Query: Non-Fermi-liquid at (2+1)d ferromagnetic quantum critical point   We construct a two-dimensional lattice model of fermions coupled to Ising
ferromagnetic critical fluctuations. Using extensive sign-problem-free quantum
Monte Carlo simulations, we show that the model realizes a continuous itinerant
quantum phase transition. In comparison with other similar itinerant quantum
critical points (QCPs), our QCP shows much weaker superconductivity tendency
with no superconducting state down to the lowest temperature investigated,
hence making the system a good platform for the exploration of quantum critical
fluctuations. Remarkably, clear signatures of non-Fermi-liquid behavior in the
fermion propagators are observed at the QCP. The critical fluctuations at the
QCP partially resemble Hertz-Millis-Moriya behavior. However, careful scaling
analysis reveals that the QCP belongs to a different universality class,
deviating from both (2+1)d Ising and Hertz-Millis-Moriya predictions.
