Title: Adventures in Holographic Dimer Models

Abstract

We abstract the essential features of holographic dimer models, and develop several new applications of these models. Firstly, semi-holographically coupling free band fermions to holographic dimers, we uncover novel phase transitions between conventional Fermi liquids and non-Fermi liquids, accompanied by a change in the structure of the Fermi surface. Secondly, we make dimer vibrations propagate through the whole crystal by way of double trace deformations, obtaining nontrivial band structure. In a simple toy model, the topology of the band structure experiences an interesting reorganization as we vary the strength of the double trace deformations. Finally, we develop tools that would allow one to build, in a bottom-up fashion, a holographic avatar of the Hubbard model.

  • A series of highly enantioselective transformations, such as the Sharpless asymmetric epoxidation and Jacobsen hydrolytic kinetic resolution, were utilized to achieve the complete stereoselective synthesis of β-O-4 lignin dimer models containing the S, G, and H subunits with excellent ee (>99%) and moderate to high yields. This unprecedented synthetic method can be exploited for enzymatic, microbial, and chemical investigations into lignin’s degradation and depolymerization as related to its stereochemical constitution. Preliminary degradation studies using enantiopure Co(salen) catalysts are also reported.
  • Irreversible adsorption of diatomics on crystalline surfaces is sometimes modeled as random dimer filling of adjacent pairs of sites on a lattice. We note that this process can be implemented in two distinct ways: (i) randomly pick adjacent pairs of sites, {ital jj}{prime}, and fill {ital jj}{prime} only if both are empty (horizontal transition state); or (ii) randomly pick a single site, {ital j}, and if {ital j} and at least one neighbor are empty, then fill {ital j} and a randomly chosen empty neighbor (vertical transition state). Here it is instructive to consider processes which also include competitive randommore » monomer filling of single sites. We find that although saturation (partial) coverages differ little between the models for pure dimer filling, there is a significant difference for comparable monomer and dimer filling rates. We present exact results for saturation coverage behavior for a linear lattice, and estimates for a square lattice. Ramifications for simple models of CO oxidation on surfaces are indicated.« less
  • We present numerical results for the magnetic susceptibility of a Heisenberg antiferromagnetic spin ladder as a function of temperature and the spin-spin interaction strengths [ital J][sub [perpendicular]] and [ital J][sub [parallel]]. These are contrasted with bulk-limit results for the dimer chain. A fit to the experimental susceptibility of the candidate spin-ladder compound vanadyl pyrophosphate, (VO)[sub 2]P[sub 2]O[sub 7], gives the parameters [ital J][sub [perpendicular]]=7.82 meV and [ital J][sub [parallel]]=7.76 meV. With these values we predict a singlet-triplet energy gap of [ital E][sub gap]=3.9 meV, and give a numerical estimate of the ladder triplet dispersion relation [omega]([ital k]). In contrast, amore » fit to the dimer-chain model leads to [ital J][sub 1]=11.11 meV and [ital J][sub 2]=8.02 meV, which predicts a gap of [ital E][sub gap]=4.9 meV.« less
  • Behavior of doped fermions in Z{sub 2} gauge theories for the quantum dimer and eight-vertex models is studied. Fermions carry charge and spin degrees of freedom. In the confinement phase of the Z{sub 2} gauge theories, these internal symmetries are spontaneously broken and a superconducting or Neel state appears. On the other hand in the deconfinement-topologically ordered state, all symmetries are respected. From the view point of the quantum dimer and eight-vertex models, this result indicates interplay of the phase structure of the doped fermions and background configuration of the dimer or the eight-vertex groundstate. At the quantum phase transitionsmore » in these systems, structure of the doped fermions groundstate and also that of the background dimer or eight-vertex groundstate both change. Translational symmetry breaking induces a superconducting or antiferromagnetic state of the doped fermions.« less
