Quantum Field Theory (QFT) on the Lattice
2016In 1964, Gell-Mann [1] and Zweig [2] proposed that hadrons, the particles which experience strong interactions, are made of quarks. Quarks are confined within hadrons and never seen in isolation. Electron-nucleon scattering experiments at large momentum transfer could be explained by assuming the nucleon is made of almost-free point-like constituents ...

Quantum Field Theories on the Lattice : Concepts behind their Numerical Simulations
AIP Conference Proceedings, 2011We review the basic ideas behind numerical simulations of quantum field theory, which lead to non‐perturbative results in particle physics. We first sketch the functional integral formulation of quantum mechanics, its transition to Euclidean time and the link to statistical mechanics.

MCMC and Quantum Field Theories on a Lattice
2020We can consider relativistic quantum field theory as the quantum mechanics of fields defined on a spacetime. A field has infinite number of degrees of freedom since it can take a value at every point in spacetime.

The ground state phase diagram of the quantum spin-1/2 Heisenberg antiferromagnet in the presence of nearest-neighbor (J(1)) and next-nearest-neighbor (J(2)) interactions (J(1)-J(2) model) on a stacked square lattice, where we introduce an interlayer coupling through nearest-neighbor bonds of strength J(), is studied within the framework of the ...

Quantum Field Theories on Lattice: (i) QCD Topology, and (ii) Non-perturbative Gauge-Fixing
Few-Body Systems, 2018After a brief introduction to some of the salient features, I present recent results of our group at SINP on two long-standing problems: (i) chiral and topological properties of lattice QCD with Wilson fermions, and (ii) non-perturbative gauge-fixing to address chiral gauge theories on lattice.

The chiral order in the spin 1/2 X X Z antiferromagnet H = J ∑(σ i x σ j x +σ i y σ j y +Δσ i z σ j z ) and especially in the X Y antiferromagnet on a two-dimensional triangular lattice is studied using the super-effective-field theory. In the X Y model the size dependence of the critical temperatures indicates the existence of the long-range chiral ...
