Supersymmetric Model of Spin-1/2 Fermions on a Chain
In recent work,N = 2 supersymmetry has been proposed as a tool for the analysis of itinerant, correlated fermions on a lattice. In this paper we extend these considerations to the case of lattice fermions with spin 1/2 . We introduce a model for correlated spin-1/2 fermions with a manifest N = 4 supersymmetry, and analyze its properties. The supersymmetric ground states that we find represent h...
متن کاملA solvable model of a random spin-12 XY chain
The paper presents exact calculations of thermodynamic quantities for the spin2 isotropic XY chain with random lorentzian intersite interaction and transverse field that depends linearly on the surrounding intersite interactions. PACS codes: 75.10.-b
متن کاملSpin chain sigma models with fermions
The complete one-loop planar dilatation operator of N = 4 supersymmetric Yang-Mills is isomorphic to the hamiltonian of an integrable PSU(2, 2|4) quantum spin chain. We construct the non-linear sigma models describing the continuum limit of the SU(1|3) and SU(2|3) sectors of the complete N = 4 chain. We explicitely identify the spin chain sigma model with the one for a superstring moving in AdS...
متن کاملSupersymmetric Models for Fermions on a Lattice
We investigate the large-N behaviour of simple examples of supersymmetric interactions for fermions on a lattice. Witten’s supersymmetric quantum mechanics and the BCS model appear just as two different aspects of one and the same model. For the BCS model, supersymmetry is only respected in a coherent superposition of Bogoliubov states. In this coherent superposition mesoscopic observables show...
