Our latest work on comparing the IR behavior of no-boundary and dS wave function at one loop. After a heavy computation the leading behavior is seen to be same. Work is however technically involved. https://t.co/J0Od6TPMzL

I am delighted to share that I will serve as the Founding Director of the Lodha Theoretical Physics Institute (LTPI), Mumbai. https://t.co/CgvGNCSaKx

Launching with EPQHS-10 (May 27–29, 2026), LTPI aims to become a world-class centre for fundamental physics. https://t.co/Ffh9EwckvZ

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.

Please apply for PhD positions under the National Quantum Mission (NQM) in our group. We have multiple opportunities for students to work on cold atom quantum memory and quantum network. We are also interested to host students to work with us on portable atomic clock development.

Chinese President Jiang Zemin Taught Limits Using Zhuangzi’s One-Foot Rod.

In November 2001, then Chinese President Jiang Zemin visited Beijing University of Technology.

During an impromptu stop in a calculus class discussing derivatives, he picked up chalk and wrote on the blackboard: Zhuangzi said: "A one-foot hammer (or rod), take half of it each day, and it will never be exhausted through eternity." (一尺之棰，日取其半，万世不竭。)

He then wrote a mathematical formula to precisely capture its meaning, explaining: "This is our ancestors' extremely important idea of limits."

This ancient paradox from Zhuangzi's "Tianxia" chapter beautifully illustrates the concept of infinite division and the limit approaching zero — a profound insight predating modern calculus by over two millennia.
