Ghanem’s PhD defense
Congratulations to Ghanem for his successful PhD defense! Even though this was late of Friday, it was great to see a packed room and a committee asking plenty of questions!
Cassandra presents at Colorado AI Summit
Cassandra presented a lightning talk and a poster at the first Colorado AI Summit. This event was organized by the Computer Science Department to bring together academia, industry, and government on AI-related topics. Cassandra’s work on prediction of material defect thresholds is a novel avenue to use CNNs with a direct physical interpretation.
Ally’s PhD defense
Congratulations to Ally who successfully defended her PhD! Ally is the first PhD in the group and has set an excellent standard for those to come. Very well done!
Manipulating bandgap in magnonic crystals
Congratulations to Pietro Micaletti for publishing his second work on the manipulation of band structure in magnonic crystals due to modifications in magnetic parameters. This work published in J. App. Phys. further discusses the analogy between a metal and insulator transition in magnonic crystals.
Spin-superfluid-mediated soliton dynamics
Congratulations to Medhanie who published a paper on the interaction between solitons mediated by spin superfluids in Phys. Rev. B. In this study, we nucleated metastable solitons by spin injection. The region between these solitons is a “well” in which a spin superfluid is established. Depending on the relative sign of the initial soliton, the interaction leads to the ejection and renucleation of solitons under the injection region outside or inside of the well.
This work is another step towards the understanding of spin superfluids and their interaction with nonlinear structures.
Frequency combs in macroscopic ASIs
Our work on frequency combs in macroscopic ASIs was published in Phys. Rev. Applied and received Editors’ Suggestion designation. This was a very fun project in collaboration with Prof. Bozhko’s group.
Congratulations to Renju and Lawrence for this publication!
More details on this work can be found in our press release.
Magnon propagation through tailored magnetization distributions
Congratulations for Pietro Micaletti who published his work on magnons through sinusoidal magnetization distributions in the Journal of Magnetism and Magnetic Materials. This work demonstrates how the magnetization distribution can act in itself as a magnonic crystal, leading to large bandgaps and localizing modes.
This work is part of the ongoing collaboration with Prof. Feredico Montoncello in Ferrara and some of these simulations were performed at UCCS during Pietro’s visit.
Group at APS Global Physics Summit
We had a great week at the APS Global Physics Summit in Anaheim. UCCS had a great representation at the conference. Our group was joined by Lauren Kim from Wyoming U and Prof. Troy Dion from Tohoku University.
Lawrence to research at ETH
Lawrence will be visiting the group of Prof. Yiwen Chu at ETH Zurich to perform research on spin-acoustics interactions. Prof. Chu’s group is investigating the coupling between an acoustic resonator and spins in silicon vacancy centers (Si-V centers).
Within our group, Lawrence has been an exceptional undergraduate researcher. He developed and performed simulations on the macroscopic artificial spin ices and performed micromagnetic simulations of the magneto-toroidal ASI. In total, he contributed to three manuscripts. Lawrence was also awarded UCCS’s URA and was a Barry Goldwater Scholarship recipient.
We wish Lawrence continued success in his future research at ETH and future opportunities!
