    "abstract": "The high-$T_c$ cuprates are possible candidates for d-wave superconductivity,\nwith the Cooper pair wave function belonging to a non-trivial irreducible\nrepresentation of the lattice point group. We argue that this d-wave symmetry\nis related to a special form of the fermionic kinetic energy and does not\nrequire any novel pairing mechanism. In this context, we present a detailed\nstudy of the bound states and resonances formed by two lattice fermions\ninteracting via a non-retarded potential that is attractive for nearest\nneighbors but repulsive for other relative positions. In the case of strong\nbinding, a pair formed by fermions on adjacent lattice sites can have a small\neffective mass, thereby implying a high condensation temperature. For a weakly\nbound state, a pair with non-trivial symmetry tends to be smaller in size than\nan s-wave pair. These and other findings are discussed in connection with the\nproperties of high-$T_c$ cuprate superconductors.",
