Many thanks to Bipasa Samanta, the postdoc in our group, who performed the calculations and taught me about the connection between bond angles in perovskites and conjugation in organic molecules, and to Ricardo for inviting us to this collaboration.

New work with my postdoc Bipasa Samanta on superconducting nickelates. After showing a remarkably strong correlation between in-plane Ni-O-Ni bond angles and Tc in La3Ni2O7, we investigate the effects of other factors (strain, correlations, layer number) on the likely Tc. arxiv.org/abs/2506.11427

We congratulate Varsha Kumari for winning a teaching award. She did a wonderful job teaching with me Intro to physical chemistry and the Surface Chemistry class. In one evaluation, a student answered the question 'How can she improve?' by saying 'Nothing. She's doing amazing'.

Alexandru B. Georgescu @alexandrubg.bsky.social · 31/05/2025

Awesome job Varsha Kumari and Bipasa Samanta presenting your work with a talk on trimer formation in Kagome materials and a poster on superconducting nickelates at the Midwest theoretical chemistry conference in Detroit!

New work led by our excellent PhD student Varsha Kumari (with early contributions from Julia Bauer, now at Yale): we show that triangular cluster formation in Kagome multiferroics is driven by trimer orbital symmetry & intermediate correlation strength. arXiv: arxiv.org/abs/2505.13659

Happy to have contributed to this complex collaborative work - now in PRX - showing that infinite layer nickelate superconductors may be more different from cuprates than we thought: they may be superconducting even in the absence of doping: journals.aps.org/prx/abstract...

journals.aps.org

Superconductivity in the Parent Infinite-Layer Nickelate ${\mathrm{NdNiO}}_{2}$

Undoped NdNiO${}_{2}$ exhibits superconductivity up to 11 K, challenging the assumption that doping is essential in layered nickelate superconductors.

Congratulations to our student Emily Ward, who graduated with the highest award from the department, and pursued both theory and experiment as an undergraduate student. Her curiosity, drive, and kindness will be missed. We wish her good luck during her Phd at Princeton!

Last day of volunteering at IU Care Week. It was maybe as helpful for me as it was for the students: I could feel helpful without handing out work/assignments/grades. Just bagels and cream cheese, no added pressure or stress on anybody. And if you know me you know I love feeding people 😬😂.

Alexandru B. Georgescu @alexandrubg.bsky.social · 01/05/2025

Lived my dream of running a food cart at IU Care Week, serving students breakfast. Downside: my dream is not for me. My wrists are weak and hands are shaky.

Last year some finches built their next close to my feeders, on top of a wall. This week the old nest fell on the ground. What I didn't see last year was that the finches also used the cotton I left them for the nest! It looks like it must have been pretty comfortable.

In work now in ACS Nano, we showed how magnetic order propagates in a complex system: double perovskite superlattices! Amazing experimental work by Jonathan Spring and Marta Gibert who invited me to work on this; I just wrote some scripts in Matlab: pubs.acs.org/doi/10.1021/...

In our new collaborative work, now in JACS, we find surprisingly high magnetic exchange (up to 340K!) within Cr S=1/2 spin chains in both experiment and DFT - even though the Cr ions are 6.6A apart. Despite this, there is no magnetic order down to 0.1K. pubs.acs.org/doi/full/10....
