Critical scaling for spectral functions
Konrad Kockler, Jan M. Pawlowski, Jonas Wessely
We study real-time scalar -theory in 2+1 dimensions near criticality. Specifically, we compute the single-particle spectral function and that of the -channel four-point fun…
Juggling with Tensor Bases in Functional Approaches
Jens Braun, Andreas Geißel, Jan M. Pawlowski +2
Systematic expansion schemes in functional approaches require the inclusion of higher order vertices. These vertices are expanded in independent tensor bases with a rapidly increas…
Physics-informed renormalisation group flows
Friederike Ihssen, Jan M. Pawlowski
The physics of strongly correlated systems offers some of the most intriguing physics challenges such as competing orders or the emergence of dynamical composite degrees of freedom…
