"Gauge Choices, Infrared Pitfalls, and Thermal Effects in Effective Potentials" Now, resummation ensures IR-safety irrespective of gauge choice. For the first time, we compute gauge inv eff-potential upto all orders in m/T in finite temp. arxiv.org/abs/2507.22706

Calendar for the call of proposals by @ANRFIndia for the year 2026

A fantastic paper by Sabyasachi and his students: "Axion EFT in the BMHV Scheme: Flavor Currents, Evanescent Operators and Ward Identities" arxiv.org/abs/2603.26880

Huge thanks for the support for the Prof. Rohini Godbole Memorial Fund so far! 🙏 We’re making great progress but still need your help to fund our very first RMG Fellow at CHEP. 🔬✨ Join us in supporting women in science: chep.iisc.ac.in/prgmef/ #WomenInScience #IISc

@dwarkesh_sp I’m sure somebody has pointed this out somewhere. But this, more or less, exactly matches Feynman’s feelings on the IAS

@modularform @_bos_on Great Let me check if i can do that

@jd_iitk @_bos_on The teaching can be offline. You just write on a tablet instead of the blackboard. The recording is for you and not the students. So no links need to be shared with them. Get permission from your department for this.

Next semester at IIT Kanpur, I am offering a full course on Effective Field theory, which consists of 36+ lectures.

@modularform @_bos_on Here we have to teach offline and that too on board as per instructions

@jd_iitk @_bos_on Write on a tablet and share your screen via Google meet/Zoom and record it there. It gives reasonable quality. I did this during Covid and my Classical Mech and Stat Mech lectures are on my YouTube channel. Take a look and see if that works for you.

@entanglednomad QFT 1, 2, and advanced mathematics. Aim for advanced PhD students only.

@jd_iitk Sir,Will it be too hard for ug students? And what's prerequisites?

Here is the outline of the EFT course:

@Kaju_Nut @TradeTexasBig Those are mostly for the popular courses. EFT is not one of them :(

@TradeTexasBig @jd_iitk There are nptel courses everyone can sit in.

@Chandra06891946 yes notes and videos as well (if recorded)

@jd_iitk Great! Will you make your notes public ?

@TradeTexasBig @Kaju_Nut Not sure about this.

@Kaju_Nut @jd_iitk Shouldn't all iit networks be connected allowing anyone to attend or audit ?

@TradeTexasBig Will try to record and then put on YouTube or so. let's see.

@jd_iitk Post notes or lectures online?

@_bos_on I am planning to record it. let's see if technology permits :)

@jd_iitk would it be recorded?

I am delighted to share that I will serve as the Founding Director of the Lodha Theoretical Physics Institute (LTPI), Mumbai. ltpi.org Launching with EPQHS-10 (May 27–29, 2026), LTPI aims to become a world-class centre for fundamental physics. ltpi.org/epqhs10-meeting Grateful to the Lodha Foundation, Abhishek Lodha, and Penn State for their support and making . A deeply meaningful personal milestone for me.  An opportunity to contribute to India’s scientific future represents a dream realised.

We have strengthened our HEP group @IITKanpur @IITKphysics with the joining of our new faculty colleague, Dr. Goutam Das, who is an expert in perturbative QCD, SCET, etc.

@Physicla_ Congratulations!

#one_big_milestone 🥳

I have a post-doctoral opening in my group. If you are working in one of the following areas: Galaxy Formation, Science with the 21cm line, Gravitation Lensing, then please drop a message.
