Exponents for Hamiltonian paths on random bicubic maps and KPZ

Blog Article

We evaluate the configuration exponents of various ensembles of Hamiltonian paths drawn on random planar bicubic maps.These exponents are estimated from the extrapolations of exact enumeration results for finite sizes and compared with their theoretical predictions based on the Knizhnik, read more Polyakov and Zamolodchikov (KPZ) relations, as applied to their regular counterpart on the honeycomb lattice.We show that a naive use of these relations does not reproduce the measured exponents but that a simple modification in their application may possibly correct the observed discrepancy.

We show that a similar modification is required to reproduce via the KPZ formulas some exactly known exponents iphone 13 price ohio for the problem of unweighted fully packed loops on random planar bicubic maps.
