A note on the 2D NLSM free energy
Yizhuang Liu
This note contains the perturbative computation of the 2D non-linear sigma model (NLSM) energy-density in a chemical potential , at the fourth order in the coupling constant exp…
Analyticity, asymptotics and natural boundary for a one-point function of the finite-volume critical Ising chain
Yizhuang Liu
This note reports the following observation: the finite-volume expectation value of the spin operator (the one-point function) between the -even and odd ground states…
Spin-operator form factors of the critical Ising chain and their finite volume scaling limits
Yizhuang Liu
In this work, we provide a self-contained derivation of the spin-operator matrix elements in the fermionic basis, for the critical periodic Ising chain at a generic system length $…
Asymptotic Long-Distance Expansion of Euclidean Correlators in Lattice Parton Applications
Xiangdong Ji, Yizhuang Liu, Yushan Su
Bilinear Euclidean quark and gluon correlators with Wilson links have been used widely for applications of large-momentum effective field theories to computing non-perturbative col…
Asymptotics of spin-spin correlators weighted by fermion number measurements with low rapidity threshold in the 2D Ising free-fermion QFT
Yizhuang Liu
In the work, we study the averaged number of massive fermions above a low rapidity threshold , underlying the form-factor expansions of the spin-spin two-point correlators at an…
Renormalon-like factorial enhancements to power expansion/OPE in a super-renormalizable 2D quartic model
Yizhuang Liu
In this work, we investigate the effects of logarithms on the asymptotic behavior of power expansion/OPE in supper-renormalizable QFTs. We performed a careful investigation of the…
