17. Jet energy-loss in the OO-era

As I write this, the LHC is running proton-Oxygen and Oxygen-Oxygen collisions for the first time. These experiments will give unprecedented control over small droplets of QGP that are notoriously plagued by biases in heavy-ion collisions. In the near future we will be extending our analytical studies of jet quenching in small systems, as well as producing predictions for quenching in OO using...

18. Holography, chaos, and quantum information

A quick overview of some ideas I plan to explore around holography, quantum information, and maybe a bit of machine learning.

19. Renyi refined quantum null energy condition and its holographic implications

Tanay Kibe

The quantum null energy condition (QNEC) is a quantum field theoretic realization of Landauer’s proclamation that information is physical. QNEC imposes a lower bound on the energy in a region in terms of the information contained in the complement of that region. In this talk I will describe ongoing attempts to rigorously prove a Renyi refinement of the QNEC and understand its implications on...

20. de Sitter physics via AdS/(B)CFT

Adwait Gaikwad

18/07/2025, 11:30

Expectation value of simple massive fields on a de Sitter spacetime can be computed using a) embedding of codimension one de Sitter spacetime in a Anti de-Sitter spacetime and b) the AdS/CFT dictionary. I will talk about connections of these techniques with boundary conformal field theory with a spacelike boundary

21. Integrability of open strings ending on D7 branes

Integrability of open strings ending on D7 branes is an interesting problem because one can consider two distinct embeddings, S2 ×S2 or S4. The more symmetric case has been shown to be suggestive of integrability in previous works in the gauge theory, whilst the opposite is true for the S2s. For simple solutions, analytic non-integrability techniques have been applied to both cases, but have...
