Chaos in a Two-Dimensional Ising Spin Glass
Muriel Ney-Nifle, A. Peter Young
TL;DR
This paper investigates temperature and bond chaos in a 2D Ising spin glass using Monte Carlo simulations, finding that chaos exponents are equal for both types and consistent with zero-temperature results.
Contribution
It demonstrates the presence of chaos in a 2D Ising spin glass for both temperature and bond variations and shows the chaos exponents are identical for these cases.
Findings
Chaos detected with respect to temperature and bonds.
Chaos exponents for both cases are equal.
Exponent value aligns with zero-temperature studies.
Abstract
We study chaos in a two dimensional Ising spin glass by finite temperature Monte Carlo simulations. We are able to detect chaos with respect to temperature changes as well as chaos with respect to changing the bonds, and find that the chaos exponents for these two cases are equal. Our value for the exponent appears to be consistent with that obtained in studies at zero temperature.
