8.5 Part 3: String theory and (other) science fiction
Chetan begins by reviewing the eikonal approximation, and factorization theorems for amplitudes. Amartya then discusses this in context of quantum gravity, causality constraints an...
8.5 Part 2
Santhosh begins this episode with a discussion about transverse field Ising chains and dualities, anyon algebras, and systems with known spectra but unknown states. Amartya then ta...
8.5 Part 1: Impromptu over chai
We reunite in person after nearly 2 years. Chetan begins this episode with a discussion about Witten's recent work on the deep connection between gauge-gravity amplitudes and geome...
Positivity bounds and gravity
In this episode, we begin by reviewing the weak gravity conjecture. We then discuss such "swampland conjectures" from the EFT perspective- in the form of positivity bounds, and dis...
CPT and the neutrino story
In this episode, we discuss aspects of hermiticity and unitarity, in the context of PT-symmetric Hamiltonians. Then, we take a detour towards discussing the fascinating story of ne...
Thoughts on Academia
In this episode, we discuss what has our experience doing physics been so far-how it's different from what we thought it'd be, what lies ahead. We express (some very strongly) our ...
2D magnetism with Rohan Maniar
In this episode, our friend and today's guest on the podcast, Rohan Maniar, talks about his area of research- 2D magnetic systems. We discuss long-range order in 2D systems and the...
"Chai pe charcha"
We start by briefly discussing axions and inflation. Amartya then rambles about the structure of vacua in compactified theories. Chetan discusses an interesting relationship betwee...
Integrability
In this episode, we discuss ideas of integrability in physics, ranging from classical mechanics to classical and quantum field theories. Amartya discusses some ideas about positivi...
From Parafermions to the Swampland
In this episode, Santhosh describes some features of 1D interacting systems, exploring Bethe ansatz, parafermions, dualities, etc. and Amartya rambles about unitarity bounds, 'ghos...
Cosmological collider physics
In this episode, Amartya rambles about an interesting idea of studying inflationary correlators, and we discuss the unreasonable effectiveness of physics in math....
An operator for time?
In this episode, we discuss the consequences of having a "time" operator in physical theories and ramble about related ideas....
