Efficient Cluster Algorithm for CP(N-1) Models
B. B Beard, M. Pepe, S. Riederer +1
Despite several attempts, no efficient cluster algorithm has been constructed for CP(N-1) models in the standard Wilson formulation of lattice field theory. In fact, there is a no-…
Study of the 2-d CP(N-1) models at θ=0 and π
B. B. Beard, M. Pepe, S. Riederer +1
We present numerical results for 2-d CP(N-1) models at θ=0 and πobtained in the D-theory formulation. In this formulation we construct an efficient cluster algorithm and we show nu…
Study of CP(N-1) θ-Vacua by Cluster-Simulation of SU(N) Quantum Spin Ladders
B. B. Beard, M. Pepe, S. Riederer +1
D-theory provides an alternative lattice regularization of the (1+1)-d CP(N-1) quantum field theory. In this formulation the continuous classical CP(N-1) fields emerge from the dim…
D-Theory: Field Quantization by Dimensional Reduction of Discrete Variables
R. Brower, S. Chandrasekharan, S. Riederer +1
D-theory is an alternative non-perturbative approach to quantum field theory formulated in terms of discrete quantized variables instead of classical fields. Classical scalar field…
Zero modes of six-dimensional Abelian vortices
Massimo Giovannini, Jean-Vincent Le Be, Stephane Riederer
We analyze the fluctuations of Nielsen-Olesen vortices arising in the six-dimensional Abelian-Higgs model. The regular geometry generated by the defect breaks spontaneously six-dim…
