Journal of High Energy Physics, 2019 There exist two methods to study two-baryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlation function and the HAL QCD method which extracts observables from the non-local potential ...

On the three-particle analog of the Lellouch-Lüscher formula
Journal of High Energy Physics, 2021 Using non-relativistic effective field theory, we derive a three-particle analog of the Lellouch-Lüscher formula at the leading order. This formula relates the three-particle decay amplitudes in a finite volume with their infinite-volume counterparts and,

Lattice gas models derived from effective field theory
, 2004 We start from a low-energy effective field theory for interacting fermions on the lattice and expand in the hopping parameter to derive the nearest-neighbor interactions for a lattice gas model.

Lattice effective field theory for nuclei from A = 4 to A = 28 [PDF]
, 2013 We present an overview of the extension of Nuclear Lattice Effective Field Theory simulations to the regime of medium-mass nuclei. We focus on the determination of the ground-state energies of the alpha nuclei $^{16}$O, $^{20}$Ne, $^{24}$Mg and $^{28}$Si

Flow-based sampling for lattice field theories [PDF]
Proceedings of The 40th International Symposium on Lattice Field Theory — PoS(LATTICE2023)Critical slowing down and topological freezing severely hinder Monte Carlo sampling of lattice field theories as the continuum limit is approached. Recently, significant progress has been made in applying a class of generative machine learning models ...

Lattice setup for quantum field theory in AdS2 [PDF]
, 2019 Holographic Conformal Field Theories (CFTs) are usually studied in a limit where the gravity description is weakly coupled. By contrast, lattice quantum field theory can be used as a tool for doing computations in a wider class of holographic CFTs where ...

Hamiltonian Effective Field Theory Study of the N^{*}(1535) Resonance in Lattice QCD. [PDF]
Physical Review Letters, 2015 Drawing on experimental data for baryon resonances, Hamiltonian effective field theory (HEFT) is used to predict the positions of the finite-volume energy levels to be observed in lattice QCD simulations of the lowest-lying J^{P}=1/2^{-} nucleon ...

Advanced Biology, EarlyView.In vitro cancer models are advantageous for studying important processes such as tumorigenesis, cancer growth, invasion, and metastasis. The complexity and biological relevance increase depending on the model structure, organization, and composition of materials and cells.

Quark number susceptibility of high temperature and finite density QCD [PDF]
, 2007 We utilize lattice simulations of the dimensionally reduced effective field theory (EQCD) to determine the quark number susceptibility of QCD at high temperature ($T>2T_c$). We also use analytic continuation to obtain results at finite density.
