Supersymmetric quantum mechanics on the lattice: III. Simulations and algorithms
David Baumgartner, Urs Wenger
In the fermion loop formulation the contributions to the partition function naturally separate into topological equivalence classes with a definite sign. This separation forms the…
Supersymmetric quantum mechanics on the lattice: II. Exact results
David Baumgartner, Urs Wenger
Simulations of supersymmetric field theories with spontaneously broken supersymmetry require in addition to the ultraviolet regularisation also an infrared one, due to the emergenc…
Supersymmetric quantum mechanics on the lattice: I. Loop formulation
David Baumgartner, Urs Wenger
Simulations of supersymmetric field theories on the lattice with (spontaneously) broken supersymmetry suffer from a fermion sign problem related to the vanishing of the Witten inde…
Spontaneous supersymmetry breaking in the two-dimensional N=1 Wess-Zumino model
Kyle Steinhauer, Urs Wenger
We study the phase diagram of the two-dimensional N=1 Wess-Zumino model on the lattice using Wilson fermions and the fermion loop formulation. We give a complete nonperturbative de…
Spontaneous supersymmetry breaking in the 2d N=1 Wess-Zumino model
David Baumgartner, Kyle Steinhauer, Urs Wenger
We study the phase diagram of the two-dimensional N=1 Wess-Zumino model using Wilson fermions and the fermion loop formulation. We give a complete non-perturbative determination of…
Exact results for supersymmetric quantum mechanics on the lattice
David Baumgartner, Urs Wenger
We discuss N=2 supersymmetric quantum mechanics on the lattice using the fermion loop formulation. In this approach the system naturally decomposes into a bosonic and fermionic sec…
Supersymmetry breaking on the lattice: the N=1 Wess-Zumino model
David Baumgartner, Kyle Steinhauer, Urs Wenger
We discuss spontaneous supersymmetry breaking in the N=1 Wess-Zumino model in two dimensions on the lattice using Wilson fermions and the fermion loop formulation. In that formulat…
Simulation of supersymmetric models on the lattice without a sign problem
David Baumgartner, Urs Wenger
Simulations of supersymmetric models on the lattice with (spontaneously) broken supersymmetry suffer from a fermion sign problem related to the vanishing of the Witten index. We pr…
