Tensor renormalization group study of two-dimensional U(1) lattice gauge theory with a θ term
Journal of High Energy Physics, 2020 We make an analysis of the two-dimensional U(1) lattice gauge theory with a θ term by using the tensor renormalization group. Our numerical result for the free energy shows good consistency with the exact one at finite coupling constant.

RG-inspired machine learning for lattice field theory
EPJ Web of Conferences, 2018 Machine learning has been a fast growing field of research in several areas dealing with large datasets. We report recent attempts to use renormalization group (RG) ideas in the context of machine learning.

Lattice field theory simulations of Dirac semimetals [PDF]
, 2017 In this paper the observed Dirac semimetals Na$_3$Bi and Cd$_3$As$_2$ are studied within lattice simulation. We formulate lattice field theory with rooted staggered fermions on anisotropic lattice.

Lattice Field Theory Methods in Modern Biophysics [PDF]
, 2006 An effective field theory exists describing a very large class of biophysically interesting Coulomb gas systems: the lowest order (mean-field) version of this theory takes the form of a generalized Poisson-Boltzmann theory.
