STOP WAR. Doing science and photography. Keen on Optical and acoustic forces, and angular momenta. 🇦🇺🇷🇺🇯🇵

For academics. I created a web interface for latexdiff. It also shows how figures have changed. I hope it is going to be helpful for the others, e.g. during the revision stage.

Pretty unexpected work for me, it was completely a side project with a wonderful student Rickson Wielian at @ANU_Research. But turned out to be quite interesting paper, we figured out T-matrix formalism for topology of the edge states

Our recent paper in Phys. Rev. Appl. on "acoustic lift" effect with resonant scatterers: anisotropic particle may stably drift in the acoustic wave. Its an acoustic sindewinder sailboat but with sound!
A highlight from APS below

Manipulating light with a twist, for working with chiral molecules, eg asymmetric drugs, gets heaps easier thanks to neat insight. No complicated components, use simple ones arranged asymmetrically

If you have ever submitted to @PhysRevLett you know that it can be very time consuming to find all the refs in SM but not in the main text. There is a script to do it automatically! Hope it will helpful to somebody.

I’ve an immediate vacancy for a postdoc or staff scientist on a project related to integration of NV diamond with WGM resonators. Only suitable for experimentalists with lots of optics experience. Come live on beautiful and peaceful Okinawa in the fabulous @OISTedu

For the most recent video, I had way too much fun simulating the electric field (or rather, the component of that field responsible for radiation) and how it responds to an accelerating electric charge.

[KOALA Conference 2024 @KOALAConference]

We are thrilled to announce that #KOALA2023 will be held at the Research School of Physics, #ANU in Canberra. The organising committee have been hard at work planning an exciting program. Follow our website (https://t.co/5K9cYqM3Gd) for more information. See in you November!

My favourite project so far! Second harmonic field may carry angular momentum which might not be compensated. This leads to the spinning torque according to conservation laws.
It can be dominant effect for the transparent particles with axial symmetry!

Fundamentals, advances and perspectives of optical manipulations using metamaterials are now explicitly presented. Two typical implementations are reviewed, i.e., meta-tweezers and meta-robots. @yuzhi_shi @ivan_toftul https://t.co/S4zrO5pt9O

@JodieBradby @PhysicsANU Wow, thanks! 🙏

[Ivan Toftul @ivan_toftul]

@Sarah_Barr It's not that bad. Imagine nobody knows about tables. Then peer review might reveal not obvious things to other people. You just add a paragraph that shows "the optimal stability is achieved with 4 legs and 5th leg does not really improve the situation", etc

@SileNicChormaic 😍

[Ivan Toftul @ivan_toftul]

Welcome our review paper on Optical Forces in APR! ⚡️
I believe it might be a nice cheatsheet for those who are new to the field. Another part of the review is devoted to the question how metasurface might help tune optical forces in numerous applications.

@mathladyhazel Spin orbit interaction 🤔 each ball has only a spinning motion, but the whole thing has an orbital momentum

[Ivan Toftul @ivan_toftul]

Can we all just use SI units? Please
