New paper out today!

This time with Chris, we study the defect entanglement entropy for superconformal RG interfaces. These are susy codimension one interfaces separating the SCFT LS and the N=4 SYM with spatially varying mass terms.

New paper out today: We study scale-invariant hydrodynamics and show, among other things, that hydrodynamics—despite being an effective framework—is strongly biased toward conformality.

@garellaprachi @karch_andreas Thanks Prachi!

Paper today! This time with Ignacio, Carlos and @karch_andreas we showed that the boundary entropy and effective central charge are connected, as well as non-interface crossing intervals pick up a boundary contribution: https://t.co/NqqmK5HqRT

New paper out: this time we formulate fracton gauge theories in curved spacetimes: https://t.co/KvUeMvV4gm !

[Evangelos Afxonidis @conifold]

In our paper, we explored the boundary entropy function and derived a g-theorem for it. Many thanks to @karch_andreas for the collaboration!

Since we are at it (and since @conifold just liked my last paper post -- great twitter handle!): here from last December. Evangelos was visiting for 3 months and got a nice paper out from it!

@erisaonX Yeah, like having access to counselling services within the institution would def help or training the fac to recognise signs of mental issues. In Greece/Spain in most institutions these options def don’t exist.

The podcast with Dr. Fernando Quevedo has been uploaded. Among other things, we talk in detail about his recent paper with @CburgesCliff on getting deSitter in string theory. Go watch!

I wrote some lecture notes on an introduction to generalized global symmetries:

I've always felt that these ideas could basically be taught at the level of an intermediate QFT course. This is my attempt at doing so!
