The Swampland program aims to distinguish effective theories which can be completed into
quantum gravity in the ultraviolet from those which cannot. This article forms an introduction …

These lectures give an introduction to the quantum physics of black holes, including recent
developments based on quantum information theory such as the firewall paradox and its …

Among Swampland conditions, the distance conjecture characterizes the geometry of scalar
fields and the de Sitter conjecture constrains allowed potentials on it. We point out a …

A bstract A quantum extremal island suggests that a region of spacetime is encoded in the
quantum state of another system, like the encoding of the black hole interior in Hawking …

A bstract In the Emergence Proposal in Quantum Gravity it is conjectured that all light-
particle kinetic terms are absent in the fundamental ultraviolet theory and are generated by …

We construct an infinite family of microstates with geometric interiors for eternal black holes
in general relativity with a negative cosmological constant in any dimension. Wormholes in …

A bstract After turning on an interaction that couples the two boundaries of an eternal BTZ
black hole, we find a quantum matter stress tensor with negative average null energy, whose …

A bstract The Swampland Distance Conjecture (SDC) states that, as we move towards an
infinite distance point in moduli space, a tower of states becomes exponentially light with the …

This is the written version of a lecture given at KITP in Oct 2014 on Black Holes and quantum
complexity. I've included (in boldface) various questions that came up during the lecture and …

We discuss aspects of global and gauged symmetries in quantum field theory and quantum
gravity, focusing on discrete gauge symmetries. An effective Lagrangian description of Z p …
