trying to see little things happening quickly

I have funding for at least one (hopefully more!) PhD projects starting next October - If you know anyone who might be interested, please share it with them! Thank you 🙏 https://t.co/4apBZJkxSH.

A paper on metal halide perovskites from time in @Huber_Group and in Oxford, just published in Nature Photonics

We use ultrafast nanoscopy to see structural modes on the nanoscale as well as ultrafast charge carrier motion!

@MarcelRighet Thank you for your kind words Dr Righetto

Nature research paper: All-optical subcycle microscopy on atomic length scales https://t.co/QD1Dt606Gg

[Tom Siday @tomsiday]

As well, we wrote a little briefing which gives a bit of an overview!

Some work from my time in Regensburg, in the @Huber_Group.

We worked out how to measure the coherent emission from tunnelling electrons, this lets us do ultrafast optical microscopy now at the atomic scale!

Beautiful new work from friends in Regensburg @Huber_Group, who were able to see - in a single defect! - how ultrafast atomic motion shifts energy levels.

The Aharanov-Bohm effect

Weisskopf said: The first reaction to this work is that it is wrong; the second is that it is obvious

Ehrenberg said: Ach Hiley, zis AB effect that you are discussing, is it the one that Siday and I discovered?

What is it?

Are you working on new semiconductors for solar energy applications? Chip in with an oral abstract for our #NextGenSolar symposium at MATSUS-24 in sunny Barcelona. Deadline for oral presentations on Wednesday 22nd, submit now! 👇

@MarcelRighet @GroupHerz I've been waiting all day for this! I'll get started alloying them now. thanks Dr Righetto!

🔬Our work on AgBiS2 NCs is out! Disorder, often considered as a detrimental, turns into an asset when controlled. We show how cation-disorder engineering surprisingly boosts charge-carrier transport. https://t.co/q56H1idMZL

[Huber Group @Huber_Group]

We observed the ultrafast emergence of a Floquet-Bloch band structure for the first time. Strong-field #ARPES revealed that Floquet-Bloch states form already after a single optical cycle.

The results have been published in @Nature:

Highly recommended!

[Huber Group @Huber_Group]

Together with @UMengineering, we realized a stopwatch for delocalized Bloch electrons in crystals that achieves attosecond precision. This way, many-body correlations can be directly measured.

Our results were published in @Nature.

The latest issue of Nano Letters is live! On the cover: "Ultrafast Nanoscopy of High-Density Exciton Phases in WSe2" @Huber_Group @MalicGroup  

Learn more: https://t.co/gsF8wY16x7

[Huber Group @Huber_Group]

In collaboration with @MalicGroup, we used ultrafast near-field microscopy to study the Mott transition of strongly-bound excitons in an atomically thin heterostructure of WSe₂.
