Exotic $U(1)$ symmetries, duality, and fractons in 3+1-dimensional quantum field theory [PDF]
, 2020 We extend our exploration of nonstandard continuum quantum field theories in 2+1 dimensions to 3+1 dimensions. These theories exhibit exotic global symmetries, a peculiar spectrum of charged states, unusual gauge symmetries, and surprising dualities ...

Real-time spin systems from lattice field theory
Journal of High Energy Physics, 2023 We construct a lattice field theory method for computing the real-time dynamics of spin systems in a thermal bath. This is done by building on previous work of Takano with Schwinger-Keldysh and functional differentiation techniques. We derive a Schwinger-

Relativistic-invariant formulation of the NREFT three-particle quantization condition
Journal of High Energy Physics, 2022 A three-particle quantization condition on the lattice is written down in a manifestly relativistic-invariant form by using a generalization of the non-relativistic effective field theory (NREFT) approach.

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.

Towards Novel Insights in Lattice Field Theory with Explainable Machine Learning [PDF]
Physical Review D, 2020 Machine learning has the potential to aid our understanding of phase structures in lattice quantum field theories through the statistical analysis of Monte Carlo samples. Available algorithms, in particular those based on deep learning, often demonstrate

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,

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 ...

Thermal QCD in a non-uniform magnetic background
Journal of High Energy Physics, 2023 Off-central heavy-ion collisions are known to feature magnetic fields with magnitudes and characteristic gradients corresponding to the scale of the strong interactions.

Parton distribution functions from Ioffe time pseudo-distributions
Journal of High Energy Physics, 2019 In this paper, we present a detailed study of the unpolarized nucleon parton distribution function (PDF) employing the approach of parton pseudo-distribution func- tions. We perform a systematic analysis using three lattice ensembles at two volumes, with

Radial lattice quantization of 3D ϕ4 field theory [PDF]
Physical Review D, 2020 The quantum extension of classical finite elements, referred to as quantum finite elements ({\bf QFE})~\cite{Brower:2018szu,Brower:2016vsl}, is applied to the radial quantization of 3d $\phi^4$ theory on a simplicial lattice for the $\mathbb R \times ...
