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…
Fisher zeros and RG flows for with flavors
Zechariah Gelzer, Yuzhi Liu, Yannick Meurice +1
We calculate the Fisher zeros for gauge theory with different flavors of staggered fermions for various values of the fermion mass. We discuss the finite-size scaling…
Heavy-meson semileptonic decays for the Standard Model and beyond
Yuzhi Liu, Ran Zhou, Jon A. Bailey +25
We calculate the form factors for the semileptonic decays and with lattice QCD. We work at several lattice spacings and a range of light quark mass…
Comparing Tensor Renormalization Group and Monte Carlo calculations for spin and gauge models
Yannick Meurice, Alan Denbleyker, Yuzhi Liu +5
We show that the Tensor Renormalization Group (TRG) method can be applied to O(N) spin models, principal chiral models and pure gauge theories (Z2, U(1) and SU(2)) on (hyper) cubic…
Controlling sign problems in spin models using tensor renormalization
Alan Denbleyker, Yuzhi Liu, Y. Meurice +5
We consider the sign problem for classical spin models at complex on lattices. We show that the tensor renormalization group method allows reliable calculat…
Tensor renormalization group study of classical XY model on the square lattice
J. F. Yu, Z. Y. Xie, Y. Meurice +6
Using the tensor renormalization group method based on the higher-order singular value decom- position, we have studied the thermodynamic properties of the continuous XY model on t…
