1. Instabilities of thin black rings: closing the gap / Armas, Jay ; Parisini, Enrico
We initiate the study of dynamical instabilities of higher-dimensional black holes using the blackfold approach, focusing on asymptotically flat boosted black strings and singly-spinning black rings in D ≥ 5. [...]

2. Magnetohydrodynamics as Superfluidity / Armas, Jay ; Jain, Akash
We show that relativistic magnetohydrodynamics (MHD) can be recast as a novel theory of superfluidity. [...]

4. On actions for (entangling) surfaces and DCFTs / Armas, Jay ; Tarrío, Javier
The dynamics of surfaces and interfaces describe many physical systems, including fluid membranes, entanglement entropy and the coupling of defects to quantum field theories. [...]

5. Extremal black hole horizons / Armas, Jay ; Harmark, Troels ; Obers, Niels
Using the blackfold effective theory applied to extremal Kerr branes we provide evidence for the existence of new stationary extremal black hole solutions in asymptotically flat spacetime with both single and multiple disconnected horizons. [...]

6. On the surface of superfluids / Armas, Jay ; Bhattacharya, Jyotirmoy ; Jain, Akash ; Kundu, Nilay
Developing on a recent work on localized bubbles of ordinary relativistic fluids, we study the comparatively richer leading order surface physics of relativistic superfluids, coupled to an arbitrary stationary background metric and gauge field in 3 + 1 and 2 + 1 dimensions. [...]

8. Gravitational tension, spacetime pressure and black hole volume / Armas, Jay ; Obers, Niels ; Sanchioni, Marco
We study the first law of black hole thermodynamics in the presence of surrounding gravitational fields and argue that variations of these fields are naturally incorporated in the first law by defining gravitational tension or gravitational binding energy. [...]
