Exact Ward-Takahashi identity for the lattice N=1 Wess-Zumino model
A. Feo
The lattice Wess-Zumino model written in terms of the Ginsparg-Wilson relation is invariant under a generalized supersymmetry transformation which is determined by an iterative pro…
Density Matrix Renormalization Group Study of the Disorder Line in the Quantum ANNNI Model
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We apply Density Matrix Renormalization Group methods to study the phase diagram of the quantum ANNNI model in the region of low frustration where the ferromagnetic coupling is lar…
Critical behavior in a non-local interface model
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
The Raise and Peel model is a recently proposed one-dimensional statistical model describing a fluctuating interface. The evolution of the model follows from the competition betwee…
The high density region of QCD in a large mass and chemical potential model
Roberto De Pietri, Alessandra Feo, Erhard Seiler +1
We study the high density region of QCD within an effective model obtained in the frame of the hopping parameter expansion. The model still acknowledges the sign problem peculiar t…
Dynamical supersymmetry breaking and phase diagram of the lattice Wess-Zumino model
Matteo Beccaria, Gian Fabrizio De Angelis, Massimo Campostrini +1
We study dynamical supersymmetry breaking and the transition point by non-perturbative lattice techniques in a class of two-dimensional N=1 Wess-Zumino model. The method is based o…
Exact lattice Ward-Takahashi identity for the N=1 Wess-Zumino model
Marisa Bonini, Alessandra Feo
We consider a lattice formulation of the four dimensional N=1 Wess-Zumino model that uses the Ginsparg-Wilson relation. This formulation has an exact supersymmetry on the lattice.…
