Quenches and lattice simulators for particle creation
Francesco Caravelli, Fotini Markopoulou, Arnau Riera +1
In this paper we propose a framework for simulating thermal particle production in condensed matter systems. The procedure we describe can be realized by means of a quantum quench…
The Computing Spacetime
Fotini Markopoulou
The idea that the Universe is a program in a giant quantum computer is both fascinating and suffers from various problems. Nonetheless, it can provide a unified picture of physics…
Disordered locality and Lorentz dispersion relations: an explicit model of quantum foam
Francesco Caravelli, Fotini Markopoulou
Using the framework of Quantum Graphity, we construct an explicit model of a quantum foam, a quantum spacetime with spatial non-local links. The states depend on two parameters: th…
Trapped surfaces and emergent curved space in the Bose-Hubbard model
Francesco Caravelli, Alioscia Hamma, Fotini Markopoulou +1
A Bose-Hubbard model on a dynamical lattice was introduced in previous work as a spin system analogue of emergent geometry and gravity. Graphs with regions of high connectivity in…
Background independent condensed matter models for quantum gravity
Alioscia Hamma, Fotini Markopoulou
A number of recent proposals for a quantum theory of gravity are based on the idea that spacetime geometry and gravity are derivative concepts and only apply at an approximate leve…
Properties of Quantum Graphity at Low Temperature
Francesco Caravelli, Fotini Markopoulou
We present a mapping of dynamical graphs and, in particular, the graphs used in the Quantum Graphity models for emergent geometry, into an Ising hamiltonian on the line graph of a…
