introduction

 

 

basic notions
  • dimer configurations
  • set of dimer configurations
  • partition function
  • Kasteleyn matrix

 

 

physics motivation
  • Dimer configuration can be considered as the covering of the graph by pairs of fermions connected by an edge

 

 

Termperley equivalence
  • spanning trees on \gamma rooted at x
  • Dimers on D(\gamma)

 

 

Domino tiling and height function
  • bipartite graph

 

 

energy and weight systems
  • define a weight functionon the edges of the graph \gamma
    \(w:E(\Gamma)\to \mathbb{R}_{\geq 0}\)
  • For a dimer configuration D,
    \(w(D)=\prod_{e\in D} w(e)\)
  • energy function
    \(\epsilon:E(\Gamma)\to \mathbb{R}\)
  • For a dimer configuration D,
    \(\epsilon(D)=\sum_{e\in D} \epsilon(e)\)
  • energy and weight function
    \(w(e)=\exp (-\frac{\epsilon(e)}{T})\)
  • partition function
    \(Z_{\Gamma}=\sum_{D\subset \Gamma} \prod_{e\in D} w(e)\)

         n}], {l, 1, m}], 10]
    Z[m_, n_] := Round[Sqrt[Abs[detk[m, n]]]]
