Stochastic Dynamics on Integrable Lattice Models
… some new results related to the six-vertex and dimer model. One theme is the construction and analysis of Markov processes which are naturally associated to these lattice models. Certain integrability properties of the six-vertex and dimer model, often related to the Yang–Baxter equation, allow …

Optical properties of size selected nanocrystallites in porous silicon
… theoretical photoluminescence predictions of the dimer model. There is a dramatic enhancement in the fluorescence efficiency for sizes below a critical size of 1.4 nm, the size for which the radiative states become stable against tunneling and thermal activation. The fluorescence exhibits a large …

Planar Orbital Method for Surface Electronic Structures
… Si(001) 2 x 1 surface with symmetric and buckled dimers, As/Si(001) 2 x 1 and Sb/Si(001) 2 x 1 surfaces with symmetric dimers, and the hydrogen-passivated Si(001) 2 x 1 surface, as well as the reflectance-difference spectra of Si(001) 2 x 1 and 2 x 2 surfaces. The calculating work function of …

Random geometry in two and three dimensions
… geometry is the interplay between discrete models and continuum ones that appear in scaling limits. Surprising structure and symmetry often arises in these scaling limits, leading to an interplay between combinatorics, probability, complex analysis, and geometry. The dimer model is one of …

Functional and mechanistic studies of human mitochondrial carriers
… This was the only extant evidence in favour of a dimer model. Two-reactant initial-velocity experiments were performed with the human ADP/ATP, oxoglutarate, dicarboxylate, aspartate/glutamate, and Mg-ATP/Pi carriers using robotic transport assays. It was found that, contrary to the literature, …

Magnetic phases of large-spin ultracold bosons: quantum dimer models and spin liquid phases
… spin this Hamiltonian produces a type of quantum dimer model (QDM), which are known to possess QSL phases. We derive the QDM parameters <em>t, t</em>′ and <em>V</em> as a function of spin on several lattices, finding they scale with the inverse number of Zeeman sublevels. We then determine the …

Macroscopic behaviour of Lipschitz random surfaces
… Random fields and random surfaces serve as toy models for analysing several phenomena in statistical physics: examples include percolation models, the Ising model, dimer models, the discrete Gaussian free field, and uniformly random Lipschitz functions. We analyse the specific free energy …

Computational investigations of cellular functions: Three cases on membrane morphogenesis, organization and assembly of a multi-protein complex, and the molecular origin of muscle elasticity
… center (RC) and, together with PufX, forms a dimeric (RC-LH1-PufX)2 protein complex known as the photosynthetic core complex. In LH2-deficient Rba . sphaeroides mutants, core complex dimers aggregate into tubular vesicles with a radius of ∼25-55 nm, making core complex dimer one of the few …

Pair density wave superconducting states and statistical mechanics of dimers
… its topological aspects in a one dimensional model and its appearance in a quasi-one dimensional system. On the other hand, chapter 5 is focused on the investigation of the classical statistical mechanics properties of dimers, in particular, the dimer model on the Aztec diamond graph and its …
