Condensed Matter Physics and the Nature of Spacetime
 

Summary: CHAPTER

Condensed Matter Physics and the
Nature of Spacetime
Jonathan Bain*
Abstract This essay considers the prospects of modeling spacetime as a phenom-
enon that emerges in the low-energy limit of a quantum liquid. It evaluates
three examples of spacetime analogues in condensed matter systems that
have appeared in the recent physics literature, indicating the extent to
which they are viable, and considers what they suggest about the nature
of spacetime.
1. INTRODUCTION
In the philosophy of spacetime literature not much attention has been given to
concepts of spacetime arising from condensed matter physics. This essay attempts
to address this. It looks at analogies between spacetime and a quantum liquid
that have arisen from effective field theoretical approaches to highly correlated
many-body quantum systems. Such approaches have suggested to some authors
that spacetime can be modeled as a phenomenon that emerges in the low-energy
limit of a quantum liquid with its contents (matter and force fields) described
by effective field theories (EFTs) of the low-energy excitations of this liquid. In
