We theoretically study 2D optical spectra cross peaks arising from indirect, bath-mediated interact described by quantum cross-correlation functions. pubs.aip.org/aip/jcp/article… Our paper is selected as a J. of Chem. Phys. "Editor's Pick"! @ScienceNTU

Spent several delightful days at IISER Mohali, attending the UNOOS conference organized by @arijitb4u, & celebrating Debu Goswami's 60th birthday. Made new friends and learnt new stuff.

Can crosspeaks appear in a 2D spectra of a dimer system without direct coupling or population transfer between the two monomers? Yes, a different type of crosspeak appears if we have a quantum time cross correlation function between them. pubs.acs.org/doi/10.1021/acs…

Hiked up Ben Nevis, UK's highpoint at 1345m, with Taka Tanimura, Klaas Wynne and his son Guus. This is a Summit Summit event where we meet to climb a mountain (usually a country highpoint), and discuss science. (Ok, the latter is usually the excuse for the former :p)

Conference ends at CMDS2024 @cmds_online in York. Wonderful science and fellowship. Superb organization by the team led by Neil Hunt. CMDS2026 will be in Singapore. (Can't really say I am looking forward to it.. since yours truly will be the one trying to organize it).

Attending the Coherent MultiDimensional Spectroscopy conference (CMDS2024) at York. Some of our group members' presentations. @cmds_online

CMDS 2024 begins with a lecture on the history of York, England, by the chair of the conference, Neil Hunt. @cmds_online

We measure the Ultrafast Energy Transfer between FCP light harvesting complexes and the Photosystem II core complex in diatom photosynthesis. A collaboration with @PHLambrev and others. pubs.acs.org/doi/10.1021/acs…

Exposed to iron limitations, some cyanobacteria produce iron stress-induced protein A (IsiA) pigment-protein cplxs, which assemble around Photosystem I (PSI). We measure a very fast ~3ps energy transfer from that IsiA to PSI core w/ 2DES. @PHLambrev frontiersin.org/journals/pla…

How fast is energy transferred from the light harvesting antennae to the Photosystem II core in photosynthesis? We directly measured this process in our Sci. Adv. paper. @ScienceNTU. Great work @Long26598564 & collab w/ @PHLambrev @parvidua @cour_lab science.org/doi/10.1126/scia…

Meeting up with old friends. Yoshitaka Tanimura and Maxim Gelin. Having some spicy Singapore Katong Laksa.

We derive the equations and explain how the time dependent behavior of a crosspeak in a 2D spectrum tells us about the correlation and fluctuation dynamics between transitions in a multistate system. pubs.acs.org/doi/10.1021/acs…

Excited to participate in my very first @GordonConf. Gave a talk on our work 'Measuring the antenna to core inter-complex energy transfer dynamics in plant Photosystem II'.

Our most recent published work. w/ LUMINOUS!NTU, @oprezhdo etc...: Measuring the Ultrafast Spectral Diffusion and Vibronic Coupling Dynamics in CdSe Colloidal Quantum Wells using Two-Dimensional Electronic Spectroscopy pubs.acs.org/doi/10.1021/acs…

NISE watching @lacour_c giving his talk at #CMDS2022 @cmds_online
