Questionable and unquestionable in the perturbation theory of non-Abelian models
Ferenc Niedermayer, Max Niedermaier, Peter Weisz
We show, by explicit computation, that bare lattice perturbation theory in the two-dimensional O(n) nonlinear models with superinstanton boundary conditions is divergent in the…
A determination of the mass gap in the O(n) sigma model
Dong-Shin Shin
We calculate the finite volume mass gap at 3-loop level in the non-linear O() -model in two dimensions in small volumes. By applying the Monte Carlo measurements of th…
Non-perturbative O(a) improvement of lattice QCD
Martin Luescher, Stefan Sint, Rainer Sommer +2
The coefficients multiplying the counterterms required for O() improvement of the action and the isovector axial current in lattice QCD are computed non-perturbatively, in the q…
New Universality Classes in One--Dimensional --Invariant Spin--Models with an --Parametric Action
Erhard Seiler, Karim Yildirim
An action with parameters, which generalizes the -model, is considered in one dimension for general . We use asymptotic expansion techniques to determine…
Exact Local Bosonic Algorithm for Dynamical Quarks
Andrea Galli, Philippe de Forcrand
We present an exact local bosonic algorithm for the simulation of dynamical fermions in lattice QCD. We show that this algorithm is a viable alternative to the Hybrid Monte Carlo a…
Some new results in O(a) improved lattice QCD
M. Lüscher, S. Sint, R. Sommer +3
It is shown how on-shell O(a) improvement can be implemented non-perturbatively in lattice QCD with Wilson quarks. Improvement conditions are obtained by requiring the PCAC relatio…
O(a) improvement of the axial current in lattice QCD to one-loop order of perturbation theory
M. Lüscher, P. Weisz
The conservation of the isovector axial current in lattice QCD with massless Wilson quarks is studied to one-loop order of perturbation theory. Following a strategy described in a…
Suppression of the negative sign problem in quantum Monte Carlo
A. Galli
We present a new Monte Carlo algorithm for simulating quantum spin systems which is able to suppress the negative sign problem. This algorithm has only a linear complexity in the l…
A new approach to significantly reduce the negative sign problem in quantum Monte Carlo
A. Galli
We present a new approach for Monte Carlo simulations of lattice quantum spin systems which is able to eliminate the negative sign problem. Its complexity is linear in the volume o…
Critical Phenomena with Linked Cluster Expansions in a Finite Volume
H. Meyer-Ortmanns, T. Reisz
Linked cluster expansions are generalized from an infinite to a finite volume. They are performed to 20th order in the expansion parameter to approach the critical region from the…
Lattice Regularization of the Chiral Schwinger Model
Christof Gattringer
We analyze the chiral Schwinger model on an infinite lattice using the continuum definition of the fermion determinant and a linear interpolation of the lattice gauge fields. For n…
Non-hermitian Exact Local Bosonic Algorithm for Dynamical Quarks
A. Borrelli, Ph. de Forcrand, A. Galli
We present an exact version of the local bosonic algorithm for the simulation of dynamical quarks in lattice QCD. This version is based on a non-hermitian polynomial approximation…
