Krylov complexity in quantum field theory, and beyond [PDF]
Journal of High Energy Physics, 2022 We study Krylov complexity in various models of quantum field theory: free massive bosons and fermions on flat space and on spheres, holographic models, and lattice models with a UV-cutoff.

Fermion-bag inspired Hamiltonian lattice field theory for fermionic quantum criticality [PDF]
Physical Review D, 2019 Motivated by the fermion-bag approach, we construct a new class of Hamiltonian lattice field theories that can help us to study fermionic quantum critical points, particularly those with four-fermion interactions.

Dilaton Effective Field Theory [PDF]
Universe, 2022 We review and extend recent studies of dilaton effective field theory (dEFT) that provide a framework for the description of the Higgs boson as a composite structure.

Lattice improvement in lattice effective field theory [PDF]
The European Physical Journal A, 2018 Lattice calculations using the framework of effective field theory have been applied to a wide range few-body and many-body systems. One of the challenges of these calculations is to remove systematic errors arising from the nonzero lattice spacing. Fortunately, the lattice improvement program pioneered by Symanzik provides a formalism for doing this ...

The continuum and leading twist limits of parton distribution functions in lattice QCD
Journal of High Energy Physics, 2021 In this study, we present continuum limit results for the unpolarized parton distribution function of the nucleon computed in lattice QCD. This study is the first continuum limit using the pseudo-PDF approach with Short Distance Factorization for ...

Computers for lattice field theories [PDF]
Nuclear Physics B - Proceedings Supplements, 1994 Parallel computers dedicated to lattice field theories are reviewed with emphasis on the three recent projects, the Teraflops project in the US, the CP-PACS project in Japan and the 0.5-Teraflops project in the US. Some new commercial parallel computers are also discussed. Recent development of semiconductor technologies is briefly surveyed in relation

Relativistic N-particle energy shift in finite volume
Journal of High Energy Physics, 2021 We present a general method for deriving the energy shift of an interacting system of N spinless particles in a finite volume. To this end, we use the nonrelativistic effective field theory (NREFT), and match the pertinent low-energy constants to the ...

Soliton quantization in lattice field theories [PDF]
Communications in Mathematical Physics, 1987 Quantization of solitons in terms of Euclidean region functional integrals is developed, and Osterwalder-Schrader reconstruction is extended to theories with topological solitons. The quantization method is applied to several lattice field theories with solitons, and the particle structure in the soliton sectors of such theories is analyzed.

The flavor dependence of m ϱ /f π
Journal of High Energy Physics, 2019 We calculate the m ϱ /f π ratio in the chiral and continuum limit for SU(3) gauge theory coupled to N f = 2, 3, 4, 5, 6 fermions in the fundamental representation. Keeping all systematic effects under full control we find no statistically significant N f
