    Notes:
    [Auszug] The character of the ground state of an antiferromagnetic insulator is fundamentally altered following addition of even a small amount of charge. The added charge is concentrated into domain walls across which a π phase shift in the spin correlations of the host material is induced. In two ...

    Abstract We consider the standard Hubbard model in the U=∞ limit. We show that, for any finite lattice with all positive hopping matrix elements, t i,j 〉0, the ground state energy of the system containing two particles in excess of half filling plus the energy of the system at half filling is never lower than twice the energy of the system with a single extra particle. Similar results are obtained for ‘holes’ when the lattice is bipartite. As a byproduct, we obtain a simple alternative proof of Tasaki's generalization of the Nagaoka theorem for non-bipartite lattices (but without the uniqueness clause).

    Notes:
    Abstract We study a class of two-dimensional spin-1/2 Heisenberg antiferromagnets, introduced by Klein [1], in which the nearest-neighbor term is supplemented by next-nearest-neighbor pair and four-body interactions, producing additional frustration. For certain lattices, including e.g. the hexagonal lattice, we prove that any finite subset which admits a dimer covering has a ground state space spanned by valence bond states, each of which consists only of nearest-neighbor (dimer) singlet pairs. We also establish linear independence of these valence bond states. The possible relevance to resonating-valence-bond theories of high-temperature superconductors is briefly discussed. In particular, our results apply both to regular subsets of the lattice and to subsets with static holes.

    Notes:
    Abstract The Fermi liquid theory of the normal state and the BCS-Eliashberg theory of the superconducting state were designed for good metals not for doped antiferromagnetic insulators, such as the high temperature superconductors. Consequently, it is necessary to understand the electronic structure of the doped insulator and to develop a new mechanism and many-body theory of superconductivity for these materials. It will be argued that, since the motion of a single hole in an antiferromagnet is frustrated, the driving force for the physics of a finite concentration of doped holes is the need to reduce their zero-point kinetic energy. This proceeds in three steps that are reflected in a sequence of crossovers and phase transitions. First of all, the system forms a charge-inhomogeneous state – an electronic liquid crystal phase, involving an array of metallic stripes, which lowers the kinetic energy along a stripe. In the direction perpendicular to the stripes, the kinetic energy is lowered by pair hopping, which proceeds in two steps. Local pair hopping induces spin pairing and then, at a lower temperature, pair hopping from stripe to stripe produces superconducting phase coherence. Some of the experimental support for the various aspects of this model will be described.

    Notes:
    Abstract A phenomenological approach is applied to explore signatures of disordered charge stripes and antiphase spin domains in single-particle properties of the high-temperature superconductors. Stripe phases are shown to explain many experimentally observed unusual features measured in angle-resolved photoemission and optical spectroscopy. It is argued that disordered and fluctuating stripe phases are a common feature of high-temperature superconductors, supported by the additional evidence from neutron scattering and NMR.
