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 …

Artificial intelligence (AI) is gaining strength, and materials science can both contribute to
and profit from it. In a simultaneous progress race, new materials, systems, and processes …

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 …

Can we trust our senses to tell us the truth? Challenging leading scientific theories that claim
that our senses report back objective reality, cognitive scientist Donald Hoffman argues that …

We conjecture that the quantum complexity of a holographic state is dual to the action of a
certain spacetime region that we call a Wheeler-DeWitt patch. We illustrate and test the …

Recent theoretical progress indicates that spacetime and gravity emerge together from the
entanglement structure of an underlying microscopic theory. These ideas are best …

Our earlier paper “Complexity Equals Action” conjectured that the quantum computational
complexity of a holographic state is given by the classical action of a region in the bulk (the …

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 …

Starting from first principles and general assumptions we present a heuristic argument that
shows that Newton's law of gravitation naturally arises in a theory in which space emerges …
