Graphene flakes, strange metals, and black holes: insights from the SYK model
Subir Sachdev

Complex many-particle quantum entanglement is a central theme in two major
topics in physics: the strange metal state found in numerous correlated
electron compounds, and the quantum theory of black holes in Einstein
gravity. The Sachdev-Ye-Kitaev model provides a solvable theory of
entangled many-particle quantum states without quasiparticle excitations.
I will describe how the SYK model sheds light on recent experiments on
graphene flakes, has led to a universal theory of strange metals, and
provides new insights on the quantum states of black holes.
