Phase boundary and finite temperature crossovers of the quantum Ising model in two dimensions
P. Strack, P. Jakubczyk
We revisit the two-dimensional quantum Ising model by computing renormalization group flows close to its quantum critical point. The low but finite temperature regime in the vicini…

Anomalous scaling of fermions and order parameter fluctuations at quantum criticality
P. Strack, S. Takei, W. Metzner
We analyze the quantum phase transition between a semimetal and a superfluid in a model of attractively interacting fermions with a linear dispersion. The quantum critical properti…
