Finite size scaling of conformal theories in the presence of a near-marginal operator
Anqi Cheng, Anna Hasenfratz, Yuzhi Liu +2
The slowly evolving gauge coupling of gauge-fermion systems near the conformal window makes numerical investigations of these models challenging. We consider finite size scaling an…
Improved Lattice Renormalization Group Techniques
Gregory Petropoulos, Anqi Cheng, Anna Hasenfratz +1
We compute the bare step-scaling function for SU(3) lattice gauge theory with massless fundamental fermions, using the non-perturbative Wilson-flow-optimized Monte…
Determining the mass anomalous dimension through the eigenmodes of Dirac operator
Anqi Cheng, Anna Hasenfratz, Gregory Petropoulos +1
We define a scale-dependent effective mass anomalous dimension from the scaling of the mode number of the massless Dirac operator, which connects the perturbative of an asymp…
Finite size scaling and the effect of the gauge coupling in 12 flavor systems
Anna Hasenfratz, Anqi Cheng, Gregory Petropoulos +1
Finite size scaling is a powerful tool to study the critical properties of systems governed by one relevant operator, assuming all irrelevant operators have scaling dimensions much…
Reaching the chiral limit in many flavor systems
Anna Hasenfratz, Anqi Cheng, Gregory Petropoulos +1
We present a brief overview of our recent lattice studies of SU(3) gauge theory with N_f = 8 and 12 fundamental fermions, including some new and yet-unpublished results. To explore…
Scale-dependent mass anomalous dimension from Dirac eigenmodes
Anqi Cheng, Anna Hasenfratz, Gregory Petropoulos +1
We investigate the eigenmodes of the massless Dirac operator to extract the scale-dependent fermion mass anomalous dimension gamma_m(mu). By combining simulations on multiple latti…
