Dimer statistics on the Möbius strip and the Klein bottle

چکیده
Closed-form expressions are obtained for the generating function of close-packed dimers on a 2M × 2N simple quartic lattice embedded on a Möbius strip and a Klein bottle. Finite-size corrections are also analyzed and compared with those under cylindrical and free boundary conditions. Particularly, it is found that, for large lattices of the same size and with a square symmetry, the number of dimer configurations on a Möbius strip is 70.2% of that on a cylinder. We also establish two identities relating dimer generating functions for Möbius strips and cylinders.

Finitized Conformal Spectra of the Ising Model on the Klein Bottle and Möbius Strip
We study the conformal spectra of the critical square lattice Ising model on the Klein bottle andMöbius strip using Yang-Baxter techniques and the solution of functional equations. In particular, we obtain expressions for the finitized conformal partition functions in terms of finitized Virasoro characters. This demonstrates that Yang-Baxter techniques and functional equations can be used to st...

متن کاملFrom Möbius Bands to Klein-Knottles
A construction of various immersed Klein bottles that belong to different regular homotopy classes, and which thus cannot be smoothly transformed into one another, is introduced. It is shown how these shapes can be partitioned into two Möbius bands and how the twistedness of these bands defines the homotopy type. Some wild and artistic variants of Klein bottles are presented for their aesthetic...
متن کاملIsing model on nonorientable surfaces: exact solution for the Möbius strip and the Klein bottle.
Closed-form expressions are obtained for the partition function of the Ising model on an MxN simple-quartic lattice embedded on a Möbius strip and a Klein bottle. The solutions all lead to the same bulk free energy, but for finite M and N the expressions are different depending on whether the strip width M is odd or even. Finite-size corrections at criticality are analyzed and compared with tho...
متن کاملClose-packed dimers on nonorientable surfaces
Abstract The problem of enumerating dimers on an M×N net embedded on non-orientable surfaces is considered. We solve both the Möbius strip and Klein bottle problems for all M and N with the aid of imaginary dimer weights. The use of imaginary weights simplifies the analysis, and as a result we obtain new compact solutions in the form of double products. The compact expressions also permit us to...
