Diffeomorphism-invariant Approach to Asymptotically Safe Quantum Gravity
Friederike Ihssen, Benjamin Knorr, Silas Mezger +2
We provide a novel diffeomorphism-invariant approach to asymptotically safe metric quantum gravity. It is based on physics-informed renormalisation group flows with a renormalisati…
Quantum critical fan and emergent relativistic symmetry of two-dimensional Dirac semimetals
Friederike Ihssen, Bilal Hawashin, Mireia Tolosa-Simeón +1
Two-dimensional Dirac semimetals near a quantum critical point can be described by Gross--Neveu--Yukawa models. In view of recent experimental advances exhibiting a transition from…
Solving sign problems with physics-informed kernels
Friederike Ihssen, Renzo Kapust, Jan M. Pawlowski
In the present work we construct a novel generative architecture for systems with complex probability distributions. In general, these sampling tasks come with two challenges: reso…
Critical aging and relaxation dynamics in long-range systems
Valerio Pagni, Friederike Ihssen, Nicolò Defenu
We study the dynamical scaling of long-range models after a sudden quench to the critical temperature, using the functional renormalization group approach. We chara…
