary knowledge and research skills. The efficient blue PeLED is us
