Machine Learning and Variational Algorithms for Lattice Field Theory
Discretizing fields on a spacetime lattice is the only known general and non-perturbative regulator for quantum field theory. The lattice formulation has, for example, played an important role in predicting properties of QCD in the strongly coupled regime, where perturbative methods break down. To …

Eliminating critical slowing down in Monte Carlo calculations
… to improve the major numerical difficulties in lattice field theory. Traditional Metropolis and heat bath Monte Carlo methods in lattice calculations break down whenever one tries to calculate thermodynamic quantities near critical points; this phenomenon is called Critical Slowing Down, (CSD). …

Strongly coupled fermions on the lattice
… with the pioneering work of Ken Wilson, lattice field theory has come a long way. Lattice formulations have enabled us to probe the non-perturbative structure of theories such as QCD and have also helped in exploring the phase structure and classification of phase transitions in a variety …

EXPANSION AFTER INFLATION AND REHEATING WITH A CHARGED INFLATON
… mechanism for the generation of cosmic magnetic fields. The transition from an inflationary to a radiation-dominated, thermal phase (reheating) is likely to be phenomenologically rich. Reheating could include explosive particle production and various other non-perturbative, non-linear and …

Weak decays of beautiful pseudoscalar mesons with Lattice Quantum Chromodynamics
… study a selection of decays of $B$ mesons with Lattice Quantum Chromodynamics. After introducing these modern methods, I report on my progress on calculating the vector current form factors for $B_c \to D_s$. This decay is allowed at the one-loop level and so my vector current form factors will …
