Packing dimers on lattices
Yong Kong
We use computational method to investigate the number of ways to pack dimers on \emph{odd-by-odd} lattices. In this case, there is always a single vacancy in the lattices. We show…
Exact asymptotics of monomer-dimer model on rectangular semi-infinite lattices
Yong Kong
By using the asymptotic theory of Pemantle and Wilson, exact asymptotic expansions of the free energy of the monomer-dimer model on rectangular lattices in terms…
Monomer-dimer model in two-dimensional rectangular lattices with fixed dimer density
Yong Kong
The classical monomer-dimer model in two-dimensional lattices has been shown to belong to the \emph{``#P-complete''} class, which indicates the problem is computationally ``intract…
Logarithmic corrections in the free energy of monomer-dimer model on plane lattices with free boundaries
Yong Kong
Using exact computations we study the classical hard-core monomer-dimer models on m x n plane lattice strips with free boundaries. For an arbitrary number v of monomers (or vacanci…
Fermi surface and quasiparticle dynamics of Na(x)CoO2 {x=0.7} investigated by Angle-Resolved Photoemission Spectroscopy
M. Z. Hasan, Y. -D. Chuang, A. P. Kuprin +13
We present an angle-resolved photoemission study of Na0.7CoO2, the host cobaltate of the NaxCoO2.yH2O series. Our results show a large hexagonal-like hole-type Fermi surface, an ex…
Lattice vibrations and structural instability in Cesium near the cubic to tetragonal transition
Y. Kong, O. Jepsen
Under pressure cesium undergoes a transition from a high-pressure fcc phase (Cs-II) to a collapsed fcc phase (Cs-III) near 4.2GPa. At 4.4GPa there follows a transition to the tetra…
