Excited to participate at the Workshop on Gauge Theories and Gravity 1-3 July 2022 with such a diverse range of related Physics talks. Happy to contribute an invited talk on “Magnetic Skyrmions for Nanocomputing”. Inspired by earlier theoretical work from the community on conservation laws as suitable moments of a topological density and what these can tell us about the dynamics of topological and non-topological textures (e.g. N. Papanicolaou and T. N. Tomaras, Nuclear Physics B, 360, 425–462 (1991)) (the Landau-Lifshitz equation can be viewed as a U(1) gauge theory), our presentation aimed to provide a link from earlier theoretical results to modern results from the exciting field of Skyrmionics! Subsequently, we showed how by manipulating nanoscale skyrmionic spin textures embedded in thin-film devices with electrical currents, and exploiting their topology, may be used for neuromorphic computing and nanocomputing.
Looking forward to participating and contributing an invited talk on our recent research on magnetic skyrmions and nanocomputing at the “Current Research in Magnetic Skyrmions” by the UK Magnetics Society which will take place at the University of Central Lancashire in Preston, on Wednesday the 8th of June 2022.
Very happy to have participated at the EPSRC International Network for Spintronics Early Career Researchers Meeting in the University of Leeds with 125 attendees from 14 countries and contribute a talk on Magnetic Skyrmions for Nanocomputing.
A video explaining our recent theoretical/computational paper on “Tunable terahertz oscillation arising from Bloch-point dynamics in chiral magnets” recently published at the Physical Review Research journal, by lead author, our PhD student Yu Li. A collaboration between the University of Manchester with the Metal Physics and Technology group at the ETH Zürich.
Our recent theoretical/computational paper on “Tunable terahertz oscillation arising from Bloch-point dynamics in chiral magnets” has now been published at the Physical Review Research journal! Congratulations to the lead author, our PhD student Yu Li. The work arose from a collaboration between the University of Manchester with the Metal Physics and Technology group at the ETH Zürich. This work reveals that the formation/annihilation processes of skyrmions will give rise to an emergent electric field with a frequency in the THz regime. The electric signal is due to the ultra-fast Bloch-point propagation, and both the amplitude and frequency can be tuned by the manipulation of Bloch-point dynamics. Our study provides a concept of directly exploiting topological singularities that may be relevant for THz skyrmion-based electronic devices.
Congratulations to our PhD student, Yu Li, for winning the Best Poster award at the ‘Skyrmions in Magnetic Materials‘ seminar in Bad Honnef, Germany. He presented a poster on our recent work on ‘Tuneable Bloch-point dynamics during switching of skyrmions and antiskyrmions in chiral magnets‘, which is also available on the arXiv (link).
Really excited to participate in the British-German WE-Heraeus-Seminar on ‘Skyrmions in Magnetic Materials’ at the Physikzentrum Bad Honnef (1st – 5th Dec., 2019). We participated with two of our PhD students, Yu Li and Runze Chen, who presented posters relevant to Bloch point dynamics, and neuromorphic computing, respectively.
Really excited to participate the 12th International Symposium on Hysteresis Modeling and Micromagnetics (HMM2019) in Crete, Greece from 19th-22nd of May, 2019. Yu Li, a PhD member of our team, presented a talk in the first session “Magnetic Solitons I”, with the title “Controllable THz Bloch-point propagation in the switching process of magnetic skyrmions“. We also presented a poster from our recently published work “Collective antiskyrmion-mediated phase transition and defect-induced melting in chiral magnetic films“.
Excited to participate at the Skyrmion workshop at Trinity Hall, the University of Cambridge, organised by the U.K.’s Skyrmion Project, from Tuesday 28th-Thursday 30th of August 2018. Happy to contribute a talk and participate in the panel discussion : “Prospects for Disruptive Skyrmion Technology”.
Excited to be at the the Future Perspectives on Novel Magnetic Materials workshop taking part from May 29-June 3, 2018 in beautiful Santorini, Greece. The workshop’s program focused on the development of high anisotropy magnetic materials, ii) non-collinear spin structures that exhibit skyrmion and anti-skyrmions and iii) magnetic materials that display topological transport and electronic properties. Happy to be invited to contribute a talk on Thursday the 31st of May, on recent numerical and experimental results on magnetic skyrmions.
