Hi everyone :-D
We have reached the weekend already. Over the last few days, I hope I managed to give you a small glimpse into my research field. But one promise I have not yet delivered on: Where will all of this lead? What's the point?

First of all, I don't think I have to convince you that the quantum tunnelling phenomenon is found in all kinds of fields. Recently I came across a paper discussing tunnelling times during a photosynthesis cycle in an organic molecule.

Many might be familiar with Scanning Tunnelling Microscope (STM) technique to investigate surface structures with (sub-)atomic spatial resolution (or make an atomic stop-motion movie 😄)
It is evening again, and I finally find a moment to check in here. How are you doing?
I feel like my apartment has turned into a bit of a "sauna for beginners": higher room temperature than I would usually keep in wintertime, and more humid than usual in general (despite having open windows)...
I'm going to switch my plan around a bit. The exciting opportunities for future scientific and technological developments derived from #attoscience (and if I find the time, a project using nano-objects to modify the spatial dependence of my laser fields) will come later.
Hello everyone!
To talk about my research, I decided to theme it by "studying the ionisation process itself" (today) and "possible things that can happen afterwards" (tomorrow).

I'm going to keep the explanations in the threads fairly colloquial. But I will link the corresponding publications (open access whenever possible) so you can dig into the details there if you wish. Or of course, just ask me any questions you might have and I'll expand on that 😉
Yesterday I have already introduced the idea that the strong electric field of the laser pulse modifies the Coulomb potential which keeps electrons in bound states. The video shows a classical picture of this:
Dear all, today I (@carlafmfaria) will take over, talk about myself & what I have learned on the way. I am a professor of physics at @UCL working on #attoscience, was born in the Amazon, & I am as mixed as it gets (ca 10 ethnic groups). Hope you enjoy it. Thread will come slowly
1) For those who don't know me, I am also an undercover Black Prof, lumped under “mixed other”. This has to do with not willing to wipe out mom’s Indigenous ancestry with a pen stroke. HR forms reflect British colonization and but my country was invaded by the Portuguese.
2) Being a pardo (Black person of Afro-European phenotype) is not a big deal in the Amazon, b/c we are 70% of the population (German husband is an attraction at the beach). My paleness puts me on top of the racial hierarchy, which shows you that race is a social construct.
