Exactly solvable model of Fermi arcs and pseudogap
نویسندگان
چکیده
We introduce a very simple and exactly solvable model that supports Fermi arcs in its ground state excitation spectrum. These come pairs, merge into what we call pseudo surface along which fermions are gapped; this fermion gap is naturally identified as pseudogap. Comparison will be made with phenomenology of high temperature cuprate superconductors.

Fermi-transitions in an exactly solvable model
An exactly solvable model suitable for the description of single and double-beta decay processes of the Fermi-type is introduced. The model is equivalent to the exact shell-model treatment of protons and neutrons in a single j-shell. Exact eigenvalues and eigenvectors are compared to those corresponding to the hamiltonian in the quasiparticle basis (qp) and with the results of both the standard...
متن کاملExactly solvable toy model for the pseudogap state
We present an exactly solvable toy model which describes the emergence of a pseudogap in an electronic system due to a fluctuating off-diagonal order parameter. In one dimension our model reduces to the fluctuating gap model (FGM) with a gap ∆(x) that is constrained to be of the form ∆(x) = Ae, where A andQ are random variables. The FGM was introduced by Lee, Rice and Anderson [Phys. Rev. Lett....
متن کاملAn Exactly Solvable Model for the Fermi Contact Interaction
A model for the Fermi contact interaction is proposed in which the nuclear moment is represented as a magnetized spherical shell of radius ro. For a hydrogen-like system thus perturbed, the Schr6dinger equation is solvable without perturbation theory by use of the Coulomb Green's function. Approximation formulas are derived in terms of a quantum defect in the Coulombic energy formula. It is sho...
متن کاملPseudogap Fermi-Bose Kondo model.
We consider a magnetic impurity coupled to both fermionic quasiparticles with a pseudogap density of states and bosonic spin fluctuations. Using renormalization group and large-N calculations we investigate the phase diagram of the resulting Fermi-Bose Kondo model. We show that the Kondo temperature is strongly reduced by low-energy spin fluctuations, and make connections to experiments in cupr...
متن کاملSimple Exactly Solvable Models of non-Fermi Liquids
We generalize the model of Hatsugai and Kohmoto [J. Phys. Soc. Jpn, 61, 2056 (1992)] and find ground states which do not show the properties of Fermi liquids. We work in two space dimensions, but it is straightforward to generalize to higher dimensions. The ground state is highly degenerate and there is no discontinuity in the momentum distribution; i.e., there is no Fermi surface. The Green’s ...
