Hey #compchem, simulating nuclear wavepackets? We've got a protocol for you so you can excite them with entangled photons: pubs.acs.org/doi/10.1021/ac… All credits to @BingGu8 !

Entangled photons for photochemistry? A simulation study on everyone's favourite photoswitch, #azobenzene : pnas.org/content/118/47…

@laura_mccaslin @SandiaLabs Quantum Control is exciting! Good luck with finding a suitable candidate, looking forward to hearing more about your research in this direction.

News from our Spectroscopy-of-Conical-Intersections-Department: Use non-invasive resonant infrared fields to enhance the coherence! Out now @J_A_C_S pubs.acs.org/doi/10.1021/ja…

@james29892 Very interesting paper, thanks for sharing (and congratulations)!

Now out in JCTC! An approach to study the quantum dynamics of multi-chromophore systems, using the guanine-cytosine DNA base pair as an example. Here's a quick video overview of the method and results. Read the article here: doi.org/10.1021/acs.jc… #compchem #scicomm

We are happy to announce that the registration for the 57th Symposium on Theoretical Chemistry is now open! Virtual conference, organizers located in Würzburg, Germany. Follow us for the latest updates and highlights. #compchem

Excited state dynamics of cyclooctatetraene: doi.org/10.1021/acs.jp… The photochemistry involves a dynamical interplay of aromatic and non-aromatic states, mediated by conical intersections. Another nice collaboration between LANL, UCI and UNIBO!

TRVS 2021 Conference is starting in a couple of hours: trvs2021.org Stacked program, many interesting talks this week. Come meet me at my (online) poster, I'll be discussing a recent paper doi.org/10.1103/PhysRe… (and other ones if there's interest)

@SpecTqd @d__jadoun @eric_davidsson Beautiful signal. And even an experimental one!

Already looking forward to it!

A discussion you can learn a lot from about the current and future approaches in ultrafast X-ray science: doi.org/10.1039/D1FD90… Very good read!

@AGTheoChem Gut gelungene und informative Ausgabe!

Quantum optimal control for spectroscopy: doi.org/10.1103/PhysRe… Optimize the pump to selectively enhance the probe! This can enable the detection of interesting, but inherently weak spectral signatures.

Returning to campus/office after more than one year of home-office. Feels a lot like visiting your childhood neighborhood again after many years. The flashbacks are real!

@Bach_Lab @UCIChemistry @FabianHoermann Good luck! If you need help from an experienced Munich-to-Irvine-transitioner, let me know.

Recently graduated, now post-doctoral fellow in the group of Chris Vanderwal @UCIChemistry. We wish Fabi (@FabianHoermann) all the best for his research stay in #SoCal! #bach_lab #chemtwitter

Researchers from SLAC, @UW and @PNNLab used X-rays from #LCLS to capture the rapid motions of solvent molecules that impact light-driven reactions in a molecular complex. What they learned could aid the development of more efficient clean energy sources. stanford.io/2PYmftX

Live-streaming is really taking over, not even space can stop it. @NASA is currently streaming live from the International Space Station! This is so fascinating.

Yet another reason why X-ray TRUECARS is so powerful in detecting molecular coherences: It even works in organic chromophores (>100 Atoms) with photovoltaic merit, where decoherence is a serious obstacle. Check it out: doi.org/10.1039/D0SC06… #compchem @vmfreixas @sfalberti
