Vibronic and Spin–Orbit Interplay Governs Ultrafast Spin Crossover in an Iron(II) Carbene Complex (Ajay Jha and co-workers) @Ajay_RFI#ChemPhysChem
https://t.co/94HpB8TxXQ
Our work on ultrafast spin crossover in iron(II) carbene complexes is now published. Using ab initio methods and HEOM simulations, we explore how vibronic and spin-orbit interactions govern excited-state dynamics and lifetimes.

Fully intragroup, great learning curve. Synthesis of several parallel ideas. Heroic efforts by Asha, Vivek, Camelia, and Indranil, made only possible by help from Vivek Bhat & Sayan. Big thanks @ANRFIndia for funding. Summary below.

@CankayKoryak I can see. The TOC figure may visually resemble a lattice model, but it does not represent the Hubbard model in a physical or theoretical sense.

@CankayKoryak We have investigated quantum coherences in photosynthetic systems, and our work, along with others in this field, is summarised in our latest review:

This is a quietly important result.
What’s being shown here is not just long-lived vibronic coherence, but phase information persisting across intersystem crossing, a process traditionally treated as fully decohering and stochastic.
The implication is subtle but profound: excited-state dynamics are not simply governed by rates and populations. Geometry and coupling constrain the flow of phase, allowing coherence to participate in the dynamics rather than being erased by them.
As more experiments point this way, it becomes harder to maintain the view that coherence is a fragile by-product. Instead, it begins to look like an emergent consequence of structured energy landscapes, where form guides dynamics, not noise.
A careful step forward, but one that quietly reframes how we think about excited states.

@ghoshata96@J_A_C_S@RosFrankInst@SLAClab@CLF_STFC@UniofOxford Thank you Atanu. I have read your seminal papers with Jim on Co(III) complexes and found them truly inspiring. They have been a strong motivation for my exploration of these d-d transitions 😊
