@makemytripcare I want it to be confirmed by today and have my Visa appointment tomorrow morning. I need to show them a round trip confirmed flight booking. That's why I need to change the date of flight and for that it has to be confirmed by your side. Please do it ASAP! Thank you.

A special mention to Prof. @manabsarma, who kindly took time out of his very busy schedule to meet us (with @su_dipta_ Da). We had a long discussion about research, careers, and many other things. His encouragement meant a lot. And yes, he also treated us to a great coffee!

We also visited Pobitora Wildlife Sanctuary (on Prof. Sharma’s suggestion) and later went to Guwahati city, crossing the mighty Brahmaputra River. It turned out to be an amazing trip overall.

[SUJAN MANDAL @sujan_chem]

Surreal feeling. Visited my Alma Mater IIT Guwahati again. Here’s a short thread ...

BAGH with response properties: SFX2C-LRCCSD !!
Check out our latest work where we show that scalar relativistic effects suffice for static polarizability of heavy elements, and our density-fitted LR-CCSD enables large-scale calculations.
