A Gentle Introduction to Lattice Field Theory [PDF]

open access: yesEntropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

Field Theory of Quantum Antiferromagnets : From the Triangular to the Kagome Lattice [PDF]

open access: greenInternational Journal of Modern Physics B, 1996
We analyse a family of models, that interpolates between the Triangular lattice antiferromagnet (TLAF) and the Kagome lattice antiferromagnet (KLAF). We identify the field theories governing the low energy, long wavelength physics of these models. Near the TLAF the low energy field theory is a nonlinear sigma model of a SO(3) group valued field.

Quantum field theory on a growing lattice [PDF]

open access: bronzeJournal of High Energy Physics, 2004
We construct the classical and canonically quantized theories of a massless scalar field on a background lattice in which the number of points--and hence the number of modes--may grow in time. To obtain a well-defined theory certain restrictions must be imposed on the lattice.

Deligne categories in lattice models and quantum field theory, or making sense of O(N) symmetry with non-integer N [PDF]

open access: diamondJournal of High Energy Physics, 2020
When studying quantum field theories and lattice models, it is often useful to analytically continue the number of field or spin components from an integer to a real number.

Hubbard model on the honeycomb lattice: From static and dynamical mean-field theories to lattice quantum Monte Carlo simulations [PDF]

open access: greenPhysical review B, 2020
We study the one-band Hubbard model on the honeycomb lattice using a combination of quantum Monte Carlo (QMC) simulations and static as well as dynamical mean-field theory (DMFT).
