Hybridization of Multiple Vibrational Modes via Strong Coupling Using Confined Light Fields

Congratulations to our fourth year PGRs Kishan Menghrajani, the main author of the paper Hybridization of Multiple Vibrational Modes via Strong Coupling Using Confined Light Fields, which was recently published in Advanced Optical Materials. The co-authors were fourth year PGR Henry Fernandez and supervisors Geoffrey R. Nash and William L. Barnes.

The paper is on strong coupling of multiple vibrational resonances of the same molecular unit with confined light fields. The results suggest that strong coupling might be used to manipulate vibrational resonances in a richer and subtler way than previously considered, opening a path to greater control of molecular systems and molecular processes via vibrational strong coupling.

Both Kishan and Henry have been busy this year, with Kishan presenting at Liebniz Institute of Photonics Technology and earlier this year, Henry giving a talk at the prestigious Nanometa conference.

David Newman presents poster at York-Tohoku-Kaiserslautern Research Symposium

On 12th-14th June, first year PGR David Newman attended the York-Tohoku-Kaiserslautern Research Symposium on “New Concept Spintronic Devices”. The symposium is a result of the JSPS Core-to-Core programme that pairs Japanese universities with world-leading universities.

David presented a poster titled”Time-resolved X-ray detected ferromagnetic resonance measurements of a CoFe/NiO/Fe/NiFe multilayer structure”. This involved using X-ray techniques to observe an AC spin current propagating through an antiferrromagnetic NiO layer.

David learnt a lot about how people are incorporating spintronic concepts into devices and novel techniques for studying spin phenomena as well as the conference providing a good opportunity to network.

Training and other events: June 2019-July 2019

Please find below a table of all upcoming XM² training and other events from June 2019 until July 2019 as far as planning currently allows and subject to change. Please note that some locations and events have been updated and added since the previous month’s table.

PGRs, please highlight any XM²-training related absence times to your supervisors. In regards to annual leave or other absence time planning: All confirmed events have been sent to the PGRs via a calendar invitation, but please ensure to check the CDT in Metamaterials Outlook calendar and to liaise with your supervisors and the CDT in Metamaterials office () for approval BEFORE you make any bookings, as there might be a few more events coming up that are yet to be confirmed.

Supervisors, please be mindful of the XM² events when setting expectations on research deliverables with the PGRs.

Pint of Science Festival 2019

Last month Pint of Science returned to Exeter. Pint of Science is a worldwide science festival that takes place every year and brings researchers to your local pub to present their scientific discoveries. This year it was in over 24 countries in nearly 400 cities. In the UK there were over 600 events in 41 cities.

This year in Exeter, there were four main themes: Our bodies (Exonian), Our beautiful minds (RAMM), Planet Earth (Henry’s Bar) and Atoms to Galaxies (City Gate). Over 550 tickets were sold across the festival.

The Atoms to Galaxies Team was the Physics/Engineering topics. It was held at the City Gate. We had 3 events: “Little Things Make A Big Difference”, “Tech That, Tomorrow” and “Stars, Planets and Disks”. Each night there were three talks given by active researchers, interactive sessions and a quiz with questions based on the theme of the night. Over the three nights we sold over 110 tickets (116) with the “Little Things Make A Big Difference” and “Tech That, Tomorrow” events being sold out.

The below groups included CDT students (indicated in brackets) and University staff:

Emily Glover was also involved with publicity of Exeter’s Pint of Science in general.

 

The events were covered by university student media and two of Exeter’s Pint of Science leaders, Aaron Labdon and Anastasiia Kovalenko, spoke about the various themes on BBC Radio Devon.

As you can see from the photos below, the audience were engaged with plenty of talks and activities.

PGRs Emily Glover and Vicky Kyrimi at Phononics 2019

Second-year PGR Emily Glover and fourth-year PGR Vicky Kyrimi presented at Phononics 2019– a biannual conference series that started in 2011. This year’s conference ran from 3rd to 7th June, and was held in Tucson, Arizona.

Emily presented a poster, entitled ‘Tunable Magnetoelastic Phononic Crystals’, and Vicky presented a talk on  ‘A Metasurface comprising Spiral shaped Local Resonators for Surface Acoustic Waves’. This is what Emily said of her experience:

The conference was my first experience presenting my research internationally, and was a great opportunity to meet and learn from some of the top professors in the Phononics community. The conference included a half-day excursion to visit the local desert museum, to learn more about Tucson and the famous Saguaro cactus that can only be found in Arizona, as well as a session for early career researchers about networking skills.

Vicky said of her experience:

I’m happy to mention that the work I presented at this conference was accepted for publication. I attended the conference banquet which was a great opportunity for networking with people in my field.

See below for photos from the event.

Kishan Menghrajani presents at Leibniz Institute of Photonics Technology

At this year’s Molecular Plasmonics conference at Leibniz Institute of Photonics Technology, Jena, fourth year PGR Kishan Menghrajani presented his work on ‘Molecular vibrational strong coupling in a metal-clad microcavity below cut-off‘ .

The meeting, held from 23rd to 25th May,  was focused on bioanalytical and nanophotonic applications of plasmonic effects at nanoscale metal structures, utilizing the phenomenon of localized surface plasmon resonance (LSPR). This included e.g. phenomenon occuring at molecular components due to local field enhancement effects, interactions with fluorescent dyes, sub-wavelength apertures as well as comparisons of simulations with experimental results. Also effects based on electron release and subsequent processes like catalyses was discussed.
