Tackling the Sign Problem
T D Kieu, C J Griffin
To tackle the sign problem in the simulations of systems having indefinite or complex-valued measures, we propose a new approach which yields statistical errors smaller than the cr…
Monte Carlo Simulations with Indefinite and Complex-Valued Measures
T D Kieu, C J Griffin
A method is presented to tackle the sign problem in the simulations of systems having indefinite or complex-valued measures. In general, this new approach is shown to yield statist…
Simulations with Complex Measures
T D Kieu, C J Griffin
Towards a solution to the sign problem in the simulations of systems having indefinite or complex-valued measures, we propose a new approach which yields statistical errors smaller…
Fermionic Field Theory and Gauge Interactions on Random Lattices
C. J. Griffin, T. D. Kieu
Random-lattice fermions have been shown to be free of the doubling problem if there are no interactions or interactions of a non-gauge nature. However, gauge interactions impose st…
How Do Fermions Behave on a Random Lattice?
C J Griffin, T D Kieu
Comparing random lattice, naive and Wilson fermions in two dimensional abelian background gauge field, we show that the doublers suppressed in the free field case are revived for r…
Fermion Doubling and Gauge Invariance on Random Lattices
C J Griffin, T D Kieu
Random-lattice fermions have been shown to be free of the doubling problem if there are no interactions or interactions of a non-gauge nature. On the other hand, gauge interactions…
