Title: Pairing from strong repulsion in triangular lattice Hubbard model

Abstract

Here, we propose a pairing mechanism between holes in the dilute limit of doped frustrated Mott insulators. Hole pairing arises from a hole-hole-magnon three-body bound state. This pairing mechanism has its roots on single-hole kinetic energy frustration, which favors antiferromagnetic (AFM) correlations around the hole. We demonstrate that the AFM polaron (hole-magnon bound state) produced by a single hole propagating on a field-induced polarized background is strong enough to bind a second hole. The effective interaction between these three-body bound states is repulsive, implying that this pairing mechanism is relevant for superconductivity.

Heavy quasiparticles and Cooper-pair interaction in the Hubbard model

Journal Article Ohkawa, F J - Physical Review, B: Condensed Matter

The Hubbard model is studied in the vicinity of the Mott transition. Local and quantal spin fluctuations are completely included through the mapping to the Anderson model; a local Kondo temperature {ital T}{sub {ital K}} is defined as their characteristic temperature or energy scale. Antiferromagnetic spin fluctuations are included perturbatively in terms of 1/{ital d} and to leading order in {ital k}{sub {ital B}}T{sub {ital K}}/{ital U} with {ital d} being the spatial dimensionality, {ital k}{sub {ital B}} the Boltzmann constant, and {ital U} the intrasite repulsion. The two different kinds of spin fluctuations are responsible for the formation ofmore »« less

Nonperturbative results for attractive Hubbard pairings in triangular lattices

Journal Article Perez, L A ; Navarro, O ; Wang, C - Physical Review, B: Condensed Matter

The electron pairing problem is studied by means of the extended Hubbard Hamiltonian. The original many-body problem is mapped onto a tight-binding one in a higher dimensional space, where the problem can be solved in an exact way. In a triangular lattice, the effects of the frustration of antibonding states on the electronic correlation are analyzed in detail. It is found that the hole pairing is always stronger than the electron case, in contrast with the bipartite lattices, where there is a complete symmetry between electron and hole pairings. The ground state of two holes, when the attractive nearest-neighbor interactionmore »« less

Pairing in the two-dimensional Hubbard model from weak to strong coupling

Journal Article Rømer, Astrid T. ; Maier, Thomas A. ; Kreisel, Andreas ; ... - Physical Review Research

The Hubbard model is the simplest model that is believed to exhibit superconductivity arising from purely repulsive interactions, and has been extensively applied to explore a variety of unconventional superconducting systems. Here we study the evolution of the leading superconducting instabilities of the single-orbital Hubbard model on a two-dimensional square lattice as a function of onsite Coulomb repulsion U and band filling by calculating the irreducible particle-particle scattering vertex obtained from dynamical cluster approximation (DCA) calculations, and compare the results to both perturbative Kohn-Luttinger (KL) theory as well as the widely used random phase approximation (RPA) spin-fluctuation pairing scheme.

Low-density repulsive Fermi gas in two dimensions: Bound-pair excitations and Fermi-liquid behavior

Journal Article Engelbrecht, J R ; Randeria, M - Physical Review, B: Condensed Matter; (United States)

We study the dilute-gas expansion for a two-dimensional Fermi system with arbitrary short-range repulsive interactions. In contrast with the three-dimensional case, we find an unusual pole in the vertex part in the particle-particle channel, for all center-of-mass momenta {ital q}{lt}2{ital k}{sub {ital F}}. We show that this represents an excitation consisting of bound hole pairs, which disperses down to zero energy at {ital q}=2{ital k}{sub {ital F}}. We study the effect of these bound states on the single-particle self-energy and find that the quasiparticles are well defined. Thus in the low-density regime, there is no breakdown of Fermi-liquid theory. Inmore »« less

Spin liquid state in the disordered triangular lattice Sc₂Ga₂CuO₇ revealed by NMR

Journal Article Khuntia, P. ; Kumar, R. ; Mahajan, A. V. ; ... - Physical Review B

We present microscopic magnetic properties of a two-dimensional triangular lattice Sc₂Ga₂CuO₇, consisting of single and double triangular Cu planes. An antiferromagnetic (AFM) exchange interaction J/k_B ≈ 35 K between Cu²⁺ (S = 1/2) spins in the triangular biplane is obtained from the analysis of intrinsic magnetic susceptibility data. The intrinsic magnetic susceptibility, extracted from ⁷¹Ga NMR shift data, displays the presence of AFM short range spin correlations and remains finite down to 50 mK, suggesting a nonsinglet ground state. The nuclear spin-lattice relaxation rate (1/T₁) reveals a slowing down of Cu²⁺ spin fluctuations with decreasing T down to 100 mK.more »« less
