Lévay Péter (BME Elm. Fiz. tanszék):
A toy model of emergent spacetime and the associahedron

According to a recent trend claims have been made that spacetime geometry
is emerging from quantum information where entanglement is the glue. Or
that spacetime structure is encoded into patterns of entanglement. In this
talk by employing a simple toy model we would like to answer the question:
how this can happen?
It is shown that in the case of our toy model the essence of encoding is
governed by a combinatorial object, called the associahedron.
We also point out that similar combinatorial structures appear in studies
of tree level scattering amplitudes of gauge theory within a recent
incarnation of the field of S-matrix theory. These structural similarities
might be used for obtaining further insight into conceptual issues
concerning the notion of emergent space time.

Minden érdeklődőt szeretettel várunk.
