متن کاملPairing in two-dimensional boson-fermion mixtures
The possibilities of pairing in two-dimensional boson-fermion mixtures are carefully analyzed. It is shown that the boson-induced attraction between two identical fermions dominates the pwave pairing at low density. For a given fermion density, the pairing gap becomes maximal at a certain optimal boson concentration. The conditions for observing pairing in current experiments are discussed. PAC...
متن کاملTandem pairing in heavy-fermion superconductors.
We consider the internal structure of a d-wave heavy-fermion superconducting condensate, showing that it necessarily contains two components condensed in tandem: pairs of quasiparticles on neighboring sites and composite pairs consisting of two electrons bound to a single local moment. These two components draw upon the antiferromagnetic and Kondo interactions to cooperatively enhance the super...
متن کاملSpinning Flavour Branes and Fermion Pairing Instabilities
We consider probe Dp-branes, p = 3, 5, 7, in global AdS5 × S, rotating along an internal direction in the S. These are dual to strongly interacting N = 4 SYM on S with massless fundamental flavours, in the presence of an R-symmetry chemical potential for flavour fermions. For massless, “AdS-filling” Dp-brane embeddings at zero temperature, we find an infinite set of threshold values of the chem...
متن کاملComposite Fermion Pairing in Bilayer Quantum Hall Systems
We derive the effective Hamiltonian for the composite fermion in double-layer quantum Hall systems with inter-layer tunneling at total Landau-level filling factor ν = 1/m, where m is an integer. We find that the ground state is the triplet p-wave BCS pairing state of the composite fermions. At ν = 1/2, the ground state of the system evolves from the Halperin (3, 3, 1)-state toward the Pfaffian-...
