Path integral renormalisation in loop quantum cosmology
Norbert Bodendorfer, Muxin Han, Fabian Haneder +1
A coarse graining technique akin to block spin transformations that groups together fiducial cells in a homogeneous and isotropic universe has been recently developed in the contex…

A note on coarse graining and group representations
Norbert Bodendorfer, Fabian Haneder
A coarse graining operation of spatially homogeneous quantum states based on an SU(1,1) Lie group structure has recently been proposed in [1] and used in [2] to compute an explicit…

Coarse graining as a representation change
Norbert Bodendorfer, Fabian Haneder
We discuss how SU coherent states from the discrete series allow for a natural coarse graining operation. The physical application are quantum theories based on a set of thr…
