Our everyday life is unimaginable without wireless information and communication technologies. Since 2019, 5G digital systems offer improved speed, bandwidth, and decreased energy consumption. Mobile operators invest $160 billion worldwide in the deployment of 5G each year. Over the last decades, RF filters based on Surface Acoustic Wave (SAW) occupied the entire market. But their usage for 5G high-band (26 GHz in EU) is impossible. Moreover, the utilisation of Bulk Acoustic Waves (BAWs) is still left to be explored due to their significant damping, challenges with confinement, and complex fabrication. The solution is offered by the propagating excitation in the spin system of a solid magnetic body - Spin Waves (SWs), which can efficiently replace acoustic waves in the RF devices for all frequency bands. The key advantages of SWs are: (i) frequency range from 1GHz up to hundreds of GHz, (ii) manufacturability of SW transducers using conventional photolithography, (iii) strong confinement of SWs, and (iv) additional nonlinear functionalities. The ERC StG MagnonCircuits finished with utmost success (40 articles) and delivered the methodology and know-how for fabrication and characterisation of magnonic nano-structures; explored SW physical properties in them; and identified robust, reliable, and efficient phenomena for applications. In the 5G-Spin project, I will develop fully functioning, bias field-free, and industry-ready SW-based RF filters and multiplexers for mid- and high-band 5G communication systems.

WILA19-91 main aim is to to bridge the gap between intellectual history and labor history, and through this methodological innovation not only highlight the disparity between intellectual labor and intellectual achievements, but also challenge historiography's perception of the latter. While intellectual history predominantly focuses on artistic and intellectual achievements, it often fails to question the underlying conditions that made such achievements possible. Consequently, many marginalized groups have been excluded from the canon, as they did not have the necessary working conditions to consistently produce intellectual or artistic labor. The WILA19-91 project focuses specifically on women's intellectual labor from 1919 to 1991, utilizing Yugoslavia as a transnational laboratory space to observe the dynamics of intellectual and artistic labor across different time periods, generations, social classes, nationalities, and ethnicities. The project's outcomes will contribute to establishing new norms for reevaluating artistic and intellectual achievements, ultimately broadening and decolonizing the canon. The project examines work conditions, considering the power structures associated with intellectual authorities, social prejudices, intimate beliefs, and invisible social agreements at various times. To achieve this, it explores the intersection of intellectual, labor, and gender history. By drawing on a diverse range of sources in different languages (Slovene, Croatian, Serbian, German) and amplifying the voices of women from ethnic and sexual minorities, this project will investigate working conditions, attitudes towards work, legislative changes, family dynamics, public reception, financial compensation and care work, in order to understand the division between intellectual work (as labor) and being an intellectual (as a status).

This project will bring Matthew Pelowski to Vienna University to undergo a unique two-way program of knowledge transfer and to conduct an innovative, integrated behavioral/neural study of art perception using causative brain manipulation via TMS (Transcranial Magnetic Stimulation). Art is a unique feature of human life. Uncovering how it affects us requires joint expertise in aesthetics, psychology and neuroscience. Employing TMS, we will systematically manipulate three key brain regions (prefrontal, temporal and parietal), while individuals view a selection of art. Cognitive, emotional and evaluative reactions will be recorded via specially designed survey and assessed via a cognitive model which integrates these factors, both of which were created by Dr. Pelowski and which he will introduce to the Vienna group. Simultaneously, Dr. Pelowski will be supported by leading experts in art’s neural study under guidance of host Dr. Leder, and will receive training in TMS. By comparing responses to a control and using Dr. Pelowski's methodology, we will collect a comprehensive within-subject dataset of specific impact of brain regions on art experience. This research will provide the “next step” for clarifying previous cognitive and neurological findings, achieving their integration. It will clarify general questions of brain role in emotion and evaluation. It will also have wide inter-sectoral application to dementia research and art therapy, which will be explored with experts in Leder’s group, and will be a breakthrough to future study of integrated neuroaesthetics and psychology of art. This project will also create a new research direction, expanding from an established center at University of Vienna, continuing a key tradition in empirical aesthetics. It also creates a point of continuing collaboration between Vienna, US and EU, and will further launch the career of Dr. Pelowsk and extend his proficiency to causative brain research.

We propose the exploration of many-body quantum physics with a new experimental platform, based on the optically levitated and cooled arrays of spherical nanoparticles with strong and controllable interactions. The recent works by the host institution demonstrated the cavity assisted cooling of a single nanoparticle to its motional quantum ground state as well as the simultaneous trapping of two nanoparticles with full control over the interactions between them. In this work we shall extend these results to the multiple particles. This will be on the one hand an important milestone towards achieving the many-body regime and on the other hand, the first observation of the cavity assisted cooling of an array of nanoparticles via coherent light scattering. The realisation of this milestone will enable us to study the system’s non-equilibrium relaxation after precise perturbation protocols. Using the natural isolation from the environment, we shall study the thermalisation of a nearly isolated few-particle quantum system. Depending on the energetic landscape, as well as on the nature and range of interactions, we expect to observe motional pre-thermalisation, or the absence of thermalisation with the onset of the Anderson localisation or the Many-Body Localisation of phonons. Finally, we shall explore the controllable non-reciprocity of the inter-particle interactions by breaking the directional symmetry of the inter-particle forces by conferring to them the direction dependent phases. Combining this with the dissipative nature of these forces, we aim at implementing a specifically tailored non-hermitian Hamiltonian describing the constant intensity waves.
