Sad, I rejoined today to try to find people. Is there any other place that’s more active?

And yes, I brought my daughter, and yes we are trolling for invites to dinners and receptions. She’s a very good guest, provided I bring my phone and Minnie Mouse YouTube.

I will be giving two talks on *new* science. One focused on designing j-aggregates (out soon in JACS pending final ok) and one talk on HgTe quantum dots, and why they are basically the best material of all time.

Still Not Feeling the Same After COVID-19? You’re Not Alone

Men's testosterone levels declined in last 20 years
A new study has found a "substantial" drop in U.S. men's testosterone levels since the 1980s, but the reasons for the decline remain unclear. This trend also does not appear to be related to age.

This ‘deceptively simple’ question demands a dip into the murky waters of quantum physics.

I am left to ask, what’s the point of capitulating to people who despise you? I’m not here to just produce science points like some kind of perverse sims game.

Or systems that are pathologically protected (e.g. nv center in diamond)

jrcaram.bsky.social @jrcaram.bsky.social · 27/12/2024
I wish this is how molecular photophysics worked. But alas, relaxation is really fast in the condensed phase. Very few coherent processes survive. The rare cases that coherence matters are when processes are also fast (energy transfer), or somehow the coherence is protected (e.g. triplets).

jrcaram.bsky.social @jrcaram.bsky.social · 27/12/2024
To elaborate, there is a vibronic shoulder at ~1000 cm-1, 33 fs period. Relaxation time scale is probably about 300 fs (generously). so 9 ish periods. Is that the mechanism of action? Alternative explanations could be lower QY (and more thermal radiation) exciting the shoulder as well.

jrcaram.bsky.social @jrcaram.bsky.social · 27/12/2024
I may have missed it, but I see no conclusive proof here that it isnt just excess thermal energy by exciting at a specific band.
100
jrcaram.bsky.social @jrcaram.bsky.social · 27/12/2024
Ok, I read the paper, and I am not convinced. Yes the excited a vibrational shoulder, and that vibration is "coherent" but going by the width of the vibrational shoulder, and standare relaxation times probably only over like 5 periods (as someone who has extensively studied this).

I'll be recruiting postdoc(s) to start from July 2025 onwards at UCLA. Potential projects are very flexible, and can be tailored to your interests, but will be broadly in the area of quantum dynamics of chemical systems.

A few years ago, Mercouri Kanatzidis mentioned that he had observed PbS was somewhat ferroelectric at low temps, similar to some of his later work on perovskites. Nice to see how symmetry and size plays into these NC dynamics.
