Recent Developments in Lattice Supersymmetry
David B. Kaplan
I discuss a new approach to constructing lattices for gauge theories with extended supersymmetry. The lattice theories themselves respect certain supersymmetries, which in many cas…
A lattice theory for low energy fermions at finite chemical potential
Jiunn-Wei Chen, David B. Kaplan
We construct a lattice theory describing a system of interacting nonrelativistic spin s=1/2 fermions at nonzero chemical potential. The theory is applicable whenever the interparti…
Supersymmetry on a Euclidean Spacetime Lattice II: Theories with Eight Supercharges
Andrew G. Cohen, David B. Kaplan, Emanuel Katz +1
We formulate Euclidean spacetime lattices whose continuum limits are supersymmetric Yang-Mills theories with eight supercharges in two and three dimensions. The lattice actions are…
Supersymmetry on a Euclidean Spacetime Lattice I: A Target Theory with Four Supercharges
Andrew G. Cohen, David B. Kaplan, Emanuel Katz +1
We formulate a Euclidean spacetime lattice whose continuum limit is (2,2) supersymmetric Yang-Mills theory in two dimensions, a theory which possesses four supercharges and an anom…
